1.1 This fire-test-response standard describes the measurement of surface flammability of materials. It is not intended for use as a basis of ratings for building code purposes (see Appendix X1).

1.2 The values stated in pound-inch units are to be regarded as the standard. The values in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use.

1.5 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 7.

Note 1—There is no similar or equivalent ISO standard.
