1.1 本试验方法包括通过火焰原子吸收分光光度法（FAAS）测定空气中的颗粒物、通过擦拭和微真空吸尘的灰尘、油漆以及建筑物和相关结构中及其周围收集的土壤中的铅（Pb），该试验方法源自《试验方法》 D4185 和 E1613 。 1.2 铅（Pb）的灵敏度、检测限和最佳工作浓度见 表1 。 1.3 以国际单位制表示的数值应视为标准。本标准中不包括其他测量值。 1.3.1 例外-- 擦拭和微真空取样数据所示的SI和英寸磅单位应单独视为擦拭和微抽真空取样数据的标准( 14.4.2 和 14.4.3 )。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 本试验方法旨在与其他标准一起使用，这些标准涉及在评估或减轻建筑物和相关结构的铅危害期间获得的样本（空气中的颗粒物、擦拭和微真空吸尘产生的灰尘、干燥的油漆碎片和土壤）的收集和制备。 5.2 实验室分析在评估或缓解建筑物和相关结构的铅危害期间获得的样本，应符合规程 E1583 ，或应被具有管辖权的当局颁布的铅分析认可，或两者兼而有之。 注2: 在美利坚合众国，对含铅涂料活动期间收集的样品进行分析的实验室必须获得ISO/IEC 17025和环境保护局颁布的其他要求的认证。 5.3 该试验方法也可用于分析其他环境中的类似样品，如使用指南取样的废物的有毒特征提取物 E1908 以及使用美国环保局SW-846试验方法1311制备的用于分析的土壤和污泥。

1.1 This test method covers the determination of lead (Pb) in airborne particulate, dust by wipe and micro-vacuuming, paint, and soil collected in and around buildings and related structures by flame atomic absorption spectrophotometry (FAAS) and is derived from Test Methods D4185 and E1613 . 1.2 The sensitivity, detection limit, and optimum working concentration for lead (Pb) are given in Table 1 . 1.3 The values stated in SI units are to be regarded as standard. No other values of measurement are included in this standard. 1.3.1 Exception— The SI and inch-pound units shown for wipe and micro-vacuuming sampling data are to be individually regarded as standard for wipe and micro-vacuuming sampling data ( 14.4.2 and 14.4.3 ). 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 ====== 5.1 This test method is intended for use with other standards that address the collection and preparation of samples (airborne particulate, dusts by wipe and micro-vacuuming, dried paint chips, and soils) that are obtained during the assessment or mitigation of lead hazards from buildings and related structures. 5.2 Laboratories analyzing samples obtained during the assessment or mitigation of lead hazards from buildings and related structures shall conform to Practice E1583 , or shall be recognized for lead analysis as promulgated by authorities having jurisdiction, or both. Note 2: In the United States of America, laboratories performing analysis of samples collected during lead-based paint activities are required to be accredited to ISO/IEC 17025 and to other requirements promulgated by the Environmental Protection Agency (EPA). 5.3 This test method may also be used to analyze similar samples from other environments such as toxic characteristic extracts of waste sampled using Guide E1908 , and soil and sludge as prepared for analysis using U.S. EPA SW-846 Test Method 1311.
