    WK71879


    Keywords

    castings; general requirements; pressure containing; steel;;

    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: Remove references to investment casting (7.1 last sentence and 7.4) - these are now covered by A985. And, remove other castings form 7.5. Ballot 3: Update mechanical testing: a. For consistency and conciseness, add note 1 from A781 to explain text bar relationship. b. For consistency and conciseness, revise mechanical testing and charpy testing.
