ASTM WK39767

    Revision of A630 - 03(2009) Standard Test Methods for Determination of Tin Coating Weights for Electrolytic Tin Plate

    (What is a Work Item?)

    Active Standard: A630 - 03(2014)

    Developed by Subcommittee: A01.20 | Committee A01 | Contact Staff Manager



    WK39767

    1. Rationale

    It was noted that the precision statement should cover the range of coating weights listed in A624. ASTM staff indicated that it is acceptable to provide the precision statements for Low, Medium, and Heavy coating weights instead of the full range. The Task Group agreed that the Work Item 2 will cover the Low range. Commercial tinplate samples of 0.50 and 1.00 lb/bb will be secured to start the new round robin testing.
