1.1本标准规定了当用作甲板行走面时，评估甲板材料火灾试验响应特性的方法。在试验条件下，规定的火灾暴露旨在确定当暴露于模拟甲板下燃烧的可燃物的燃烧器火焰时，甲板材料的热释放速率和热分解模式。 2. 1.2以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，每个系统应相互独立使用。 将两个系统的值结合起来可能会导致不符合标准。 1.3本标准用于测量和描述甲板材料在受控条件下对热量和火焰的响应，但其本身并不包括实际火灾条件下甲板材料火灾危险或火灾风险评估所需的所有因素。 1.4 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防火测试本身具有危险性。在进行这些测试时，应采取适当的人员和财产保护措施。 ====意义和用途====== 5.1本试验方法通过评估甲板材料对与位于甲板材料下方的火源相关的火灾危险的反应来确定甲板材料的适用性。

1.1 This standard prescribes a method to assess the fire-test response characteristics of deck materials when used as the walking surface of a deck. The prescribed fire exposure is intended, under test conditions, to determine the heat release rate and the thermal decomposition modes of decking materials when exposed to a burner flame simulating combustibles burning beneath a deck. 2 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems has the potential to result in non-conformance with the standard. 1.3 This standard is used to measure and describe the response of deck materials 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 deck materials 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 is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. ====== Significance And Use ====== 5.1 This test method addresses the suitability of deck materials by assessing their response to fire hazards associated with sources of flame located beneath the deck material.
