Description / Abstract:
This test method covers procedures for determining the bulk
density of coal using instrumentation that measures the relative
backscatter of nuclear gamma radiation throughout the depth of the
stockpile under test.
This procedure is applicable to all ranks of coal.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
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. The equipment uses radioactive materials,
which may be hazardous to the health of users, unless proper
precautions are taken.
