ASTM WK68581

    Revision of C567 / C567M - 14 Standard Test Method for Determining Density of Structural Lightweight Concrete

    (What is a Work Item?)

    Active Standard: C567 / C567M - 19

    Developed by Subcommittee: C09.21 | Committee C09 | Contact Staff Manager



    WK68581


    Keywords

    equilibrium density; lightweight concrete; oven-dry density;

    Rationale

    The ballot is to add tolerances to selected times listed in the test method. This ballot is the result of comments submitted to the subcommittee by users of the test method. In the current version there is no tolerance for certain action times. Even though the use of significant digits could be used by the user of the standard to establish these tolerances, the subcommittee feels that inclusion of established tolerances from other ASTM C9 standards which cover similar activities would be beneficial to the users of the standard. The tolerances included in this ballot item are generally based upon those in section 7.3 of standard C39.
