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.
