ASTM WK43431

    Revision of C117 - 13 Standard Test Method for Materials Finer than 75-μm (No. 200) Sieve in Mineral Aggregates by Washing

    (What is a Work Item?)

    Active Standard: C117 - 13

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



    WK43431

    1. Rationale

    Currently, many concrete and concrete materials testing laboratories use scales, ovens, and other apparatus that are calibrated and read in SI (metric)or Non-SI (US customary) units that read mass in pounds and temperature in degrees fahrenheit. Therefore, revisions are being made to convert ASTM C117 to a combined SI and Non-SI standard.
