1.1 本规程涵盖使用取芯和铲取方法从建筑物和相关结构周围区域采集裸土样本。 1.2 这种做法可能不适合从铺设或以其他方式覆盖草地、覆盖物或类似物的区域收集土壤样本。请参阅指南 E2115 或实践 e22.71/e22.71米 或 E3074/E3074M . 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）。 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。 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 尽管本规程旨在从建筑物内及周围的裸露区域采集土壤样本，但本规程也可用于从其他区域和环境采集土壤样本。 5.2 这种做法将土壤收集限制在土壤表面约1.5厘米（0.6英寸）的顶部。 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 E1726 或 E1979 以及使用实验室分析技术（如试验方法）测定铅 E3193 或 E3203 .

1.1 This practice covers the collection of bare soil samples from areas around buildings and related structures using coring and scooping methods. 1.2 This practice may not be suitable for collection of soil samples from areas that are paved or otherwise covered with grass, mulch, or the like. See Guide E2115 or Practices E2271/E2271M or E3074/E3074M . 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. 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. 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 soil samples from bare areas in and around buildings, this practice may also be used to collect soil samples from other areas and environments. 5.2 This practice limits soil collection to approximately the top 1.5 cm (0.6 in.) of soil surface. 5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1726 or E1979 and determination of lead using laboratory analysis techniques such as Test Methods E3193 or E3203 .
