ASTM E1740-07a PDF

1.1 This fire-test-response test method covers determination of the ignitability and heat release rate of composites consisting of a wallcovering, a substrate, and all laminating adhesives, coatings, and finishes. Heat release information cannot be used alone to evaluate the flammability of wallcoverings. The data are intended to be used for modeling or with other data to evaluate a material.

1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant radiant heat flux of 35 kW/m ². Heat release data at different heating fluxes are also obtained by this test method. The specimen is oriented horizontally, and a spark ignition source is used.

1.3 The fire-test-response characteristics are determined using the apparatus and procedures described in Test Method E 1354.

1.4 The tests are conducted on bench-scale specimens combining the components used in the actual installation.

1.5 The values stated in SI units are to be regarded as the standard. See IEEE/ASTM SI-10.

1.6 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be used in conducting these tests. This test method potentially involves hazardous materials, operations, and equipment.

1.7 This standard is used to measure and describe 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.

1.8 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. This test method may involve hazardous materials, operations, and equipment. Specific information about hazard is given in Section 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 and health practices and determine the applicability of regulatory limitations prior to use.
