    Rationale

    In the interest of providing specific guidance to users of D2013 (Preparing coal samples for analysis), we are proposing to add an appendix to D2013 which would give users guidance on subdividing run-of-mine samples without crushing. The draft will contain instructions for a long-pile division technique for dividing large mass or large top size samples prior to reducing to 4 mesh and using a riffle.
