1.1 该火灾测试响应标准提供了放置在基底上的大麻/大麻预卷产生足够热量以继续燃烧并因此潜在地导致床上用品或软垫家具着火的概率的标准测量。 1.2 本试验方法应适用于通过燃烧供个人吸入的预卷装置，并含有来自任何类型大麻植物（即大麻/大麻）的干燥草药材料。为了简洁起见，术语“大麻”此后应用于指任何类型的大麻植物（大麻/大麻）。 1.3 本试验方法应适用于沿大麻预卷柱长度燃烧的预卷。 1.4 本试验方法不适用于本标准范围之外的灌注预卷。1.5 卷前准备和取样应根据实践进行 D8343/D8343M . 1.6 单位- 以SI单位或美国习惯单位（USC单位）表示的值应单独视为标准值。每个系统中陈述的值可能不完全等同；因此，每个系统应独立使用。合并两个系统的值可能导致不符合标准。公制单位将被声明为标准单位，USC单位将显示在相对于公制单位的括号中。 1.7 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 根据NFPA提供的统计数据，致命火灾中最常见的引发事件之一是将吸烟材料（如预卷）掉落到床或一件软垫家具上。试验方法 E1352 和 E1353 已经开发了NFPA 261和NFPA 260来评估软垫家具模型和部件对香烟点燃的敏感性（类似于预卷）。联邦标准16 CFR 1632的颁布是为了降低床垫和床垫垫被点燃的吸烟材料点燃的可能性。测试方法的研究(NIST 851-2)已经发现，滤纸基材可用于用多层普通滤纸代替织物/衬垫组件，在测量点火强度方面显示出系统的进展。此外，在滤纸基底上具有高百分比全长燃烧的吸烟材料(NIST 1436)产生足够的热量以保持燃烧，因此比具有较低百分比全长燃烧的吸烟材料更可能点燃软家具。 5.2 在该测试方法中，预辊经受一组实验室条件。如果替代不同的条件或改变最终使用条件，则可能无法使用这种测试方法来预测火灾测试响应的定量变化。因此，定量结果仅对本试验方法所述的火灾试验暴露条件有效。卷前准备和取样对于确保对结果的影响最小非常重要。应通过实践进行准备 D8343/D8343M . 5.3 该测试方法概述了预卷中大麻草药材料的水分含量。确定所用大麻药草材料的水分含量将更多地了解水分对预卷在点燃时实现全长燃烧的概率的影响。 5.4 来自该测试方法的数据可以帮助推断一组预卷样品在保持不动的情况下是否会保持点火。 5.5 该测试方法可用于确定大麻/大麻预卷全长烧伤的概率。

1.1 This fire-test-response standard provides a standard measure of the probability of a cannabis/hemp pre-roll positioned on a substrate to generate enough heat to continue burning and thus potentially cause ignition of bedding or upholstered furniture. 1.2 This test method shall be applicable to pre-roll units that are intended for personal inhalation by means of combustion and contain dried herbal material from any type of a cannabis plant, that is, cannabis/hemp. For the sake of brevity, the term “cannabis” shall be used henceforth to refer to any type of cannabis plant (cannabis/hemp). 1.3 This test method shall be applicable to pre-rolls that burn along the length of a cannabis pre-roll column. 1.4 This test method shall not be applicable to infused pre-rolls, which are outside the scope of this standard. 1.5 Pre-roll preparation and sampling shall be made using Practice D8343/D8343M . 1.6 Units— The values stated in either SI units or United States Customary units (USC units) are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Metric units will be stated as standard and USC units will be shown in brackets relative to the metric units. 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. 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 According to statistics provided by the NFPA, one of the most common initiating events in a fatal fire is the dropping of a smoking material, such as a pre-roll, onto a bed or a piece of upholstered furniture. Test Methods E1352 and E1353 and NFPA 261 and NFPA 260 have been developed to evaluate the susceptibility of upholstered furniture mock-ups and components to ignition by cigarettes (similarly for pre-rolls). Federal Standard 16 CFR 1632 was promulgated to reduce the likelihood that mattresses and mattress pads would ignite from a lighted smoking material. Research of test methods (NIST 851-2) has found that filter paper substrates can be used to replace the fabric/padding assembly with multiple layers of common filter paper showing a systematic progression in measuring ignition strength. Additionally, smoking materials with high percentages of full-length burns on filter paper substrates (NIST 1436) generate enough heat to keep burning and thus are more likely to ignite soft furnishings than smoking materials with lower percentages of full-length burns. 5.2 In this test method, the pre-rolls 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 to use this test method to predict quantitative changes in the fire test response. Therefore, the quantitative results are valid only for the fire test exposure conditions described in this test method. Pre-roll preparation and sampling are very important to ensure minimal impact on results. Preparation shall be made using Practice D8343/D8343M . 5.3 This test method outlines the moisture content of cannabis herbal material in the pre-roll. Determining the moisture content of cannabis herbal material used will shed more light on the effects of moisture on the probability of a pre-roll to achieve a full-length burn when ignited. 5.4 The data from this test method can help extrapolate whether a sample set of pre-rolls would maintain ignition if remained untouched. 5.5 This test method can be used to determine the probability of a full-length burn on cannabis/hemp pre-roll.
