1.1 This fire-test-response test method covers the determination under specified laboratory conditions of the combustibility of building materials. Materials passing this test are typically classified as noncombustible materials. 1.2 Limitations of this fire-test response test method are shown below. 1.2.1 This test method does not apply to laminated or coated materials. 1.2.2 This test method is not suitable or satisfactory for materials that soften, flow, melt, intumesce or otherwise separate from the measuring thermocouple. 1.2.3 This test method does not provide a measure of an intrinsic property. 1.2.4 This test method does not provide a quantitative measure of heat generation or combustibility; it simply serves as a test method with selected (end point) measures of combustibility. 1.2.5 The test method does not measure the self-heating tendencies of materials. 1.2.6 In this test method materials are not being tested in the nature and form used in building applications. The test specimen consists of a small, specified volume that is either (1) cut from a thick sheet;
