    Revision of D4417 - 19 Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel

    (What is a Work Item?)

    Active Standard: D4417 - 21

    Developed by Subcommittee: D01.46 | Committee D01 | Contact Staff Manager



    WK73393


    Keywords

    abrasive; abrasive blast cleaning; anchor pattern; peak count; peak density; peak height; surface profile; surface roughness;;

    Rationale

    At the recent D01.46 committee meeting, concerns arose surrounding touching of the blasted substrate while preforming the test method. Currently, Method A allows for comparison to be done with the unaided eye, under 5 to 10 power magnification, or by touch. It was agreed that all present that the reference to or by touch should be removed, and that the comparator should be used only visually or with magnification.
