Revision of D5192-09(2015) Standard Practice for Collection of Coal Samples from Core

Keywords

None Provided

Rationale

ASTM D5192 09(2015) (Core Sampling) and ASTM D4596 09(2015) (Channel Sampling) are the two primary methods for collecting samples for coal resource assessments. Both standards contain a section on Planning for Sampling which provides instructions to facilitate planning through the execution of sample collection. In reviewing these two planning sections side-by-side, it was apparent that that revisions are needed. Modifications to these two standards will require separate ballot items. Proposed revisions specifically related to D5192 are shown in the bulleted list below: Harmonize the overall format and content of the Planning for Sampling sections of D4596 & D5192. For example, D4596 provides detailed information regarding the effects of weathered coal while D5192 does not even address weathered coal. Add a discussion on issues regarding weathered coal in D5192. Add the requirements of 100% core recovery and avoidance of weathered coal for Standard Rank determinations in D5192. Add additional emphasis highlighting the importance of ASTM Manual 11 to D5192.
