    (What is a Work Item?)

    Active Standard: A985 / A985M - 19

    Developed by Subcommittee: A01.18 | Committee A01 | Contact Staff Manager



    WK71882


    Keywords

    castings; investment castings; master heat; pressure containing; steel castings; sub-heat;;

    Rationale

    Ballot 1: Add a note to Terminology: A941 controlling cross section thickness (Tc) was added for forgings and shall not apply to castings, which provide complex shapes including internal geometry (rationale is both the challenge in determining a Tc for casting and who shall be responsible for it; also casting standards already use casting ruling section T). Ballot 2: Update mechanical testing: a. For consistency and conciseness, add note 1 from A781 to explain text bar relationship. b. For consistency and conciseness, revise sampling, mechanical testing and charpy testing.
