Significance and Use | ||||||||
The measured mean bulk density of a coal stockpile is used with a measurement of the stockpile volume per Test Method D6172. Procedures to determine the quantity of stockpiled coal. This measure of quantity is often used as a reference value for adjusting inventory records. |

1. Scope | ||||||||
1.1 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. 1.2 This procedure is applicable to all ranks of coal. 1.3 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. 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. The equipment uses radioactive materials, which may be hazardous to the health of users, unless proper precautions are taken. |
