1.1 本规程涵盖了从卡车收集废物样本的几种方法。这些方法专门适用于使用几种类型的采样设备对散装未固结固体废物进行采样。 1.2 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。 参见第节 6. 具体预防说明。 1.3 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====== 5.1 本规程旨在用于废物管理行业，从卡车上收集未固结废物的样本。所述采样程序是通用的，应与现场特定工作计划结合使用。 5.2 直接从卡车（而不是废物源）收集废物样本的目的通常是验证（通常通过筛选分析）卡车中包含的废物是否与先前已鉴定并批准用于处理或处置的废物源中的相同或类似材料，或两者都是。此外，从垃圾源上方的卡车上对垃圾进行采样可能更安全或在物流上更容易。

1.1 This practice covers several methods for collecting waste samples from trucks. These methods are adapted specifically for sampling unconsolidated solid wastes in bulk loads using several types of sampling equipment. 1.2 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. See Section 6 for specific precautionary statements. 1.3 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 practice is intended for use in the waste management industries to collect samples of unconsolidated waste from trucks. The sampling procedures described are general and should be used in conjunction with a site-specific work plan. 5.2 The purpose of collecting waste samples directly from a truck (rather than the waste source) is often to verify (usually with screening analyses) that the waste contained in the truck is the same or similar material from a waste source that has been previously characterized and approved for treatment or disposal, or both. Additionally, it may be a safer or logistically easier to sample the waste from a truck over the waste source.
