ASTM D5192-99

Standard Practice for Collection of Coal Samples from Core

SCOPE
1.1 This practice describes procedures for collecting and handling a coal sample from a core recovered from a borehole.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
