ASTM WK44513

    Revision of D7430 - 13 Standard Practice for Mechanical Sampling of Coal

    (What is a Work Item?)

    Active Standard: D7430 - 14

    Developed by Subcommittee: D05.23 | Committee D05 | Contact Staff Manager


    1. Rationale

    It was requested that the Task Group for D 7430 on Mechanical Sampling review its definitions and settle on a term for the sample produced by a mechanical sampling system so that this single term can be used in the flow charts for the preparation standard D 2013 and the moisture standard D 3302. Earlier in 2013, a ballot successfully passed with a new definition. With this ballot there was one vote Affirmative with Comment where the comment was discussed and accepted by the Task Group as a further useful refining of the definition in 3.2.23. Specifically that the System Sample be further clarified to be from the final stage of a mechanical sampling system.
