ASTM WK46283

    Revision of E8 / E8M - 13a 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



    WK46283

    1. Rationale

    Discussion with committee A01.13 led to the understanding that in Section 7.7 could provide more guidance to the user for dealing with stress-strain curves whose shapes are less than ideal. This revision clarifies the language of 7.7 and adds an appendix (non-mandatory) with some example non-ideal stress-strain curves and guidance on how to draw the line for computing the offset yield strength.
