    Rationale

    ASTM D4596 09(2015) (Channel Sampling) and ASTM D5192 - 09(2015) (Core 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 for 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 D4596 are shown in the bulleted list below: Harmonize the overall format and content of the Planning for Sampling sections of D4596 and D5192. For example, D4596 provides detailed information regarding the effects of weathered coal while D5192 does not even address weathered coal. Add requirements for sampling coal for the determination of standard rank to D4596 rather than having to referring back to D388. Optimize the language in D4596 (especially weathering discussion) including redundancy.
