1.1 本规程涵盖从建筑物和相关结构中收集干燥油漆和其他涂层的样品。 1.2 本规程用于收集样品，以便随后在面积基础上（每取样面积的铅毫克数）或浓度基础上（所收集的每克干燥油漆的铅毫克量或所收集油漆样品中铅的质量百分比）测定铅。 1.3 本规程不涉及用于风险评估和其他铅危害活动的采样设计标准（即包括样本数量和位置的采样计划）。请参阅指南 E2115 或实践 e22.71/e22.71米 或 E3074/E3074M . 1.4 本规程包含解释性说明，不属于本规程强制性要求的一部分。 1.5 以国际单位制表示的数值应视为标准。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.6 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。 中给出了具体的警告声明 7.4.1.1 . 1.7 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 尽管本规程旨在收集建筑物和相关结构内及其周围的干燥油漆样品，以随后测定铅含量，但本规程也可用于收集其他结构的油漆样品，用于铅分析。 3. 5.2 与干燥油漆取样相关的可变性通常被认为远高于与油漆样品分析相关的可变性。因此，必须对样本采集进行适当控制，以产生具有代表性和有意义的样本。 5.3 这些样品的收集方式允许使用样品制备技术（如实践）进行后续消化 E1645 或 E1979 以及使用实验室分析技术如电感耦合等离子体原子发射光谱法（ICP-AES）测定铅（见试验方法 E3203 )或火焰原子吸收光谱法（FAAS）（见试验方法 E3193 ).

1.1 This practice covers the collection of samples of dried paint and other coatings from buildings and related structures. 1.2 This practice is used to collect samples for subsequent determination of lead on an area basis (milligrams of lead per area sampled) or concentration basis (milligrams of lead per gram of dried paint collected or mass percent of lead in the paint sample collected). 1.3 This practice does not address the sampling design criteria (that is, a sampling plan that includes the number and location of samples) that are used for risk assessment and other lead hazard activities. See Guide E2115 or Practices E2271/E2271M or E3074/E3074M . 1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.6 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. A specific warning statement is given in 7.4.1.1 . 1.7 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 Although this practice is intended for the collection of dried paint samples in and around buildings and related structures for the subsequent determination of lead content, this practice may also be used to collect paint samples from other structures for lead analysis. 3 5.2 The variability associated with the sampling of dried paint is generally considered to be far higher than the variability associated with the analyses of the paint specimens. Therefore, it is essential that sample collection be properly controlled to produce representative and meaningful samples. 5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1645 or E1979 and determination of lead using laboratory analysis techniques such as inductively coupled plasma atomic emission spectrometry (ICP-AES) (see Test Method E3203 ) or flame atomic absorption spectrometry (FAAS) (see Test Method E3193 ).
