本文件规定了用于测定汽油铅含量在2.5 mg/l至10,0 mg/l范围内的原子吸收光谱测试方法。该测试方法与铅烷基类型无关。 注1附件A描述了一种替代方法，但是对于测定汽油中铅含量在3.0mg/l至10,0mg/l范围内的精度较差。该方法也与铅烷基类型无关。 注2为本文件的目的，术语“％（V/V）”用于表示体积分数。 警告 - 使用本文档可能涉及危险材料，操作和设备。本标准并不旨在解决与其使用相关的所有安全问题。本标准用户有责任建立适当的安全和健康实践，并在使用前确定法规限制的适用性

This document specifies an atomic absorption spectrometric test method for the determination of the lead content of petrol in the range 2,5 mg/l to 10,0 mg/l. This test method is independent of the lead alkyl type. NOTE 1 Annex A describes an alternative procedure but with a poorer precision for the determination of the lead content of petrol in the range 3,0 mg/l to 10,0 mg/l. This procedure is also independent of the lead alkyl type. NOTE 2 For the purposes of this document, the term "% (V/V)" is used to represent the volume fraction. WARNING - The use of this document may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
