ASTM WK44263

    Revision of C802 - 09a Standard Practice for Conducting an Interlaboratory Test Program to Determine the Precision of Test Methods for Construction Materials

    (What is a Work Item?)

    Active Standard: C802 - 09a

    Developed by Subcommittee: C09.94 | Committee C09 | Contact Staff Manager


    1. Rationale

    The work item involves a major revision to Practice C802-9a. Terminology will be revised to be consistent with terminology in the companion Practice C670-13. The method for checking data consistency will be changed to the method used in Practice E691. The example used to illustrate ILS data analysis will be revised to be more representative of a typical data set from an ILS. A new Appendix will be added to deal with test methods that involve the use of test results from more than one batch of a cementitious mixture. Another new Appendix will cover the use of ANOVA to analyze ILS data.
