ASTM WK45063

    Revision of C1777 - 13 Standard Test Method for Rapid Determination of the Methylene Blue Value for Fine Aggregate or Mineral Filler Using a Colorimeter

    (What is a Work Item?)

    Active Standard: C1777 - 13

    Developed by Subcommittee: C09.20 | Committee C09 | Contact Staff Manager



    WK45063

    1. Rationale

    This item removes the d2s statement, which addresses the maximum difference expected between two duplicate test results. This statement can be added once an Interlaboratory Study (ILS) is completed. An ILS will provide a better indication of d2s because it will include a pooled estimate of standard deviation based on multiple operators. It will also include different levels of methylene blue value.
