    Work Item: ASTM WK43260 - Revision of E517 - 00(2010) Standard Test Method for Plastic Strain Ratio r for Sheet Metal

    (What is a Work Item?)

    Active Standard: E517 - 00(2010)

    Developed by Subcommittee: E28.02 | Committee E28 | Contact Staff Manager



    1. Rationale

    A note (or other information) needs to be added to E517 that the r-value of magnesium alloys and high strength aluminum alloys are sensitive to the gage length used for its determination. This Work Item will add a statement or brief discussion to this effect to E517. Some discussion as to what to do about this may also be presented.
