1.1 This fire-test-response standard covers a procedure for measuring fire properties associated with flammable behavior of surface finishes used on noncombustible substrates (Note 1). In particular, these include surface finishes intended for use as surfacing materials and ceiling veneers including any adhesives used to fasten the veneers to ceilings, paints, and exposed treatment of insulating materials. Note 1: This test method was originally developed to closely follow the test procedure of IMO Resolution A.653(16) (1).2 ISO 5658-2 also describes similar test equipment. The test procedure used by IMO for regulation of surface finishes is IMO 2010 FTP Code Part 5 (2), which has replaced IMO Resolution A.653(16). 1.2 Tests performed according to this test method are intended to yield fire properties that, when appropriately interpreted, are potentially useful to select materials and surface treatments that will limit the rapid growth and spread of fire. 1.3 This test method requires a specific range of specimen radiant thermal exposure for measuring fire properties. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 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. For specific hazard statements, see Section 7. 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.
