D14.70 - Construction Adhesives

SIGNIFICANCE AND USE
4.1 Structural design based on strength-of-materials principles requires knowledge of the mechanical properties of the structural components, including adhesives. By nature of their use, the most important property of adhesive is shear strength.  
4.2 Shear strength measured by this test method is suitable for use in adhesive development, manufacturing quality control, and in materials performance specifications, as well as structural design.
SCOPE
1.1 This test method covers the determination of comparative shear properties of gap-filling adhesives in wood-to-wood joints at specified thicknesses of bondline in the dry condition, when tested on standard specimens under specified conditions of preparation, conditioning, and loading in compression. This test method is intended as an evaluation of gap-filling adhesives such as those used to bond plywood to lumber, lumber to lumber, and other similar materials in building constructions.  
1.2 This test method also may be used to determine shear properties of gap-filling adhesives in species of wood and in thicknesses of bondline other than those specified for the comparative tests of shear properties within this test method. All procedures specified herein are applicable, excepting requirements for wood species and specific gravity, and thicknesses of bondlines.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification provides the means to measure and evaluate the performance of adhesives for structural or semistructural bonding of wood-to-wood in manufactured homes. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having woodbased surfaces at the bondline. The adhesives can be classified according to resistance to deformation: Group A or structural, and Group B or semistructural. Also, the adhesives may be designated into three types, according to their recommended use based on their resistance to water and water vapor: Type 1 for interior and exterior use, Type 2 for weather-protected interior use, and Type 3 for interior use only. Different tests shall be performed in order to determine the following properties of adhesives: shear strength, gap-filling ability, total deformation resistance, moisture and temperature limitation during fabrication, high-temperature resistance, low-temperature resistance, moisture resistance, aging, oxidation resistance, and mold resistance.
SCOPE

SIGNIFICANCE AND USE
4.1 In selecting or developing a resilient flooring or carpet adhesive, it is critical to have knowledge regarding how well the adhesive will bond to the desired substrate. Shear loading simulates a common failure mode.  
4.2 The test method determines the failure shear load for the test adhesive and specific substrate combination.
SCOPE
1.1 This test method describes a procedure to measure shear strength development for adhesives used to bond resilient flooring and carpet to selected substrates.  
1.2 This test method provides a quantitative means of measuring and recording shear strength of the adhesive when it is applied to the desired substrate.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Safe and reliable mechanical properties for adhesives are necessary to achieve the full structural benefit of adhesives in bonded structural components and assemblies.  
5.2 An adhesive’s properties exhibit a natural variation or distribution of values. The allowable design stress for an adhesive must be adjusted to allow for variability and environmental effects to ensure human safety and prevent premature failure of costly structures.  
5.3 Modification factors can be applied to the allowable design stress by the design engineer as deemed appropriate for the expected service conditions of the adhesive, or in accordance with the requirements of a building code.  
5.4 The allowable properties developed under these methods apply only to the actual adhesive formulation tested and analyzed.  
5.5 The allowable properties developed for a given adhesive shall apply only to adhesive bondlines with thicknesses in the range for which data is available.
SCOPE
1.1 These test methods cover the principles for establishing allowable mechanical properties for adhesives that can be used to design adhesive-bonded joints for structural components and assemblies of wood or wood with other materials. These test methods are modeled after Practice D245.  
1.2 The properties determined are allowable shear stress, allowable tensile stress, and allowable shear modulus.  
1.3 In determination of allowable shear- and tensile-stress levels, these test methods are limited by the horizontal shear and tension perpendicular-to-the-grain capacity of the wood adherends (hard maple, Acer saccharum, Marsh.). The adhesives so tested may actually have shear or tensile allowable stresses exceeding the wood, but the determined allowable design stress levels are limited (upper bounded) by the wood in these test methods. If a wood other than hard maple is used for testing the adhesive, then the allowable strengths are upper bounded by the properties of that particular wood.  
1.4 The strength properties are determined by standard ASTM test methods. As a result, only procedural variations from the standards and special directions for applying the results are given in these test methods.  
1.5 Time-to-failure data derived from creep-rupture testing (see Test Method D4680) provide a measure of the ultimate strength of an adhesive bond as a function of time at various levels of temperature and moisture.  
1.5.1 With proper caution, useful service life at a given shear stress level may be extrapolated from relatively short loading periods.  
1.6 The resistance of the adhesive to permanent loss of properties due to aging (permanence) is assessed by means of strength tests after constant elevated-temperature and moisture aging of test specimens.  
1.6.1 If the subject adhesives will be used to bond wood that has been treated with a preservative, fire retardant, or any other chemical to modify its properties, then the permanence of the adhesive shall be tested using wood adherends treated in the same manner.  
1.7 Factors for durability, permanence, and creep derived by shear tests and analysis, are assumed to apply to tension (normal-to-the-bond) strength as well.  
1.8 Requirements for production, inspection, and certification of adhesives evaluated under these test methods are not included.  
1.9 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Certain substances in adhesives may cause discoloration of vinyl flooring. This test method provides a means of measuring the discolorations that may occur in the vinyl as a result of contact with these adhesives. Vinyl flooring specimens, either contacting or not contacting the adhesive, are exposed to heat and UVA light to accelerate discoloration. By means of colorimeter or spectrophotometer, color differences between exposed specimens are accurately measured. Therefore, instrumental evaluation rather than personal subjective evaluation is used to determine the amount of discoloration an adhesive may produce in vinyl flooring. This test method does not attempt to simulate or duplicate the heat and sunlight conditions that may impact vinyl floor coverings while in service.
SCOPE
1.1 This test method describes procedures and instrumentation for accurately measuring the degree of staining that may occur in vinyl flooring as a result of its contact with adhesives. Measured color differences between vinyl flooring specimens contacting the adhesive and not contacting the adhesive are expressed in the CIELAB Color-Scale System.  
1.2 This test method provides for visual evaluation of staining which may occur when vinyl flooring contacts adhesives.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SCOPE
1.1 This specification establishes minimum requirements for adhesives used for the installation of tufted or woven broadloom carpet, within a climate controlled structure, when adhered directly, and permanently, to a structurally sound and recommended substrate.  
1.2 This specification will provide the means to determine adhesive bonding variation as a result of different carpet backing systems and their usage classifications based on the traffic conditions they are subjected to.  
1.3 This specification is not applicable to specialty adhesives such as those necessary for PVC and Non-PVC backed carpet tile and broadloom where the backing would be considered homogenous in nature.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification covers minimum performance standards and test requirements for gap-filling construction adhesives for field-gluing plywood to lumber framing for floor systems. The adhesive shall conform to the strength and durability properties prescribed. The different methods for specimen's preparation are presented in details. The shear strength, gap-filling effect on strength, and durability shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers minimum performance standards and test requirements for gap-filling construction adhesives for bonding wood structural panels consisting of plywood or oriented strand board (OSB) to wood based floor system framing, particularly dimension lumber or wood I-joists, at the construction site.  
1.2 This specification provides a basis for ensuring the quality of the adhesives and is not intended as an application specification.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 The following precautionary caveat pertains only to the test method portion, Section 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method can serve as a useful tool for durability assessment and service life forecasting.  
5.1.1 This test method can be used to measure the effects of heat and moisture and the effect of their interaction on adhesives and bonded joints. Knowledge of these effects is useful to an adhesive formulator or manufacturer. Moist heat aging is particularly useful for determining the effects of acidic adhesive systems on the hydrolysis of wood adherends.  
5.1.2 This test method provides a means of comparing the rate of degradation of an unknown adhesive-adherend combination to the rate of degradation of a known combination in thermal or hydrolytic aging environments. Such a comparison can be useful to adhesive manufacturers for introducing a new product to the market and for helping designers selecting adhesives.  
5.1.3 This test method does not duplicate any natural service environment, but it does provide a means of estimating the service life of joints in similar environments. Service-life estimates are useful to designers of bonded structures or structures using bonded products.  
5.2 Service-life estimates rely on the assumption that the chemical degradation mechanism is the same at the elevated aging temperatures as at the service temperature. However, this may not be true in every case. This possibility, together with the variability in specimen preparation, in the aging exposures, and in the strength measurements, require that caution be used in accepting the estimate of service life.
SCOPE
1.1 The purpose of this test method is to estimate the resistance of adhesive-bonded joints to thermal and hydrolytic degradation.  
1.2 This test method is primarily for wood-to-wood joints but may be applied to joints of wood to other materials.  
1.3 The effects of chemicals such as fire retardants, preservatives, and extractives in the wood upon joint degradation resistance can be estimated.  
1.4 This test method does not account for the effects of stress, the other principal degrading factor, nor does it account for cyclic or variable temperature or moisture levels.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method is capable of providing shear modulus and shear strength values for adhesives with accuracy suitable for use by design engineers in predicting the characteristics of building assemblies bonded with nonrigid adhesives. Adhesive formulators will also find the method useful during the development of new adhesive systems. In general, the thick adherend lap-shear test is a useful tool in research during studies of both short- and long-term load-deformation properties of adhesives. This thick adherend lap-shear test yields a uniformity of stress distribution approaching that obtained in thin tubular butt joints subjected to torsion, which is considered to be a condition of pure shear.  
5.2 The user is cautioned that pure shear strength cannot be obtained by this test method, because some tensile and compression stresses and stress concentrations are present in the joint. The estimate of shear strength by this test method will be conservative. If pure shear strength is demanded, then Test Method E229 should be used.
SCOPE
1.1 This test method describes a method of measuring the shear modulus and rupture stress in shear of adhesives in bonded joints. The method employs lap-shear specimens with wood, metal, or composite adherends, with adhesives having shear moduli ranging up to 700 MPa (100 000 psi). This test method is suitable generally for joints in which the ratio of adherend tensile modulus to adhesive shear modulus is greater than 300 to 1. It is not suitable for adhesives that have a high shear modulus in the cured state and that also require elimination of volatile constituents during cure.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 The ability to have a sufficient open assembly time is critical when bonding a carpet. An adhesive with too short an open assembly time will not allow the installer enough time to position the carpet before the adhesive is dried beyond use. A product with too long an open assembly time will not provide enough dry time for the carpet to bond to the intended substrate without movement of the carpet.  
4.2 The test method provides a means of measuring the open assembly time for an adhesive. Use of such a test method can aid both the manufacturer to develop and the user to select the appropriate adhesive for the installation of carpet.  
4.3 Test Method C679 was used as a model for this test method.
SCOPE
1.1 This test method describes a procedure to measure open assembly time for a troweled carpet adhesive.  
1.2 This test method provides an evaluation of the ability of an adhesive to effectively wet out the intended carpet backing.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Structural design based on strength of materials principles or the theory of elasticity requires knowledge of the mechanical properties of the structural components, including adhesives. By the nature of their use, the most important adhesive properties are shear modulus and shear strength. A torsion test, such as described in Test Method E229, is theoretically the most accurate method for measuring adhesive shear properties. It is, however, impractical in many situations. For example, certain materials of construction are not readily adaptable to fabricating the thin-walled cylinders used as adherends in the torsion test. The modified-rail test does not have this disadvantage.  
5.2 Two undesirable conditions occur in the modified-rail test specimens that do not occur in butt-joined cylinders; nonuniform shear-stress distribution along the joint, and the addition of some undefined combination of tension and compression stresses to the shear stress at a given location in the joint. The modified-rail shear tool minimizes but does not eliminate these undesirable effects.  
5.3 Shear modulus, strength, and other properties are measured by the modified-rail method.
SCOPE
1.1 This test method describes equipment and procedures to measure the shear modulus and shear strength of adhesive layers between rigid adherends. The equipment may also be used for determining the adhesive’s shear creep compliance, the effects of strain history such as cyclic loading upon shear properties, and a failure criteria for biaxial stress conditions such as shear plus tension and shear plus compression.2  
1.2 High-density wood shall be the preferred substrate. The practical upper limit on the shear modulus that can be measured is determined by the shear modulus of the adherends and by the strain measuring device. Thus, the practical limit of adhesive shear modulus that can be measured using high-density wood adherends is about 690 MPa (1 × 105 psi).  
Note 1: Wood-base composites, metal, plastic, reinforced plastics, and other common construction materials may also be used for adherends.  
1.3 The range of specimen dimensions that can be tested are: width 1.59 to 12.70 mm (0.0625 to 0.500 in.), length 102 to 203 mm (4 to 8 in.), and adherend thickness 13 to 25 mm (0.50 to 1.00 in.). The standard specimen dimensions shall be: width 3.18 mm (0.125 in.), length 203 mm (8 in.), and adherend thickness 19 mm (0.75 in.). Bondline thicknesses from 0.15 to 3.18 mm (0.006 to 0.125 in.) may be tested.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method is useful to the adhesive manufacturer in research and development or in manufacturing control. The results are also used for specification acceptance or as a guide in adhesive selection.  
5.2 The provisions for testing bonded specimens as well as free films are made for two purposes. First, it is possible for an interaction to occur between oxygen and chemicals or degradation products that may affect the degradation of the bonded joints strength. Second, some increase in strength due to oxidative crosslinking may not be detrimental in a bonded assembly and in fact may be beneficial. Adhesives of this behavior are not satisfactorily tested by a film flexibility test.  
5.3 Some users of this test method will be most interested in the performance of the bonded joint; some will be most interested in the performance of the adhesive. In the latter case, it is important to note that the true variance (error mean square) of the strength of the adhesive may be obscured when the tested control specimens or the tested aged specimens show wood failure.  
5.4 Conflict of Procedure—If the procedures of this test method conflict with those of detailed product specifications or manufacturer's use instructions for a particular material, then use the latter.
SCOPE
1.1 This test method describes how to estimate the relative resistance to deterioration of adhesive films and adhesive-bonded joints placed in a high-pressure oxygen environment. The instructions include both wood-to-wood and wood-to-metal joints as well as free film of adhesive. The effects of chemicals such as fire retardants, preservatives, or wood extractives, can be evaluated by using materials containing these chemicals for adherends.  
1.2 This test method is primarily intended for elastomer-based construction adhesives, but is also applicable to other types of adhesives that may be susceptible to oxygen degradation. This accelerated test does not correlate exactly with the natural aging of the adhesive because of the varied conditions of natural aging and the absence of factors such as moisture and stress. The results of this accelerated test are only comparative and must be evaluated against the performance of bonded joints whose natural and accelerated aging characteristics are known.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers the requirements for an adhesive which is intended for use in bonding pre-fabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a specific tensile adhesion or bond strength for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages. The adhesive shall be of uniform composition, shall be free from all ingredients that will affect its serviceability or have a deleterious effect on the acoustical material, shall not liberate toxic gases or fumes under normal conditions of use and application, nor shall it contain irritating substances. Tests shall be conducted to determine the following adhesive properties: surface adherence; wetting; tensile and adhesion strengths; volume shrinkage; cracking; and plasticity to permit indentation. The specimens shall also be subjected to migration or bleeding and storage tests.
SCOPE
1.1 This specification covers an adhesive for bonding prefabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a tensile adhesion (bond strength) of not less than 3.45 × 104 dynes/cm2 (1/2 lb/in.2) for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages.
Note 1: Cleanliness of Surface—The surface to which the acoustical material is applied with the adhesive should be clean, sound, and dry. Surface coatings should be removed if their nature indicates an unsatisfactory installation, so that the adhesive can be applied to the base. When the adhesive is to be applied on a painted surface, test tile should be applied for 48 h to determine suitable adherence of the coating by examination. Acoustical adhesives are not intended to be applied to surfaces that are moist and that have an alkaline reaction, or that may later become moist or alkaline. Such surfaces, as concrete or plaster, should be properly dried and aged before applying the adhesive.
Note 2: Load—This adhesive is not recommended as a sole means of holding acoustical materials weighing more than 121 kg/m2  (21/2 lb/ft2) to ceiling surfaces.
Note 3: Amount and Condition of Material—It is recommended that sufficient adhesive be used so that there is a contact surface of not less than 1.2 × 104 cm2/m2 (20 in.2/ft2) of acoustical material, with a minimum thickness of 0.3 cm (1/8 in.) and that the adhesive be applied in four separate nearly spherical portions of approximately equal size near the corners for a standard 30.5 by 30.5-cm (12 by 12-in.) tile. Fewer than or more than four portions for 30.5 by 30.5-cm tile are not recommended due to difficulty in leveling and in securing effective contact area on all portions. Adhesives that are hard, or do not wet the surface, or are difficult to spread should not be used.
Note 4: Rigidity of Base Surfaces—It is necessary that the material forming the base to which the adhesive is attached should be relatively smooth, firm, and rigid. If the pressure of applying tile and adhesive causes the base material to deflect excessively, tile previously applied may have their adhesive bond broken. This occurs on some types of gypsum board suspension systems.
Note 5: Aging—To date, no accelerated aging tests for adhesives have been developed to duplicate exactly aging in service. The aging tests in this specification are designed to accelerate the aging process and to test various manifestations of aging, and are intended to be satisfactory for comparing one adhesive with another; they do not necessarily reflect aging characteristics on an absolute basis. Purchasers of adhesives should receive from the manufacturer additional warranties and assurances of performance o...

SIGNIFICANCE AND USE
5.1 The application procedures in these test methods yield films free of the irregularities, artifacts, and variations inherent in brushing, spraying, or trowelling. Accordingly, these test methods measure the strength of autohesive bonds between two autohesive films whose topography is characteristic of the autohesive itself rather than the artifacts of the application procedure. It is recommended that this information be considered in extrapolating results from these test methods.  
5.2 The magnitude of the measured bond strengths also depends on other factors such as film thickness, the manner in which pressure is applied, the magnitude and duration of the application of pressure, and the temperature and humidity at various stages of the test. Accordingly, these parameters should be chosen in a manner consistent with the end use of the autohesive.  
5.3 In case of a dispute arising from differences in reported results when using these test methods for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to diagnose the causes for lack of repeatability between their laboratories. Competent statistical assistance is recommended for the investigation of precision. As a minimum, the two parties should select a group of test specimens and visually examine their failure modes. The average results from the two laboratories should then be compared using Student’s t-test for unpaired data and an acceptable probability level should be chosen by the two parties before testing is begun.
FIG. 1 One Type of Knife Applicator
SCOPE
1.1 These test methods cover procedures by which autohesives can be tested in four commonly practiced stressing modes, namely: compression shear, cleavage, climbing drum peel, and T-peel, and in various combinations of rigid-to-rigid, flexible-to-rigid, and flexible-to-flexible adherends that include wood, aluminum, steel flakeboard, and plastic laminates. Quantitative test methods that involve bond formation by impact are also provided. Three pressure modes are provided: static, roller, and impact. Because there are many types of contact adhesives being used to bond many different materials under widely differing conditions, these test methods are designed to allow the user to select the test mode, coating thickness, temperature and relative humidity conditions, pressure magnitude and mode, open time, and bond-conditioning time.  
1.1.1 The bond-formation process used with autohesives is unlike that of all other adhesives and in consequence, testing of autohesives requires methods that are unlike those provided by other ASTM standards. See Annex A1.  
1.2 A choice of adherends is available in each test mode. The combination of adherends that can be bonded together is limited to those shown in Appendix X1.  
1.3 Methods for application of pressure are available in each test mode. For a particular combination of substrates, the means available for application of pressure are limited to those shown in Appendix X2.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 7.5.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification addresses the physical, chemical and test requirements for structural insulated panel (SIP) adhesives suitable for the bonding of oriented strand boards (OSB) to rigid cellular polystyrene thermal insulation core materials for general structural use. Douglas-fir to Douglas-fir assemblies shall pass the following qualification requirements when tested in accordance with referenced ASTM documents enumerated herein: block shear strength (dry shear, soak/re-dry, oxidation resistance, and mold resistance); tensile strength (dry tensile bond strength, soak/re-dry, and mold resistance); and creep resistance.

ABSTRACT
This specification provides the means to measure and evaluate the performance of adhesives for structural or semistructural bonding of wood-to-wood in manufactured homes. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having woodbased surfaces at the bondline. The adhesives can be classified according to resistance to deformation: Group A or structural, and Group B or semistructural. Also, the adhesives may be designated into three types, according to their recommended use based on their resistance to water and water vapor: Type 1 for interior and exterior use, Type 2 for weather-protected interior use, and Type 3 for interior use only. Different tests shall be performed in order to determine the following properties of adhesives: shear strength, gap-filling ability, total deformation resistance, moisture and temperature limitation during fabrication, high-temperature resistance, low-temperature resistance, moisture resistance, aging, oxidation resistance, and mold resistance.

ABSTRACT
This specification establishes minimum requirements for adhesives used for the installation of tufted or woven broadloom carpet, within a climate controlled structure, when adhered directly, and permanently, to a structurally sound and recommended substrate. It provides the means to determine adhesive bonding variation as a result of different carpet backing systems and their usage classifications based on the traffic conditions they are subjected to. This specification also describes classification, standard conditioning, chemical composition, physical properties, performance requirements, sampling, certification, and packaging and package marking.
SCOPE
1.1 This specification establishes minimum requirements for adhesives used for the installation of tufted or woven broadloom carpet, within a climate controlled structure, when adhered directly, and permanently, to a structurally sound and recommended substrate.  
1.2 This specification will provide the means to determine adhesive bonding variation as a result of different carpet backing systems and their usage classifications based on the traffic conditions they are subjected to.  
1.3 This specification is not applicable to specialty adhesives such as those necessary for PVC and Non-PVC backed carpet tile and broadloom where the backing would be considered homogenous in nature.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
Safe and reliable mechanical properties for adhesives are necessary to achieve the full structural benefit of adhesives in bonded structural components and assemblies.
An adhesive's properties exhibit a natural variation or distribution of values. The allowable design stress for an adhesive must be adjusted to allow for variability and environmental effects to ensure human safety and prevent premature failure of costly structures.
Modification factors can be applied to the allowable design stress by the design engineer as deemed appropriate for the expected service conditions of the adhesive, or in accordance with the requirements of a building code.
The allowable properties developed under these methods apply only to the actual adhesive formulation tested and analyzed.  
The allowable properties developed for a given adhesive shall apply only to adhesive bondlines with thicknesses in the range for which data is available.
SCOPE
1.1 These test methods cover the principles for establishing allowable mechanical properties for adhesives that can be used to design adhesive-bonded joints for structural components and assemblies of wood or wood with other materials. These test methods are modeled after Practice D245.
1.2 The properties determined are allowable shear stress, allowable tensile stress, and allowable shear modulus.
1.3 In determination of allowable shear- and tensile-stress levels, these test methods are limited by the horizontal shear and tension perpendicular-to-the-grain capacity of the wood adherends (hard maple, Acer saccharum, Marsh.). The adhesives so tested may actually have shear or tensile allowable stresses exceeding the wood, but the determined allowable design stress levels are limited (upper bounded) by the wood in these test methods. If a wood other than hard maple is used for testing the adhesive, then the allowable strengths are upper bounded by the properties of that particular wood.
1.4 The strength properties are determined by standard ASTM test methods. As a result, only procedural variations from the standards and special directions for applying the results are given in these test methods.  
1.5 Time-to-failure data derived from creep-rupture testing (see Test Method D4680) provide a measure of the ultimate strength of an adhesive bond as a function of time at various levels of temperature and moisture.
1.5.1 With proper caution, useful service life at a given shear stress level may be extrapolated from relatively short loading periods.  
1.6 The resistance of the adhesive to permanent loss of properties due to aging (permanence) is assessed by means of strength tests after constant elevated-temperature and moisture aging of test specimens.  
1.6.1 If the subject adhesives will be used to bond wood that has been treated with a preservative, fire retardant, or any other chemical to modify its properties, then the permanence of the adhesive shall be tested using wood adherends treated in the same manner.
1.7 Factors for durability, permanence, and creep derived by shear tests and analysis, are assumed to apply to tension (normal-to-the-bond) strength as well.
1.8 Requirements for production, inspection, and certification of adhesives evaluated under these test methods are not included.
1.9 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

SIGNIFICANCE AND USE
Certain substances in adhesives may cause discoloration of vinyl flooring. This test method provides a means of measuring the discolorations that may occur in the vinyl as a result of contact with these adhesives. Vinyl flooring specimens, either contacting or not contacting the adhesive, are exposed to heat and UVA light to accelerate discoloration. By means of colorimeter or spectrophotometer, color differences between exposed specimens are accurately measured. Therefore, instrumental evaluation rather than personal subjective evaluation is used to determine the amount of discoloration an adhesive may produce in vinyl flooring. This test method does not attempt to simulate or duplicate the heat and sunlight conditions that may impact vinyl floor coverings while in service.
SCOPE
1.1 This test method describes procedures and instrumentation for accurately measuring the degree of staining that may occur in vinyl flooring as a result of its contact with adhesives. Measured color differences between vinyl flooring specimens contacting the adhesive and not contacting the adhesive are expressed in the CIELAB Color-Scale System.
1.2 This test method provides for visual evaluation of staining which may occur when vinyl flooring contacts adhesives.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method can serve as a useful tool for durability assessment and service life forecasting.
This test method can be used to measure the effects of heat and moisture and the effect of their interaction on adhesives and bonded joints. Knowledge of these effects is useful to an adhesive formulator or manufacturer. Moist heat aging is particularly useful for determining the effects of acidic adhesive systems on the hydrolysis of wood adherends.
This test method provides a means of comparing the rate of degradation of an unknown adhesive-adherend combination to the rate of degradation of a known combination in thermal or hydrolytic aging environments. Such a comparison can be useful to adhesive manufacturers for introducing a new product to the market and for helping designers selecting adhesives.
This test method does not duplicate any natural service environment, but it does provide a means of estimating the service life of joints in similar environments. Service-life estimates are useful to designers of bonded structures or structures using bonded products.
Service-life estimates rely on the assumption that the chemical degradation mechanism is the same at the elevated aging temperatures as at the service temperature. However, this may not be true in every case. This possibility, together with the variability in specimen preparation, in the aging exposures, and in the strength measurements, require that caution be used in accepting the estimate of service life.
SCOPE
1.1 The purpose of this test method is to estimate the resistance of adhesive-bonded joints to thermal and hydrolytic degradation.
1.2 This test method is primarily for wood-to-wood joints but may be applied to joints of wood to other materials.
1.3 The effects of chemicals such as fire retardants, preservatives, and extractives in the wood upon joint degradation resistance can be estimated.
1.4 This test method does not account for the effects of stress, the other principal degrading factor, nor does it account for cyclic or variable temperature or moisture levels.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
In selecting or developing a carpet adhesive, it is critical to have knowledge regarding how well the adhesive will bond to the desired underlayment. Shear loading simulates a common failure mode.
The test method determines the failure shear load for the test adhesive and specific underlayment combination.
SCOPE
1.1 This test method describes a procedure to measure shear strength development for adhesives used to bond carpet adhesives to selected underlayments.
1.2 This test method provides a quantitative means of measuring and recording shear strength of the adhesive when it is applied to the desired underlayment.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is useful to the adhesive manufacturer in research and development or in manufacturing control. The results are also used for specification acceptance or as a guide in adhesive selection.
The provisions for testing bonded specimens as well as free films are made for two purposes. First, it is possible for an interaction to occur between oxygen and chemicals or degradation products that may affect the degradation of the bonded joints strength. Second, some increase in strength due to oxidative crosslinking may not be detrimental in a bonded assembly and in fact may be beneficial. Adhesives of this behavior are not satisfactorily tested by a film flexibility test.
Some users of this test method will be most interested in the performance of the bonded joint; some will be most interested in the performance of the adhesive. In the latter case, it is important to note that the true variance (error mean square) of the strength of the adhesive may be obscured when the tested control specimens or the tested aged specimens show wood failure.
Conflict of Procedure—If the procedures of this test method conflict with those of detailed product specifications or manufacturer's use instructions for a particular material, then use the latter.
SCOPE
1.1 This test method describes how to estimate the relative resistance to deterioration of adhesive films and adhesive-bonded joints placed in a high-pressure oxygen environment. The instructions include both wood-to-wood and wood-to-metal joints as well as free film of adhesive. The effects of chemicals such as fire retardants, preservatives, or wood extractives, can be evaluated by using materials containing these chemicals for adherends.
1.2 This test method is primarily intended for elastomer-based construction adhesives, but is also applicable to other types of adhesives that may be susceptible to oxygen degradation. This accelerated test does not correlate exactly with the natural aging of the adhesive because of the varied conditions of natural aging and the absence of factors such as moisture and stress. The results of this accelerated test are only comparative and must be evaluated against the performance of bonded joints whose natural and accelerated aging characteristics are known.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
The application procedures in these test methods yield films free of the irregularities, artifacts, and variations inherent in brushing, spraying, or trowelling. Accordingly, these test methods measure the strength of autohesive bonds between two autohesive films whose topography is characteristic of the autohesive itself rather than the artifacts of the application procedure. It is recommended that this information be considered in extrapolating results from these test methods.
The magnitude of the measured bond strengths also depends on other factors such as film thickness, the manner in which pressure is applied, the magnitude and duration of the application of pressure, and the temperature and humidity at various stages of the test. Accordingly, these parameters should be chosen in a manner consistent with the end use of the autohesive.
In case of a dispute arising from differences in reported results when using these test methods for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to diagnose the causes for lack of repeatability between their laboratories. Competent statistical assistance is recommended for the investigation of precision. As a minimum, the two parties should select a group of test specimens and visually examine their failure modes. The average results from the two laboratories should then be compared using Student's t-test for unpaired data and an acceptable probability level should be chosen by the two parties before testing is begun.
SCOPE
1.1 These test methods cover procedures by which autohesives can be tested in four commonly practiced stressing modes, namely: compression shear, cleavage, climbing drum peel, and T-peel, and in various combinations of rigid-to-rigid, flexible-to-rigid, and flexible-to-flexible adherends that include wood, aluminum, steel flakeboard, and plastic laminates. Quantitative test methods that involve bond formation by impact are also provided. Three pressure modes are provided: static, roller, and impact. Because there are many types of contact adhesives being used to bond many different materials under widely differing conditions, these test methods are designed to allow the user to select the test mode, coating thickness, temperature and relative humidity conditions, pressure magnitude and mode, open time, and bond-conditioning time.
1.1.1 The bond-formation process used with autohesives is unlike that of all other adhesives and in consequence, testing of autohesives requires methods that are unlike those provided by other ASTM standards. See Annex A1.
1.2 A choice of adherends is available in each test mode. The combination of adherends that can be bonded together is limited to those shown in Appendix X1.
1.3 Methods for application of pressure are available in each test mode. For a particular combination of substrates, the means available for application of pressure are limited to those shown in Appendix X2.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 7.5.

ABSTRACT
This specification covers minimum performance standards and test requirements for gap-filling construction adhesives for field-gluing plywood to lumber framing for floor systems. The adhesive shall conform to the strength and durability properties prescribed. The different methods for specimen's preparation are presented in details. The shear strength, gap-filling effect on strength, and durability shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers minimum performance standards and test requirements for gap-filling construction adhesives for bonding plywood to lumber framing, particularly floor joists, at the construction site.
1.2 This specification provides a basis for ensuring the quality of the adhesives and is not intended as an application specification.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The following precautionary caveat pertains only to the test method portion, Section 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is capable of providing shear modulus and shear strength values for adhesives with accuracy suitable for use by design engineers in predicting the characteristics of building assemblies bonded with nonrigid adhesives. Adhesive formulators will also find the method useful during the development of new adhesive systems. In general, the thick adherend lap-shear test is a useful tool in research during studies of both short- and long-term load-deformation properties of adhesives. This thick adherend lap-shear test yields a uniformity of stress distribution approaching that obtained in thin tubular butt joints subjected to torsion, which is considered to be a condition of pure shear.
The user is cautioned that pure shear strength cannot be obtained by this test method, because some tensile and compression stresses and stress concentrations are present in the joint. The estimate of shear strength by this test method will be conservative. If pure shear strength is demanded, then Test Method E229 should be used.
SCOPE
1.1 This test method describes a method of measuring the shear modulus and rupture stress in shear of adhesives in bonded joints. The method employs lap-shear specimens with wood, metal, or composite adherends, with adhesives having shear moduli ranging up to 700 MPa (100 000 psi). This test method is suitable generally for joints in which the ratio of adherend tensile modulus to adhesive shear modulus is greater than 300 to 1. It is not suitable for adhesives that have a high shear modulus in the cured state and that also require elimination of volatile constituents during cure.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
The ability to have a sufficient open assembly time is critical when bonding a carpet. An adhesive with too short an open assembly time will not allow the installer enough time to position the carpet before the adhesive is dried beyond use. A product with too long an open assembly time will not provide enough dry time for the carpet to bond to the intended substrate without movement of the carpet.
The test method provides a means of measuring the open assembly time for an adhesive. Use of such a test method can aid both the manufacturer to develop and the user to select the appropriate adhesive for the installation of carpet.
Test Method C679 was used as a model for this test method.
SCOPE
1.1 This test method describes a procedure to measure open assembly time for a troweled carpet adhesive.
1.2 This test method provides an evaluation of the ability of an adhesive to effectively wet out the intended carpet backing.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification covers the requirements for an adhesive which is intended for use in bonding pre-fabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a specific tensile adhesion or bond strength for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages. The adhesive shall be of uniform composition, shall be free from all ingredients that will affect its serviceability or have a deleterious effect on the acoustical material, shall not liberate toxic gases or fumes under normal conditions of use and application, nor shall it contain irritating substances. Tests shall be conducted to determine the following adhesive properties: surface adherence; wetting; tensile and adhesion strengths; volume shrinkage; cracking; and plasticity to permit indentation. The specimens shall also be subjected to migration or bleeding and storage tests.
SCOPE
1.1 This specification covers an adhesive for bonding prefabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a tensile adhesion (bond strength) of not less than 3.45 × 104  dynes/cm2  (½ lb/in.2) for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages.
Note 1—Cleanliness of SurfaceThe surface to which the acoustical material is applied with the adhesive should be clean, sound, and dry. Surface coatings should be removed if their nature indicates an unsatisfactory installation, so that the adhesive can be applied to the base. When the adhesive is to be applied on a painted surface, test tile should be applied for 48 h to determine suitable adherence of the coating by examination. Acoustical adhesives are not intended to be applied to surfaces that are moist and that have an alkaline reaction, or that may later become moist or alkaline. Such surfaces, as concrete or plaster, should be properly dried and aged before applying the adhesive.

ABSTRACT
This specification establishes minimum performance requirements for determining strength, aging, and working properties of expandable foam adhesives intended for bonding back surfaces of gypsum wallboards of all thicknesses to wood framing. Minimum physical and performance requirements are specified for all measured properties of adhesives and adhesive bonds. Shear strength, tensile strength, adhesive open assembly time determination, substrate wet-out by adhesive, accelerated adhesive aging, freeze-thaw stability, suitability of a laminating adhesive for vinyl-covered wallboard, suitability for stain resistance for vinyl-covered wallboard, and gap filling tests shall be performed to conform to the specified requirements.
SCOPE
1.1 This specification establishes minimum performance requirements for determining strength, aging, and working properties of expandable foam adhesives intended for bonding back surfaces of gypsum wallboards of all thicknesses to wood framing. Minimum physical and performance requirements are specified for all measured properties of adhesives and adhesive bonds.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
During application, end users typically remove the adhesive from the container using the trowel and spread it onto the desired substrate. Adhesives with good rheological characteristics, therefore, will allow trowel retention. Adhesives with poor rheological characteristics tend to be unacceptable because they cannot be picked up by a trowel.
Bead configuration is important in order to provide proper wetting/contact of the carpet backing. Beads drawn with a trowel, which show a nonslumping ridge, are preferred because they allow good contact to both substrates.
Measurement of the slump resistance of the adhesive will allow an end user to know if an adhesive is capable of both adhering well to the trowel during application and maintain a nonflowing adhesive ridge.
SCOPE
1.1 This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus.
1.2 This test method provides a visual evaluation to relate troweled bead profile and trowel pickup.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

ABSTRACT
This specification addresses the physical, chemical and test requirements for structural insulated panel (SIP) adhesives suitable for the bonding of oriented strand boards (OSB) to rigid cellular polystyrene thermal insulation core materials for general structural use. Douglas-fir to Douglas-fir assemblies shall pass the following qualification requirements when tested in accordance with referenced ASTM documents enumerated herein: block shear strength (dry shear, soak/re-dry, oxidation resistance, and mold resistance); tensile strength (dry tensile bond strength, soak/re-dry, and mold resistance); and creep resistance. OSB to core to OSB assemblies shall, alternatively, be tested and pass shear strength and tensile (flat wise) bond strength requirements as well.
SIGNIFICANCE AND USE
This specification addresses minimum performance criteria for adhesives used to laminate oriented strand board (OSB) structural panel facing material to expanded or extruded polystyrene core materials. Adhesive performance is based on tests that simulate exposure to moisture, temperature, seasonal weathering, and creep. Additionally, the adhesive is to demonstrate resistance to oxidation, mold, chemical reagents, and compatibility to the specific laminating materials.
The adhesive manufacturers can use this specification for new product development and quality control purposes.
Structural insulated panel manufacturers rely on an adhesive performance specification that determines its suitability before use.
Performance of the SIP adhesive when evaluated in accordance with this specification aids in determining the suitability of the adhesive for laminating OSB facings to rigid cellular polystyrene core materials in the manufacture of structural insulated panels.
SCOPE
1.1 This specification is designed to evaluate adhesives suitable for the bonding of oriented strand board (OSB) to rigid cellular polystyrene insulation core materials for general structure use.
1.2 The requirements of the structural insulated panel (SIP) adhesive are based on the performance of the adhesive as measured by:
1.2.1 Resistance to shear by compression loading in ambient conditions and after accelerated aging.
1.2.2 Resistance to tensile loading in ambient conditions and after accelerated aging.
1.2.3 Resistance to creep (deformation) under static load in ambient conditions and after accelerated aging.
1.2.4 Tensile and shear strength to polystyrene core materials.
1.3 The classification of the adhesive formulation is based on, but not limited to the adhesive’s industry accepted generic names, for example: phenol-resorcinol, emulsion polymer isocyanate, one and two-part urethane. The type of adhesive application and curing terminology are also usually included for classification purposes such as cold-setting phenol resorcinol, heat-cured phenol resorcinol, and hot melt one component urethane.
1.4 Evaluation of adhesive performance at high temperature conditions, such as during a fire exposure, is beyond the scope of this specification.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

SIGNIFICANCE AND USE
Structural design based on strength-of-materials principles requires knowledge of the mechanical properties of the structural components, including adhesives. By nature of their use, the most important property of adhesive is shear strength.
Shear strength measured by this test method is suitable for use in adhesive development, manufacturing quality control, and in materials performance specifications, as well as structural design.
SCOPE
1.1 This test method covers the determination of comparative shear properties of gap-filling adhesives in wood-to-wood joints at specified thicknesses of bondline in the dry condition, when tested on standard specimens under specified conditions of preparation, conditioning, and loading in compression. This test method is intended as an evaluation of gap-filling adhesives such as those used to bond plywood to lumber, lumber to lumber, and other similar materials in building constructions.
1.2 This test method also may be used to determine shear properties of gap-filling adhesives in species of wood and in thicknesses of bondline other than those specified for the comparative tests of shear properties within this test method. All procedures specified herein are applicable, excepting requirements for wood species and specific gravity, and thicknesses of bondlines.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

SIGNIFICANCE AND USE
Safe and reliable mechanical properties for adhesives are necessary to achieve the full structural benefit of adhesives in bonded structural components and assemblies.
An adhesive’properties exhibit a natural variation or distribution of values. The allowable design stress for an adhesive must be adjusted to allow for variability and environmental effects to ensure human safety and prevent premature failure of costly structures.
Modification factors can be applied to the allowable design stress by the design engineer as deemed appropriate for the expected service conditions of the adhesive, or in accordance with the requirements of a building code.
The allowable properties developed under these methods apply only to the actual adhesive formulation tested and analyzed.  
The allowable properties developed for a given adhesive shall apply only to adhesive bondlines with thicknesses in the range for which data is available.
SCOPE
1.1 These test methods cover the principles for establishing allowable mechanical properties for adhesives that can be used to design adhesive-bonded joints for structural components and assemblies of wood or wood with other materials. These test methods are modeled after Test Method D 245.
1.2 The properties determined are allowable shear stress, allowable tensile stress, and allowable shear modulus.
1.3 In determination of allowable shear- and tensile-stress levels, these test methods are limited by the horizontal shear and tension perpendicular-to-the-grain capacity of the wood adherends (hard maple, Acer saccharum, Marsh.). The adhesives so tested may actually have shear or tensile allowable stresses exceeding the wood, but the determined allowable design stress levels are limited (upper bounded) by the wood in these test methods. If a wood other than hard maple is used for testing the adhesive, then the allowable strengths are upper bounded by the properties of that particular wood.
1.4 The strength properties are determined by standard ASTM test methods. As a result, only procedural variations from the standards and special directions for applying the results are given in these test methods.
1.5 Time-to-failure data derived from creep-rupture testing (see Test Method D 4680) provide a measure of the ultimate strength of an adhesive bond as a function of time at various levels of temperature and moisture.
1.5.1 With proper caution, useful service life at a given shear stress level may be extrapolated from relatively short loading periods.
1.6 The resistance of the adhesive to permanent loss of properties due to aging (permanence) is assessed by means of strength tests after constant elevated-temperature and moisture aging of test specimens.
1.6.1 If the subject adhesives will be used to bond wood that has been treated with a preservative, fire retardant, or any other chemical to modify its properties, then the permanence of the adhesive shall be tested using wood adherends treated in the same manner.
1.7 Factors for durability, permanence, and creep derived by shear tests and analysis, are assumed to apply to tension (normal-to-the-bond) strength as well.
1.8 Requirements for production, inspection, and certification of adhesives evaluated under these test methods are not included.
1.9 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for infomration only and are not considered standard.

SCOPE

ABSTRACT
This specification provides the means to measure and evaluate the performance of adhesives for structural or semistructural bonding of wood-to-wood in manufactured homes. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having woodbased surfaces at the bondline. The adhesives can be classified according to resistance to deformation: Group A or structural, and Group B or semistructural. Also, the adhesives may be designated into three types, according to their recommended use based on their resistance to water and water vapor: Type 1 for interior and exterior use, Type 2 for weather-protected interior use, and Type 3 for interior use only. Different tests shall be performed in order to determine the following properties of adhesives: shear strength, gap-filling ability, total deformation resistance, moisture and temperature limitation during fabrication, high-temperature resistance, low-temperature resistance, moisture resistance, aging, oxidation resistance, and mold resistance.
SCOPE
1.1 This specification provides the means to measure and evaluate the performance of adhesives for structural or semi-structural bonding of wood-to-wood in manufactured homes.

SIGNIFICANCE AND USE
Certain substances in adhesives may cause discoloration of vinyl flooring. This test method provides a means of measuring the discolorations that may occur in the vinyl as a result of contact with these adhesives. Vinyl flooring specimens, either contacting or not contacting the adhesive, are exposed to heat and UVA light to accelerate discoloration. By means of colorimeter or spectrophotometer, color differences between exposed specimens are accurately measured. Therefore, instrumental evaluation rather than personal subjective evaluation is used to determine the amount of discoloration an adhesive may produce in vinyl flooring. This test method does not attempt to simulate or duplicate the heat and sunlight conditions that may impact vinyl floor coverings while in service.
SCOPE
1.1 This test method describes procedures and instrumentation for accurately measuring the degree of staining that may occur in vinyl flooring as a result of its contact with adhesives. Measured color differences between vinyl flooring specimens contacting the adhesive and not contacting the adhesive are expressed in the CIELAB Color-Scale System.
1.2 This test method provides for visual evaluation of staining which may occur when vinyl flooring contacts adhesives.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method can serve as a useful tool for durability assessment and service life forecasting.
5.1.1 This test method can be used to measure the effects of heat and moisture and the effect of their interaction on adhesives and bonded joints. Knowledge of these effects is useful to an adhesive formulator or manufacturer. Moist heat aging is particularly useful for determining the effects of acidic adhesive systems on the hydrolysis of wood adherends.
5.1.2 This test method provides a means of comparing the rate of degradation of an unknown adhesive-adherend combination to the rate of degradation of a known combination in thermal or hydrolytic aging environments. Such a comparison can be useful to adhesive manufacturers for introducing a new product to the market and for helping designers selecting adhesives.
5.1.3 This test method does not duplicate any natural service environment, but it does provide a means of estimating the service life of joints in similar environments. Service-life estimates are useful to designers of bonded structures or structures using bonded products.
Service-life estimates rely on the assumption that the chemical degradation mechanism is the same at the elevated aging temperatures as at the service temperature. However, this may not be true in every case. This possibility, together with the variability in specimen preparation, in the aging exposures, and in the strength measurements, require that caution be used in accepting the estimate of service life.
SCOPE
1.1 The purpose of this test method is to estimate the resistance of adhesive-bonded joints to thermal and hydrolytic degradation.
1.2 This test method is primarily for wood-to-wood joints but may be applied to joints of wood to other materials.
1.3 The effects of chemicals such as fire retardants, preservatives, and extractives in the wood upon joint degradation resistance can be estimated.
1.4 This test method does not account for the effects of stress, the other principal degrading factor, nor does it account for cyclic or variable temperature or moisture levels.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
The application procedures in these test methods yield films free of the irregularities, artifacts, and variations inherent in brushing, spraying, or trowelling. Accordingly, these test methods measure the strength of autohesive bonds between two autohesive films whose topography is characteristic of the autohesive itself rather than the artifacts of the application procedure. It is recommended that this information be considered in extrapolating results from these test methods.
The magnitude of the measured bond strengths also depends on other factors such as film thickness, the manner in which pressure is applied, the magnitude and duration of the application of pressure, and the temperature and humidity at various stages of the test. Accordingly, these parameters should be chosen in a manner consistent with the end use of the autohesive.
In case of a dispute arising from differences in reported results when using these test methods for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to diagnose the causes for lack of repeatability between their laboratories. Competent statistical assistance is recommended for the investigation of precision. As a minimum, the two parties should select a group of test specimens and visually examine their failure modes. The average results from the two laboratories should then be compared using Student’t-test for unpaired data and an acceptable probability level should be chosen by the two parties before testing is begun.
FIG. 1 One Type of Knife Applicator
SCOPE
1.1 These test methods cover procedures by which autohesives can be tested in four commonly practiced stressing modes, namely: compression shear, cleavage, climbing drum peel, and T-peel, and in various combinations of rigid-to-rigid, flexible-to-rigid, and flexible-to-flexible adherends that include wood, aluminum, steel flakeboard, and plastic laminates. Quantitative test methods that involve bond formation by impact are also provided. Three pressure modes are provided: static, roller, and impact. Because there are many types of contact adhesives being used to bond many different materials under widely differing conditions, these test methods are designed to allow the user to select the test mode, coating thickness, temperature and relative humidity conditions, pressure magnitude and mode, open time, and bond-conditioning time.
1.1.1 The bond-formation process used with autohesives is unlike that of all other adhesives and in consequence, testing of autohesives requires methods that are unlike those provided by other ASTM standards. See Annex A1.
1.2 A choice of adherends is available in each test mode. The combination of adherends that can be bonded together is limited to those shown in Appendix X1.
1.3 Methods for application of pressure are available in each test mode. For a particular combination of substrates, the means available for application of pressure are limited to those shown in Appendix X2.
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 7.5.

SIGNIFICANCE AND USE
In selecting or developing a carpet adhesive, it is critical to have knowledge regarding how well the adhesive will bond to the desired underlayment. Shear loading simulates a common failure mode.
