    (What is a Work Item?)

    Active Standard: D3682 - 13

    Developed by Subcommittee: D05.29 | Committee D05 | Contact Staff Manager



    1. Rationale

    Standards missing or superseded. D121 was missing from the standard. D5142 has been withdrawn and replaced by D7582. Laboratories that do not analyze for calcium or magnesium will not have to make and add a lanthanum solution to their samples and standards. Ionization effects have not been addressed. Interference effects on iron also have not been discussed. Item(s): 11.1, 14.1, 15.1, note 10 (formerly note 8)
