ASTM WK37994

    Revision of C1293 - 08b Standard Test Method for Determination of Length Change of Concrete Due to Alkali-Silica Reaction

    (What is a Work Item?)

    Active Standard: C1293 - 08b

    Developed by Subcommittee: C09.26 | Committee C09 | Contact Staff Manager


    1. Rationale

    In the precision and bias section of the method, data are given as within-laboratory values, when in actuality the do not meet the ASTM definition of within- laboratory test result statistics. Rather they are statistics concerning test determinations, not test results. This work item is to correct the terminology in this section, while preserving the information that is still useful to users of the method.
