1.1 本防火测试响应标准涵盖了测量与不燃基材表面饰面易燃行为相关的防火性能的程序( 注1 ). 特别是，这些包括用作表面材料的表面处理和天花板饰板，包括用于将饰板固定到天花板上的任何粘合剂、油漆和绝缘材料的外露处理。 注1: 该测试方法最初是为了严格遵循IMO决议A.653（16）的测试程序而开发的 ( 1. ) . 2. ISO 5658-2也描述了类似的测试设备。IMO用于调节表面光洁度的试验程序是IMO 2010 FTP规范第5部分 ( 2. ) ，取代了海事组织第A.653（16）号决议。 1.2 根据本试验方法进行的试验旨在产生火灾特性，当适当解释时，这些特性可能有助于选择限制火灾快速蔓延的材料和表面处理。 1.3 本试验方法需要特定范围的试样辐射热暴露，以测量火灾特性。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 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。 1.6 防火测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.7 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、健康和环境实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅第节 7. . 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法提供了一种评估表面处理材料易燃性能的方法。 5.2 将关注的表面光洁度样本安装在预期使用的支撑材料上，并经受受控的显著辐射通量暴露。 5.3 所有试样在垂直面上安装时进行测试。 5.4 以下表面暴露于试验中: 5.4.1 在暴露的一侧或两侧测试具有表面单板、织物或涂漆饰面的试样。 5.4.2 天花板饰面材料应在下部外露表面上进行测试。 5.4.3 对于穿孔和空气支撑的天花板饰面材料，还应在材料的背面（上部）进行测试。 5.4.4 在上部外露表面上测试地板饰面和地板材料。 5.4.5 在暴露在空气中的表面上测试绝缘材料上的保护膜或饰面。 5.5 本试验方法提供了与试验样品易燃性相关的燃烧特性。这些包括可燃性、持续燃烧的热暴露、灭火时的临界通量以及在不同通量暴露条件下的热释放行为。 5.6 本试验方法未提供: 5.6.1 由背衬材料（非测试材料）支撑的表面饰面材料的防火性能的完整信息。 5.6.2 当用于测试厚度以外的其他厚度时，有关表面光洁度材料的完整信息。 5.6.3 使用防火性能测量作为测试样本火灾风险或危险分类的测量方法。

1.1 This fire-test-response standard covers a procedure for measuring fire properties associated with flammable behavior of surface finishes used on noncombustible substrates ( Note 1 ). In particular, these include surface finishes intended for use as surfacing materials and ceiling veneers including any adhesives used to fasten the veneers to ceilings, paints, and exposed treatment of insulating materials. Note 1: This test method was originally developed to closely follow the test procedure of IMO Resolution A.653(16) ( 1 ) . 2 ISO 5658-2 also describes similar test equipment. The test procedure used by IMO for regulation of surface finishes is IMO 2010 FTP Code Part 5 ( 2 ) , which has replaced IMO Resolution A.653(16). 1.2 Tests performed according to this test method are intended to yield fire properties that, when appropriately interpreted, are potentially useful to select materials and surface treatments that will limit the rapid growth and spread of fire. 1.3 This test method requires a specific range of specimen radiant thermal exposure for measuring fire properties. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7 . 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method provides a means for evaluation of the flammable performance of surface finish materials. 5.2 A specimen of the surface finish of concern is mounted on the support material contemplated for use and subjected to a controlled significant radiant-flux exposure. 5.3 All specimens are tested while mounted in a vertical plane. 5.4 The following surfaces are exposed to test: 5.4.1 Specimens having surface veneers, fabrics, or painted finishes are tested on one or both exposed sides. 5.4.2 Ceiling finish materials shall be tested on the lower exposed surface. 5.4.3 For ceiling finish materials which are perforated and air backed, tests also shall be conducted on the back (upper) surface of the material. 5.4.4 Floor finish and flooring materials are tested on the upper exposed surface. 5.4.5 Protective membranes or finishes on insulation materials are tested on the air-exposed face or faces. 5.5 This test method provides fire properties that relate to the flammability of the specimens tested. These include ignitability, heat exposure for continued burning, critical flux at extinguishment, and heat-release behavior under varying flux-exposure conditions applied. 5.6 This test method does not provide: 5.6.1 Full information on fire properties of surface-finish materials supported by backing materials other than those tested. 5.6.2 Full information on surface-finish materials when used in other thicknesses than those tested. 5.6.3 Methods for using the fire property measurements as a measure for classifying the fire risk or hazard of the specimens tested.
