The test methods  include simulated fire exposure to the outside of the roof coverings, and,  where applicable, a determination as to whether the fire performance characteristics  of the roof coverings will be adversely affected by prolonged exposure to  rain. These test methods measure the surface spread of flame and the ability of the roof covering material or system to resist fire  penetration from the exterior to the underside of a roof deck under the conditions  of exposure. These test methods also provide criteria to determine if the roof covering material will develop flying burning material, identified as flying brands, when subjected to a 12-mph [5.3-m/s] wind during the simulated fire exposure tests. These test methods do not necessarily illustrate the expected performance of roof coverings under all actual fire conditions,  but they do provide a basis for comparing roof covering materials when subjected  to fire sources that are described herein. These test methods do not provide any basis for determining the fire resistance characteristics when exposed to a fire originating  in the building to which the roofing material is applied. The test methods described herein involve calibrating the test equipment using a calibration deck inclined at a slope of 5 in. per horizontal ft (0.416:1). The tests described herein are performed on test  decks inclined at slopes up to and including 5 in. per horizontal ft. The  severity of the test exposure decreases as the slope of the test deck decreases below 5 in. per horizontal ft.1.1 This fire-test-response standard covers the measurement of the relative fire characteristics of roof coverings under simulated fire originating outside the building. It is applicable to roof coverings intended for installation on either combustible or noncombustible decks when applied as intended for use. The following test methods are included:1.1.1 Intermittent flame exposure test.1.1.2 Spread of flame test.1.1.3 Burning brand test.1.1.4 Flying brand test.1.1.5 Rain test.1.2 Three classes of fire test exposure are described:1.2.1 Class A Tests are applicable to roof coverings that are effective against severe test exposure, afford a high degree of fire protection to the roof deck, do not slip from position, and do not present a flying brand hazard.1.2.2 Class B Tests are applicable to roof coverings that are effective against moderate test exposure, afford a moderate degree of fire protection to the roof deck, do not slip from position, and do not present a flying brand hazard.1.2.3 Class C Tests are applicable to roof coverings that are effective against light test exposure, afford a light degree of fire protection to the roof deck, do not slip from position, and do not present a flying brand hazard.1.3 The values stated in inch-pound units shall be regarded as the standard. Values given in brackets are for information only.1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled laboratory 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.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 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables an......【中国标准分类号】: P16;Q70【国际标准分类号】: 13_220_50; 91_060_20【页数】: 13P.;A4【正文语种】:
