ASTM WK46038

    Revision of A763 - 93(2009) Standard Practices for Detecting Susceptibility to Intergranular Attack in Ferritic Stainless Steels

    (What is a Work Item?)

    Active Standard: A763 - 14

    Developed by Subcommittee: A01.14 | Committee A01 | Contact Staff Manager



    WK46038

    1. Rationale

    The copper sulfate - 16% sulfuric acid test procedure does not specify use of reagent grade copper sulfate. Specifying use of reagent grade copper sulfate will make this procedure consistent with other A763 procedures and should eliminate a potential source of variation.
