Standard Test Method for Determining the Adhesive and Cohesive Strength Between Materials in Roofing or Waterproofing Membranes and Systems

Standard Test Method for Determining the Adhesive and Cohesive Strength Between Materials in Roofing or Waterproofing Membranes and Systems

SIGNIFICANCE AND USE
5.1 This test method is useful to define the force needed to cause separation of the roofing or waterproofing system or components perpendicular to the plane of the system, and to define the weakest plane in the system.
SCOPE
1.1 This test method measures the force needed to cause separation of the components of a roofing or a waterproofing membrane system normal (perpendicular) to the plane of the membrane. The separation may be adhesive at the weakest bond, or cohesive within the weakest material. If the failure is cohesive, the adhesive strength is greater than the cohesive strength.  
1.2 The values stated in SI units are regarded as standard. The values given in parentheses are for information only.  
1.3 The 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.

Standard Specification for Adhesives for Wood-Based Materials for Construction of Manufactured Homes

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. Wood as used in this specification includes lumber, plywood, particleboard, gypsum board, and all materials having wood-based surfaces at the bondline. This specification does not cover other adhesives used in manufactured homes such as adhesives for carpet, floor tile, ceramic fixtures, plastic laminates, trim and millwork, and similar nonstructural applications.

ASTM D4680-98(2023)(Test Method)
Standard Test Method for Creep and Time to Failure of Adhesives in Static Shear by Compression Loading (Wood-to-Wood)

SIGNIFICANCE AND USE
4.1 Creep data that are obtained over a relatively short period of time in this test method can provide a measure of an adhesive bond's ability to withstand static loading in shear over a relatively long period of time. Creep measurements are made over a range of expected service conditions, including level of stress, temperature, relative humidity, and duration of load. Creep rate, creep strain, and creep modulus are calculated at the various service conditions.  
4.2 Creep data can be used to (1) predict performance of an adhesive under long-term loading, (2) characterize an adhesive, (3) compare adhesives with each other and against specifications, and (4) design structural members fabricated with an adhesive.  
4.3 Time-to-failure data provide a measure of the ultimate load-carrying ability of an adhesive bond as a function of time at various levels of stress, temperature, and relative humidity.  
4.4 With proper caution, time-to-failure data derived from relatively short loading periods can be extrapolated to estimate the useful service life of an adhesive at working levels of static stress. This property may also be used with creep data to accomplish purposes listed in 4.2.  
4.5 This test method is a research tool intended for development or evaluation of new adhesives and new product designs. The researcher may select from suggested tests those that are appropriate. However, creep and time-to-failure tests are nonroutine and can be time-consuming and expensive, so tests must be selected with care.  
4.6 The apparatus and procedures may be suitable for measuring creep properties of adhesives on substrates other than wood, such as metal, plastic, and glass, but such considerations are not within the scope of this test method.
SCOPE
1.1 This test method covers the determination of time-dependent properties of structural adhesives in wood-to-wood bonds when specimens are subjected to shearing stresses at various levels of static load, constant temperature, and relative humidity. Apparatus and procedures are provided for direct measurement of time-dependent shear deformation (creep) and time to failure of adhesive bonds under static load. Guidelines for selecting test conditions, methods for calculating creep rate, creep strain, creep modulus, and extrapolation of time to failure, are given along with methods of presenting these data.  
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, 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.

Standard Test Methods for Ability of Adhesive Films to Support or Resist the Growth of Fungi

SIGNIFICANCE AND USE
4.1 These test methods are designed to be used to determine the susceptibility of the adhesive film to biodegradation and whether the adhesive will carry into the bond line sufficient anti-fungal properties to prevent growth of fungi frequently present on the gluing equipment, on adherends, or in the adhesive as applied.  
4.2 Potato dextrose agar (PDA) provides a complete medium for the growth of fungi, while mineral salts agar (MSA) lacks a carbohydrate source and provides a less favorable medium. Use of PDA tests the adhesive film for its ability to resist the growth of fungi on its surface as well as its ability to repel a copious growth of fungi on the adjacent agar surface. Use of MSA tests the adhesive film primarily for its ability to resist the growth of fungi on its surface. When it is used, there is a reduced possibility that the growth from the agar will be mis-read as coming from the adhesive film, since fungal growth on the adjacent agar will be scant.
Note 2: The method given here using the MSA is based on Practice G21, adapted to be used with adhesives. Requirements for the use of the MSA are described in 10.2, and a mixed species of fungi is prescribed in 8.2 for the inoculum.  
4.3 The results obtained when using the procedures given in this method apply only to the species used for the testing. The test species listed in Section 8 are frequently used by laboratories to test for antifungal properties, but they are not the only ones which could be used. Selection of the fungal species to test against requires informed judgment by the testing laboratory or by the party requesting the tests. These methods are especially useful when species that have been isolated from contaminated adhesives are used as the test species (see Section 8) to aid in the selection of more effective fungicides.  
4.4 The efficacy of some biocides may change in storage due to the chemical and thermal environment to which they are subjected as components of certain adhesi...
SCOPE
1.1 These test methods test the ability of adhesive films to inhibit or support the growth of selected fungal species growing on agar plates by providing means of testing the films on two agar substrates, one which promotes microbial growth, and one which does not.  
1.2 These test methods are not appropriate for all adhesives. The activity of certain biocides may not be demonstrated by these test methods as a result of irreversible reaction with some of the medium constituents.  
Note 1: As an example, quaternary ammonium compounds are inactivated by agar.  
1.3 A test method is included for use with low-viscosity adhesives along with an alternative method for use with mastic-type adhesives.  
1.4 The values stated in SI units are to be regarded as the standard. The values 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. These test methods are designed to be used by persons trained in correct microbiological techniques. Specific precautionary statements are given in Section 7 and in 14.3.2.  
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.

ASTM D7966/D7966M-16(2023)(Test Method)
Standard Test Method for Resistance to Creep of Adhesives in Static Shear by Compression Loading (Wood-to-Wood)

SIGNIFICANCE AND USE
5.1 This test method evaluates the performance of the adhesive in laminated wood as measured by resistance to creep under static load.  
5.2 Test results from the evaluation of adhesive creep resistance, under designated environmental conditions of the test, provide a measure of the adhesive’s ability to withstand constant loading over a relatively long period of time.  
5.3 Creep measured with this test method is normally used in conjunction with specifications such as, but not limited to Specification D2559 and CSA O112.9 to confirm suitability of an adhesive to resist creep under designed loads when subjected to specific levels of stress, load duration and environmental conditions.
SCOPE
1.1 This test method covers the determination of creep properties of structural adhesives in wood-to-wood bonds when a standardized specimen is subjected to shearing stresses at various levels of static load, constant temperature, and relative humidity. Apparatus and procedures are provided for shear deformation (creep) of adhesive bonds under static load. This test method is used under the indicated conditions to evaluate resistance to creep properties of a structural wood adhesive.  
1.2 The test method is used to evaluate creep performance of adhesives suitable for the bonding of wood, including treated wood, into structural wood products for general construction, marine use, or for other uses where a high-strength general construction, creep-resistant, durable adhesive bond is required. Individual block shear specimens are prepared from adhesively bonded laminations, subjected to a constant load under various combinations of temperature and relative humidity, and the amount of creep measured.  
1.3 Creep of structural wood adhesives as measured by this test method may not be comparative to other ASTM methods and is limited to the conditions of the test and procedures contained herein.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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.

Standard Test Method for Tensile Strength of Adhesives by Means of Bar and Rod Specimens

SIGNIFICANCE AND USE
4.1 Tension tests provide reasonably accurate information with regard to the tensile strength of adhesives. Tensile strength data may be suitable for specification acceptance, service evaluation, manufacturing control, research, and development. Tension tests are not considered significant for applications differing from the test in rate, direction, and type of loading.
SCOPE
1.1 This test method covers the determination of the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens under defined conditions of preparation, conditioning, and testing. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.  
Note 1: An alternative test method for determining the tensile strength of adhesives is Test Method D897.  
1.2 The values stated in SI units are to be regarded as the 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
