1.1 本规程涵盖了在桶或类似容器中收集未固结固体样品的典型设备和方法。这些方法专门适用于体积为110美国加仑（416升）或以下的取样桶。这些方法适用于危险材料、产品或废物。具体样品采集和处理要求应在现场具体工作计划中说明。 1.2 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。 1.3 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。 1.4 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 本规程旨在从圆桶或类似容器中收集未固结固体材料的样品，包括不稳定、破裂或以其他方式受损的样品。 EPA/600/2-86/013《危险废物现场的桶处理实践》中描述了特殊处理程序（例如，远程桶打开、超压桶打开、桶脱头等）。

1.1 This practice covers typical equipment and methods for collecting samples of unconsolidated solids in drums or similar containers. These methods are adapted specifically for sampling drums having a volume of 110 U.S. gal (416 L) or less. These methods are applicable to hazardous material, product, or waste. Specific sample collection and handling requirements should be described in the site-specific work plan. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 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. 1.4 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 collecting samples of unconsolidated solid materials from drums or similar containers, including those that are unstable, ruptured, or compromised otherwise. Special handling procedures (for example, remote drum opening, overpressurized drum opening, drum deheading, etc.) are described in EPA/600/2-86/013, Drum Handling Practices at Hazardous Waste Sites.
