ASTM WK44173

    Work Item: ASTM WK44173 - Revision of D7708 - 11 Standard Test Method for Microscopical Determination of the Reflectance of Vitrinite Dispersed in Sedimentary Rocks

    (What is a Work Item?)

    Active Standard: D7708 - 11

    Developed by Subcommittee: D05.28 | Committee D05 | Contact Staff Manager

    1. Rationale

    Users of this standard frequently report non-compliant results with 20 measurements due to natural variability in the material being tested. The revision is to insert a statement in the reporting section that non-compliant analyses with 20 measurements can be used as a qualitative measure as long as the report states that it is a noncompliant analysis.
