1.1 本试验方法包括在0.010的浓度范围内测定汽油的总铅含量 g至0.10 g铅/美国加仑（2.5 mg/L至25mg/L）。该试验方法补偿了汽油成分的变化，且与烷基铅类型无关。 1.2 以克/美国加仑为单位的数值应视为美国的标准。请注意，在其他国家，可以首选其他单位。 1.3 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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体危险说明，请参见 7.6 和 7.8 . 1.4 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》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 本试验方法用于确保无铅汽油联邦法规（40 CFR第80部分）要求的微量铅的符合性。

1.1 This test method covers the determination of the total lead content of gasoline within the concentration range of 0.010 g to 0.10 g of lead/U.S. gal (2.5 mg/L to 25 mg/L). This test method compensates for variations in gasoline composition and is independent of lead alkyl type. 1.2 The values given in grams per U.S. gallon are to be regarded as the standard in the United States. Note that in other countries, other units can be preferred. 1.3 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 7.6 and 7.8 . 1.4 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 is used to ensure compliance of trace lead as required by federal regulation for lead-free gasoline (40 CFR part 80).
