1.1本耐火试验响应试验方法涵盖在规定的实验室条件下测定建筑材料的燃烧特性。 1.2本火灾试验响应试验方法的局限性如下所示。 1.2.1本试验方法不适用于层压或涂层材料。 1.2.2本试验方法不适用于软化、流动、熔融、膨胀或以其他方式与测量热电偶分离的材料。 1.2.3本试验方法不提供固有特性的测量。 1.2.4本试验方法未提供热量产生或燃烧性的定量测量；它只是作为一种测试方法，具有选定的（终点）燃烧性测量。 1.2.5本试验方法不测量材料的自热倾向。 1.2.6在本试验方法中，材料未按建筑应用中使用的性质和形式进行试验。试样由一个小的规定体积组成，该体积为 (1) 从厚纸上切下； (2) 由多种厚度的薄板组装而成；或 (3) 如果由颗粒状粉末或松散纤维材料组成，则放置在容器中。 1.2.7本试验方法的结果适用于特定的试验装置和试验条件，并且当对以下一项或多项进行更改时，结果可能会发生变化: (1) 试样的尺寸、形状和排列； (2) 有机物含量的分布； (3) 暴露温度； (4) 空气供应； (5) 热电偶的位置。 1.3本试验方法参考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）不应视为本试验方法的要求。 1.4以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.5本试验方法在技术上等同于ISO 1182。 1.6 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并不包含火灾所需的所有因素- 实际火灾条件下材料、产品或组件的危险或火灾风险评估。 1.7 火灾测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.8 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。 ====意义和用途====== 虽然没有复制实际的建筑火灾暴露条件，但本试验方法将有助于指示那些不起助于燃烧或向环境火灾中添加可观热量的材料。 本试验方法不适用于层压或涂层材料。 该试验方法在技术上等同于ISO 1182。

1.1 This fire-test-response test method covers the determination under specified laboratory conditions of combustion characteristics of building 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 meeasuring 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 This 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 aplications. The test specimen consists of a small, specified volume that is either (1) cut from a thick sheet; (2) assembled from multiple thicknesses of thin sheets; or (3) placed in a container if composed of grarnular powder or loose fiber materials. 1.2.7 Results from this test method apply to the specific test apparatus and test conditions and are likely to vary when changes are made to one or more of the following: (1) the size, shape, and arrangement of the specimen; (2) the distribution of organice content; (3) the exposure temperature; (4) the air supply; (5) the location of thermocouples. 1.3 This test method 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 test method. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.5 This test method is technically equivalent to ISO 1182. 1.6 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. 1.7 FIre testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.8 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. ====== Significance And Use ====== While actual building fire exposure conditions are not duplicated, this test method will assist in indicating those materials which do not act to aid combustion or add appreciable heat to an ambient fire. This test method does not apply to laminated or coated materials. This test method is technically equivalent to ISO 1182.
