1.1 本规范确立了确定便携式燃料容器（PFC）和其他类型便携式容器的儿童电阻的公认要求，这些容器供消费者用于持有、储存和运输汽油、煤油和柴油等液体燃料。 1.1.1 规范中定义了“便携式燃料容器” F852 包括汽油、煤油或柴油容器，以及与便携式汽油、煤油或柴油容器一起使用或在便携式汽油、煤油或柴油容器上使用的喷嘴、盖和其他闭合机构和组件。 1.1.2 本规范也适用于单独出售的与燃料容器一起使用或在燃料容器上使用的喷嘴、盖或其他闭合机构。 1.1.3 本规范不包括符合规范的一次性使用便携式应急燃料容器 F2874 . 1.2 本标准仅涉及闭合循环后儿童电阻（CR）装置的有效性，但未涉及闭合有效性: 1.2.1 在高温或低温下， 1.2.2 聚合物热老化后， 1.2.3 暴露在阳光下后， 1.2.4 暴露于预期燃料后，以及 1.2.5 身体虐待后，如跌落或撞击。 注1: 请看 附录X2 有关这些豁免的更多信息。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 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。 1.5 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 recognized requirements for determining the child resistance of portable fuel containers (PFCs) and other types of portable containers intended for use by consumers to hold, store, and transport liquid fuels such as gasoline, kerosene, and diesel. 1.1.1 “Portable Fuel Container” is defined in Specification F852 and includes the receptacle for gasoline, kerosene, or diesel fuel as well as spouts, caps, and other closure mechanisms and components for use with or on portable gasoline, kerosene, or diesel receptacles. 1.1.2 This specification is also applicable to spouts, caps, or other closure mechanisms sold separately for use with or on a fuel container. 1.1.3 This specification does not cover one-time use portable emergency fuel containers conforming to Specification F2874 . 1.2 This standard addresses the effectiveness of the child resistance (CR) device only after closure cycling, but does not address closure effectiveness: 1.2.1 When at high or low temperatures, 1.2.2 After thermal aging of polymers, 1.2.3 After exposure to sunlight, 1.2.4 After exposure to intended fuels, and 1.2.5 After physical abuses, such as drops or impacts. Note 1: Please see Appendix X2 for additional information on these exemptions. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. 1.5 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.
