ASTM WK29420

    Revision of E8 / E8M - 09 Standard Test Methods for Tension Testing of Metallic Materials

    (What is a Work Item?)

    Active Standard: E8 / E8M - 13a

    Developed by Subcommittee: E28.04 | Committee E28 | Contact Staff Manager



    WK29420

    1. Rationale

    Current language allows % elongation at fracture to be reported instead of % elongation in some cases. People looking at test results are not catching the difference and are accepting material that does not pass % elongation requirements. The language needs to be made clearer that these two are not the same value and should not be reported as such.
