ASTM WK40053

    Work Item: ASTM WK40053 - Revision of E1820 - 11 Standard Test Method for Measurement of Fracture Toughness

    (What is a Work Item?)

    Active Standard: E1820 - 13

    Developed by Subcommittee: E08.07 | Committee E08 | Contact Staff Manager



    1. Rationale

    A number of changes to Section A2.4.4 of E1820-11, mainly dealing with the compliance rotation correction for C(T) specimens, are proposed. The rationale for all the changes is enhanced clarity for the user, and the modifications have been discussed and approved by the E08.07.07 subcommittee during the meeting in Atlanta (November 2012).
