ASTM WK37810

    Work Item: ASTM WK37810 - Revision of E18 - 11 Standard Test Methods for Rockwell Hardness of Metallic Materials

    (What is a Work Item?)

    Active Standard: E18 - 14

    Developed by Subcommittee: E28.06 | Committee E28 | Contact Staff Manager

    1. Rationale

    Currently there are no requirements defining how to verify indenters that, because of their shape, cannot perform tests using the Rockwell scales normally called out for verification. This,for example,applies to side cut diamonds that cant, because of their shape, support HRC scale forces and thin tip ball indenters that cant support HRB scale test forces. This revision will define how to verify those indenters.
