【国外标准】 Standard Practice for Sampling with a Scoop

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).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.
