ASTM D6418-03

Standard Practice for Using the Disposable En Core Sampler for Sampling and Storing Soil for Volatile Organic Analysis

SCOPE
1.1 This practice is intended for application to soils that may contain volatile waste constituents.
1.2 This practice provides a procedure for using the disposable En Core sampler to collect and store a soil sample for volatile organic analysis.
1.3 It is recommended that this standard be used in conjunction with Practice D 4547 and Guide D 4687.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—ASTM takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
