    Revision of D720 - 91(2010) Standard Test Method for Free-Swelling Index of Coal

    (What is a Work Item?)

    Active Standard: D720 - 91(2010)

    Developed by Subcommittee: D05.15 | Committee D05 | Contact Staff Manager



    WK46983

    1. Rationale

    An old D720 ILS from 1986 was found in D05 records. Results from this ILS may not have been formally documented in 1986 because the manner in which test results are generated by D 720 is contrary to the construct of E-691 which was in common use in 1986. A more recent version of E-691 was employed to generate the results in the precision summary. The results for this ILS tend to confirm the current precision values that exist in D 720.
