1.1 本试验方法旨在作为筛选试验，以确定涂料中的固体含量是否超过0.06 % 领导所述测试可以区分0.05和0.06 %. 结果大于0.05的油漆 % 应使用测试方法对铅进行定量分析 D3335 . 该试验方法比试验方法提供了更明确、更可靠的筛选试验 D3618 . 1.2 如果对样本大小和试剂量进行了适当稀释和调整，则没有理由相信本试验方法无法测定更高水平的铅。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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。 ====意义和用途====== 4.1 美国现行法规将消费类油漆产品中的铅含量限制在0.06以下 % 基于总固体。本试验方法提供了一种快速筛选涂料的方法，以确定是否符合这些法规。可以调整试验方法，以满足对铅含量有不同限制的法规。

1.1 This test method is intended as a screening test to determine if the solids in a paint contain more than 0.06 % lead. The test described can differentiate between 0.05 and 0.06 %. Paints giving a result greater than 0.05 % should be analyzed quantitatively for lead using Test Method D3335 . This test method provides a more definitive and reliable screening test than Test Method D3618 . 1.2 There is no reason to believe that higher levels of lead could not be determined by this test method provided that appropriate dilutions and adjustments in specimen size and reagent quantities are made. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. ====== Significance And Use ====== 4.1 Current U.S. regulations restrict the amount of lead that may be present in consumer paint products to less than 0.06 % based on the total solids. This test method provides a rapid means for screening paints to determine compliance with those regulations. The test method may be adjusted to meet regulations with a different limit on lead content.
