Standard Test Method for Tensile and Tensile Adhesion Properties of Rigid Cellular Plastics

ABSTRACT
This test method establishes standard procedure for determining the tensile and tensile adhesion properties of rigid cellular plastics in the form of test specimens of standard shape under defined conditions of temperature, humidity, and testing machine speed. Tensile properties shall be measured using any of three types of specimens: Type A shall be the preferred specimen in those cases where enough sample material exists to form the necessary specimen; Type B shall be the preferred specimen when only smaller specimens are available, as in sandwich panels, etc.; Type C shall be the preferred specimen for the determination of tensile adhesive properties of a cellular plastic to a substrate as in a sandwich panel or the bonding strength of a cellular plastic to a single substrate. This test method requires the use of the following apparatuses: a constant-rate-of-crosshead-movement type testing machine; self-aligning type grips for holding test specimens; an extension indicator; and a lathe specimen cutter.
SCOPE
1.1 This test method covers the determination of the tensile and tensile adhesion properties of rigid cellular materials in the form of test specimens of standard shape under defined conditions of temperature, humidity, and testing machine speed.  
1.2 Tensile properties shall be measured using any of three types of specimens:  
1.2.1 Type A shall be the preferred specimen in those cases where enough sample material exists to form the necessary specimen.  
1.2.2 Type B shall be the preferred specimen when only smaller specimens are available, as in sandwich panels, etc.  
1.2.3 Type C shall be the preferred specimen for the determination of tensile adhesive properties of a cellular plastic to a substrate as in a sandwich panel (top and bottom substrate) or the bonding strength of a cellular plastic to a single substrate.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
Note 1: There is no known ISO equivalent to this test method.  
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.

ASTM D1621-16(2023)(Test Method)
Standard Test Method for Compressive Properties of Rigid Cellular Plastics

SIGNIFICANCE AND USE
4.1 This test method provides information regarding the behavior of cellular materials under compressive loads. Test data is obtained, and from a complete load-deformation curve it is possible to compute the compressive stress at any load (such as compressive stress at proportional-limit load or compressive strength at maximum load) and to compute the effective modulus of elasticity.  
4.2 Compression tests provide a standard method of obtaining data for research and development, quality control, acceptance or rejection under specifications, and special purposes. The tests cannot be considered significant for engineering design in applications differing widely from the load - time scale of the standard test. Such applications require additional tests such as impact, creep, and fatigue.  
4.3 Before proceeding with this test method, reference shall be made to the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or a combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply.
SCOPE
1.1 This test method describes a procedure for determining the compressive properties of rigid cellular materials, particularly expanded plastics.  
1.2 The values stated in SI units are to be regarded as the standard. The values 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.
Note 1: This test method and ISO 844 are technically equivalent.  
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.

ASTM D5672/D5672M-22(Test Method)
Standard Test Method for Testing Flexible Cellular Materials Measurement of Indentation Force Deflection Using a 25-mm [1-in.] Deflection Technique

SIGNIFICANCE AND USE
4.1 The 25-mm [1-in.] deflection IFD method is recommended for production screening and quality control on full size cushions only.  
4.2 Applicable cushion thicknesses to be tested by this test method are only those listed in this test method. Further research and development are required before this test method is applicable to other cushion thicknesses.  
4.3 This test method is designed to give a value approximating the 25 % IFD on a 100-mm [4-in.] thick piece of foam when the actual specimen thickness tested is within the ranges listed in the test method. In case of disagreement, the referee method is the IFD procedure in Test Methods D3574, Test B1. The user of this test method shall establish the correlation between this test method and the referee method.
SCOPE
1.1 This test method covers a screening type quality control test used to determine if flexible polyurethane foam cushions are within the specified grade range for firmness.  
1.2 This test method is limited to foams with thicknesses that are 75 mm [3 in.] or greater.  
1.3 This test method is based on the fact that the traditional industry standard thickness for Indentation Force Deflection (IFD) is 100 mm [4 in.], and the traditional percent deflection for IFD acceptance and product planning is 25 %. With respect, then, to these traditional industry conventions, a 25 % deflection on a 100-mm [4-in.] cushion would be 25 mm [1 in.]. Thus, deflecting standard cushions (of proper 100 mm thickness) 25 mm [1 in.] provides a quick way to determine if the flexible polyurethane foam is within the specified grade range for 25 % IFD.  
1.4 Cushion thicknesses less than 75 mm [3 in.] shall not be tested for IFD using this test method.  
1.5 This test method is intended to provide a quick and simple method to screen flexible polyurethane foams for determination of its firmness grade.  
1.6 Units—The values stated in U.S. Customary or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.7 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.
Note 1: This test method and ISO 2439 address the same subject matter, but differ in technical content.  
1.8 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 Horizontal Burning Characteristics of Cellular Polymeric Materials

SIGNIFICANCE AND USE
5.1 This test method provides a means of measuring the time and extent of burning for cellular polymeric materials. It also provides a means of measuring burning rates for materials that continue to burn past the specified gage marks.  
5.2 This test method provides a means of comparing the burning characteristics of materials of like thickness density, cell size, and skin irregularities, including the effect of falling particles of cellular polymeric materials. It is suitable for quality control, specification acceptance, and for research and development. Examples include filled or reinforced, rigid or flexible, or cut or formed materials  
5.3 In this test method, the specimens are subjected to one or more specific sets of laboratory fire test exposure conditions. If different test conditions are substituted or if the anticipated end-use conditions are changed, it is not always possible from this test method to predict changes in the performance characteristics measured. Therefore, the results are strictly valid only for the fire test exposure conditions described in this procedure.  
5.4 This test method is not intended to be a criterion for fire hazard. The fire hazard created by materials depends upon the form and end use of the material. Assessment of fire hazard includes, but is not limited to, many factors such as flame spread, burning rate, ease of ignition, fuel contribution, heat evolution, products of combustion, and others.
SCOPE
1.1 This fire-test-response standard contains a test method for small-scale laboratory procedures to be used to determine the relative rate of burning and the extent and time of burning of horizontally oriented cellular polymeric materials having a density less than 250 kg/m3.  
1.2 The results are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application. The final acceptance of the material is dependent upon its use in the end-product that conforms with the standards applicable to such end-product.  
1.3 The classification system described in the Appendix X1 is intended for quality assurance and the preselection of component materials for products.  
1.4 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.5 The values stated in SI units are to be regarded as 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. For a specific hazard statement, see 6.1.1.  
1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
Note 1: This test method is equivalent to ISO 9772.  
1.8 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 D3675-22(Test Method)
Standard Test Method for Surface Flammability of Flexible Cellular Materials Using a Radiant Heat Energy Source

SIGNIFICANCE AND USE
5.1 This test method is intended for use when measuring surface flammability of flexible cellular materials exposed to fire. The test method provides a laboratory test procedure for measuring and comparing the surface flammability of materials when exposed to a prescribed level of radiant heat energy. The test is conducted using specimens that are representative, to the extent possible, of the material or assembly being evaluated. For example, if an assembly is required to be tested, such specimens shall replicate the type and thickness of all the layers present in the assembly being evaluated.  
5.2 The rate at which flames will travel along surfaces depends upon the physical and thermal properties of the material, product, or assembly under test, the specimen mounting method and orientation, the type and level of fire or heat exposure, the availability of air, and properties of the surrounding enclosure. (1-6)4, 5  
5.3 Test Method E162 is a generic version of this test method, using an apparatus that is substantially the same as the one used in this test method. However, Test Method E162 is normally intended for application to specimens other than flexible cellular materials.  
5.3.1 The pilot burner in this test method is different from the pilot burner in Test Method E162.  
5.4 In this procedure, the specimens are subjected to one or more specific sets of laboratory fire test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure.  
5.5 If the test results obtained by this test method are to be considered as part of an overall assessment of fire hazard in a building or structure, then the criteria, concepts and procedures incorporated into Guide E1546 shall be taken into consideration.
SCOPE
1.1 This is a fire test response standard.  
1.2 This test method describes the measurement of surface flammability of flexible cellular materials.  
1.3 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not, by itself, incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
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 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.6 Specific information about hazards is given in Section 7.
Note 1: There is no known ISO equivalent to this standard.  
1.7 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units, in parentheses, are for information only and are approximations (see also IEEE/ASTM SI-10).

Standard Specification for Flexible Cellular Materials Made From Polyolefin Plastics

ABSTRACT
This specification applies to flexible closed-cell materials made from polyolefin plastics and blends of polyolefin plastics. Two types of flexible, closed-cell polyolefin foams are covered: type I - closed cell foams made with polyolefin plastics and either chemically or radiation crosslinked, and type II - closed cell foams made with polyolefin plastics that are non-crosslinked. Cellular polyolefin foams furnished under this specification shall be manufactured from any resin or blend of resins that are members of the polyolefin family together with added compounding materials. Unless otherwise specified, the color of cellular polyolefin foams shall be natural.
SCOPE
1.1 This specification applies to flexible closed-cell materials made from polyolefin plastics and blends of polyolefin plastics as defined in Section 3.  
1.2 Extruded or molded shapes too small to permit the cutting of standard test specimens are difficult to classify or test by standard test methods and will usually require special testing procedures or the use of standard test sheets.  
1.3 In case of conflict between the provisions of this specification and those of detailed specifications for a particular product, the latter shall take precedence. These detailed specifications for the flexible closed-cell polyolefin plastic foams shall state the particular test or tests desired.  
1.4 In cases involving referee decisions, SI units shall be used.  
1.5 This specification does not contain test procedures or values for all the suffix letters listed in Table 1 and Table 2. Where the procedure is not described in this specification or special limits are desired, or both, the test procedures and values must be arranged between the purchaser and the supplier.    
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
Note 1: There is no known ISO equivalent to this standard.  
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.
