1.1 该火灾测试响应标准提供了一种标准测量方法，用于测量放置在四种标准基底之一上的香烟产生足够热量以继续燃烧的能力，从而可能导致床上用品或软垫家具着火。 1.2 这种方法有价值作为香烟点燃软垫家具的相对倾向的预测指标。 1.3 这种方法适用于沿烟草柱长度燃烧的香烟。 1.4 以国际单位制表示的数值应视为标准。 括号中给出的值仅供参考。 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，但其本身并未包含在实际火灾条件下对材料、产品和组件进行火灾危险或火灾风险评估所需的所有因素。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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 6. . 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 根据美国国家消防协会提供的统计数据，致命火灾中最常见的引发事件是香烟掉到床上或软垫家具上( 4. ). 试验方法 E1352 和 E1353 并且已经开发了测试NFPA 261和NFPA 260来评估软垫家具实体模型和部件对香烟点燃的易感性。颁布了联邦标准16 CFR第1632部分《床垫和床垫垫的易燃性标准》，以降低点燃的香烟点燃床垫和床垫的可能性。 注1: While测试方法 E1352 和 E1353 最初分别相当于NFPA 261和260，但现在已经不是这样了。 5.2 这种测试方法能够比较不同香烟设计的相对点燃强度。 5.3 在该程序中，试样将受到一系列实验室条件的影响。如果替换了不同的条件或改变了最终使用条件，则使用该试验可能无法预测所测火灾试验响应特性的定量变化。因此，定量结果仅适用于本程序中描述的火灾试验暴露条件。

1.1 This fire-test-response standard provides a standard measure of the capability of a cigarette, positioned on one of four standard substrates, to generate sufficient heat to continue burning and thus potentially cause ignition of bedding or upholstered furniture. 1.2 This method has value as a predictor of the relative propensity of a cigarette to ignite upholstered furnishings. 1.3 This method is applicable to cigarettes that burn along the length of a tobacco column. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 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 6 . 1.7 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 The most common initiating event in a fatal fire is the dropping of a cigarette onto a bed or piece of upholstered furniture, according to statistics provided by the National Fire Protection Association ( 4 ). Test Methods E1352 and E1353 and tests NFPA 261 and NFPA 260 have been developed to evaluate the susceptibility of upholstered furniture mock-ups and components to ignition by cigarettes. Federal Standard 16 CFR Part 1632, Standard for the Flammability of Mattresses and Mattress Pads, was promulgated to reduce the likelihood that mattresses and mattress pads would ignite from a lighted cigarette. Note 1: While Test Methods E1352 and E1353 were originally equivalent to NFPA 261 and 260, respectively, this is no longer the case. 5.2 This test method enables comparison of the relative ignition strength of different cigarette designs. 5.3 In this procedure, the specimens are subjected to a set of laboratory conditions. If different conditions are substituted or the end use conditions are changed, it may not be possible, using this test, to predict quantitative changes in the fire test response characteristics measured. Therefore, the quantitative results are valid only for the fire test exposure conditions described in this procedure.
