1.1 本规程涵盖了使用勺子收集土壤和物理相似材料的表面和近表面样品的方法和设备。 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。 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 本规程旨在收集受污染土壤和类似材料的样本。 5.2 勺主要用于收集表面附近的样本。可以通过首先使用铁铲或其他合适的设备移除更高层，然后用勺子收集样本来获得地下样本。 5.3 由于其简单性，在其他类型的采样设备存在去污或处理问题的情况下，勺在采集废物样本时非常有用。 勺也适用于快速筛选项目、试点研究和其他半定量调查。 5.4 应根据适当的工作计划收集样本（见实践 D5283 和指南 D4687 ).

1.1 This practice covers the method and equipment used to collect surface and near-surface samples of soils and physically similar materials using a scoop. 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. 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 collecting samples of contaminated soils and similar materials. 5.2 Scoops are used primarily for collecting samples near the surface. Subsurface samples can be obtained by first removing higher layers using a shovel or other suitable equipment and collecting the sample with the scoop. 5.3 Because of their simplicity, scoops are useful in taking samples of waste materials where decontamination or disposal is a problem with other types of sampling equipment. Scoops are also suitable for use in rapid screening programs, pilot studies, and other semi-quantitative investigations. 5.4 Samples should be collected in accordance with an appropriate work plan (see Practice D5283 and Guide D4687 ).
