Scope

1.1 This practice covers procedures for obtaining soils from core barrel samplers for chemical and physical analysis, with an emphasis on the collection and handling procedures that maintain the representativeness of the chemical contaminants of concern. Core barrel samplers are initially empty (hollow) until they are pushed into the ground to collect and retrieve a cylindrical soil sample with minimal disturbance. The selection of equipment and the sample handling procedures are dependent on the soil properties, the depth of sampling, and the general properties of the chemical contaminants of concern, that is, volatile organic compounds, semi-volatile organic compounds, and inorganic constituents. The sampling procedures described are designed to maintain representative concentrations of the contaminants regardless of their physical state(s), that is, solid, liquid, or gas. 1.2 This practice covers soil samplers used in Guide D6169 on soils and rock sampling and included in Guide D6232 for waste sampling. Guide D6169 provides additional information on samplers and procedures that will preserve representative contaminate concentrations. Guide D6282 is on direct-push soil samplers that are most frequently used for environmental work. Guide D4547 addresses special sampling of soils for volatile compounds. This standard does not include sediment samplers in Guide D4823, but the same principles may apply to handling of those cores. Guide D4700 includes information on shallow manual push soil samplers. 1.3 Five general types of core barrel samplers are discussed in this practice: split-barrel, soil corer, ring-lined barrel, thinwalled tube, and solid-barrel samplers. 1.4 This document does not cover all the core barrel devices that are available for the collection of soil samples. 1.5 The procedures described may or may not be applicable to handling of samples for assessing certain geotechnical properties, for example, soil porosity. NOTE 1—Prior to commencement of any intrusive exploration, the site should be checked for underground utilities. 1.6 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard. 1.7 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. 1.8 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.
