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

1.2This 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 initial test heat flux of 35 kW/m². Heat release data at different heat fluxes are also obtained by this test method. The specimen is oriented horizontally, and a spark ignition source is used.

1.3The fire-test-response characteristics are determined using the apparatus and procedures described in Test Method E1354.

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

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

1.6Fire 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.

1.7This 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.

1.8Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. Specific information about hazard is given in Section 6.

1.9This 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.

1.10This 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.
