ASTM WK32373

    Work Item: ASTM WK32373 - Revision of A1038 - 10a Standard Test Method for Portable Hardness Testing by the Ultrasonic Contact Impedance Method

    (What is a Work Item?)

    Active Standard: A1038 - 13

    Developed by Subcommittee: A01.06 | Committee A01 | Contact Staff Manager

    1. Rationale

    At the time of original Inter Laboratory Study there was no accepted reference material data available for determining bias for this test method. Subsequently, the original test materials have been recovered and tested, thereby obtaining adequate data for bias determination. This ballot item adds bias data to the published precision and bias statement.
