1.1本火灾测试响应标准涵盖了在建筑物外部模拟火灾下屋顶覆盖物相对火灾特性的测量。当按预期用途使用时，适用于安装在易燃或不易燃甲板上的屋顶覆盖物。包括以下试验方法: 1.1.1间歇性火焰暴露试验。 1.1.2火焰蔓延试验。 1.1.3燃烧品牌测试。 1.1.4飞行品牌测试。 1.1.5淋雨试验。 1.2描述了三类火灾试验暴露: 1.2.1 A类试验适用于有效抵抗严重试验暴露、对屋顶板提供高度防火保护、不会从位置滑落且不会造成飞行危险的屋顶覆盖物。 1.2.2 B类试验适用于有效抵抗中等试验暴露、对屋顶甲板提供中等程度防火、不会从位置滑落且不会造成飞行危险的屋顶覆盖物。 1.2.3 C类试验适用于有效抵抗光照试验暴露、为屋顶甲板提供轻度防火保护、不会从位置滑落且不会造成飞行危险的屋顶覆盖物。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.4 本标准用于测量和描述材料、产品或组件在受控实验室条件下对热量和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.5本标准的文本引用了提供解释信息的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。

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 and figures, shall not be considered as requirements of this standard.
