摘要

1.1 This test method covers and is intended for use in the field by nontechnical people for the quantitative measurement of lead in unleaded gasoline in the range from 0.01 to 0.10 g Pb/U.S. gal (2.64 to 26.4 mg Pb/L). This method applies to all commercial gasolines and responds to all types of lead alkyls as well as to other organic and inorganic forms of lead.Note1—This test method is based on the use of the Mobil Lead Test Kit (Fig. 1).Note2—This test method is a screening test and is not to be used as a replacement for withdrawn Test Method D 3116, withdrawn Test Method D 3229, or Test Method D 3237.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3This 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 and health practices and determine the applicability of regulatory limitations prior to use.For specific warning statements, see Section 7.FIG. 1 Mobil Lead Test Kit ====== Significance And Use ======This test is used to determine trace quantities of lead in unleaded gasoline. Unwarranted amounts of lead may cause deposits in automotive pollution control equipment and poisoning of catalytic mufflers. 1.1本试验方法适用于非技术人员现场定量测量无铅汽油中的铅，范围为0.01至0.10 g Pb/美国加仑（2.64至26.4 mg Pb/L）。该方法适用于所有商用汽油，并对所有类型的烷基铅以及其他有机和无机形式的铅作出反应。笔记1-本测试方法基于Mobil铅测试套件的使用（图1）。笔记2-本试验方法为筛选试验，不得替代已撤销的试验方法D 3116，撤销试验方法D 3229，或试验方法D 3237.1.2以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。1.3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和健康实践，并确定监管限制的适用性。有关具体的警告声明，请参阅第7节。图1 Mobil铅测试套件====意义和用途======本试验用于测定无铅汽油中的微量铅。过量的铅可能会导致汽车污染控制设备中的沉积物和催化消声器中毒。展开▼
