1.1 本指南提供了制定和规划废物采样的许多方面的信息（请参阅 1.2 )这在大多数废物采样情况下是常见的。 1.2 本指南涉及的采样方面如下: 部分 安全计划 4. 抽样计划 5. 质量保证注意事项 6. 一般抽样注意事项 7. 保存和集装箱化 8. 清洁设备 9 包装、标签和装运程序 10 监管链程序 11 1.3 本指南不提供这些方面的全面采样程序，也不作为任何特定应用的指南。用户有责任确保使用的程序是适当和充分的。 1.4 单位- 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.5 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。 有关更具体的预防说明，请参阅 3.2 , 3.3 ，和截面 4. . 1.6 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====== 3.1 本指南中涵盖的程序是一般性的，为用户提供了有助于编写采样计划、安全计划、标签和装运程序的信息- 监管程序、一般采样程序、一般清洁程序和一般保存程序。 3.2 就本指南而言，假设用户了解所采样的废物和可能的安全隐患。 3.3 本指南不适用于未知安全隐患的采样现场或废物。在这种情况下，用户应使用其他更合适的程序。

1.1 This guide provides information for formulating and planning the many aspects of waste sampling (see 1.2 ) that are common to most waste sampling situations. 1.2 The aspects of sampling that this guide addresses are as follows: Section Safety plans 4 Sampling plans 5 Quality assurance considerations 6 General sampling considerations 7 Preservation and containerization 8 Cleaning equipment 9 Packaging, labeling, and shipping procedures 10 Chain-of-custody procedure 11 1.3 This guide does not provide comprehensive sampling procedures for these aspects, nor does it serve as a guide to any specific application. It is the responsibility of the user to ensure that the procedures used are proper and adequate. 1.4 Units— The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 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. For more specific precautionary statements see 3.2 , 3.3 , and Section 4 . 1.6 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 ====== 3.1 The procedures covered in this guide are general and provide the user with information helpful for writing sampling plans, safety plans, labeling and shipping procedures, chain-of-custody procedures, general sampling procedures, general cleaning procedures, and general preservation procedures. 3.2 For purposes of this guide, it is assumed that the user has knowledge of the waste being sampled and the possible safety hazards. 3.3 This guide is not to be used when sampling sites or wastes when safety hazards are unknown. In such cases, the user shall use other more appropriate procedures.
