1.1 本规范规定了便携式燃料容器（PFC）中用于汽油、煤油和柴油的火焰缓解装置（FMD）的性能要求，以供消费者再次使用。 1.2 汽油（红色）、柴油（黄色）和煤油（蓝色）PFC中的火焰缓解装置可保护容器开口，防止火焰传播到容器内的易燃燃油-空气混合物中。在与寒冷的环境条件和容器中的低液位相关的特殊情况下，容器中可能会形成易燃的燃油-空气混合物。已发布的报告中描述了这些情况和条件，例如Gardiner等人，2010年( 1. ), 2. 和论文，例如，Elias等人，2013年( 2. )，包括由ASTM F15.10技术委员会赞助和监督的研究。 1.3 本规范不涉及当PFC中的燃料浇到火上或附近或其他点火源导致这些外部蒸汽点燃或爆炸时，因PFC外部蒸汽点燃而导致的人身伤害或死亡危险。FMD不能防止与误用PFC相关的危险，导致外部蒸汽点火。 1.4 在试验之前，通过暴露于代表性燃料替代物CE25a和CE85a燃料以及其他预期条件，对火焰缓解装置进行化学调节。 1.5 在测试之前，通过反复插入和拆除燃料加油口对火焰缓解装置进行机械调节。 1.6 第一种试验方法确定，火焰缓解装置可以有效防止火焰传播到便携式燃料容器内的易燃丁烷-空气混合物中。丁烷-空气混合物是更可变燃料蒸汽的受控和可重复代理- 容器中的空气混合物。 1.7 第二种试验方法确定火焰缓解装置允许足够的燃料流速。 1.8 本规范规定了将被视为标准的国际单位制数值。括号中给出的值仅供参考。 1.9 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。 1.10 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。

1.1 This specification establishes performance requirements for flame mitigation devices (FMDs) in portable fuel containers (PFCs) for gasoline, kerosene, and diesel fuels intended for reuse by the consumer. 1.2 A flame mitigation device in gasoline (red), diesel (yellow), and kerosene (blue) PFCs protects the container openings from possible propagation of a flame into a flammable fuel-air mixture within the container. Formation of a flammable fuel-air mixture in the container can occur in special circumstances associated with cold ambient conditions and low liquid levels in the container. Delineations of those circumstances and conditions have been described in published reports, for example, Gardiner et al, 2010 ( 1 ), 2 and papers, for example, Elias et al, 2013 ( 2 ), including research sponsored and overseen by the ASTM F15.10 Technical Committee. 1.3 This specification does not address the hazard of injury or death caused by ignition of vapors external to the PFC when the fuel in the PFC is poured onto or near to a fire or other ignition source causing these external vapors to ignite or explode. An FMD does not prevent hazards associated with misuse of the PFC resulting in external vapor ignition. 1.4 The flame mitigation device is chemically conditioned by exposure to representative fuel surrogates CE25a and CE85a fuel and other expected conditions prior to the tests. 1.5 The flame mitigation device is mechanically conditioned by repeated insertions and removal of a fuel refueling spout prior to the tests. 1.6 The first test method establishes that the flame mitigation device can effectively prevent flame propagation into a flammable butane-air mixture inside the portable fuel container. The butane-air mixture is a controlled and repeatable proxy for the more variable fuel vapor-air mixture in the container. 1.7 The second test method establishes that the flame mitigation device is permitting adequate flow rates of fuel. 1.8 This specification states values in SI units which are to be regarded as the standard. The values given in parentheses are for information only. 1.9 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. 1.10 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.
