1.1 本指南是对异质废物采样策略的实用、非数学讨论。本指南与颗粒物采样理论以及推断统计一致，并可作为采样问题统计处理的介绍。 1.2 本指南不提供全面的采样程序，也不作为任何规范的指南。用户有责任确保使用适当的程序。 1.3 单位- 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。所有观察值和计算值应符合实践中确定的有效数字和舍入准则 D6026 . 以国际单位制以外的单位报告试验结果不应视为不符合本标准。 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 本指南适用于异构废物的采样。 4.2 本指南的重点是废物；然而，本指南中描述的方法也可能适用于非废物群体。 4.3 小节 5 – 10 描述根据项目目标对异质废物进行采样的指南。 附录X1 描述了指南在异构废物中的应用。 强烈建议用户阅读 附件A1 阅读和使用章节之前 5 – 10 本指南的。 4.4 附件A1 包含对异质性、分层以及样本和种群的关系的介绍性讨论。 4.5 本指南适用于管理、设计或实施采样和分析计划以表征异构废物的人员。

1.1 This guide is a practical, nonmathematical discussion for heterogeneous waste sampling strategies. This guide is consistent with the particulate material sampling theory as well as inferential statistics, and may serve as an introduction to the statistical treatment of sampling issues. 1.2 This guide does not provide comprehensive sampling procedures, nor does it serve as a guide to any specification. It is the responsibility of the user to ensure appropriate procedures are used. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 . Reporting of test results in units other than SI shall not be regarded as nonconformance with 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 This guide is suitable for sampling heterogeneous wastes. 4.2 The focus of this guidance is on wastes; however, the approach described in this guide may be applicable to non-waste populations as well. 4.3 Sections 5 – 10 describe a guide for the sampling of heterogeneous waste according to project objectives. Appendix X1 describes an application of the guide to heterogeneous wastes. The user is strongly advised to read Annex A1 prior to reading and employing Sections 5 – 10 of this guide. 4.4 Annex A1 contains an introductory discussion of heterogeneity, stratification, and the relationship of samples and populations. 4.5 This guide is intended for those who manage, design, or implement sampling and analytical plans for the characterization of heterogeneous wastes.
