ASTM WK42069

    Work Item: ASTM WK42069 - Revision of G3 - 89(2010) Standard Practice for Conventions Applicable to Electrochemical Measurements in Corrosion Testing

    (What is a Work Item?)

    Active Standard: G3 - 13

    Developed by Subcommittee: G01.11 | Committee G01 | Contact Staff Manager

    1. Rationale

    Fig.2 is an illustration on how polarization resistance curve would look like. The curve shape currently presented is not typically observed during actual measurement. Therefore, it is replaced with the one of shape frequently observed during measurement.
