ASTM WK44265

    Revision of C534 / C534M - 13 Standard Specification for Preformed Flexible Elastomeric Cellular Thermal Insulation in Sheet and Tubular Form

    (What is a Work Item?)

    Active Standard: C534 / C534M - 14

    Developed by Subcommittee: C16.22 | Committee C16 | Contact Staff Manager


    1. Rationale

    A suggestion was made at the last subcommittee meeting to change the WVT on Grade 2 and Grade 3 to match the Mil spec requirement. The current WVT value is 0.10 perm and the Mil spec is 0.30 perm. We felt this change would more accurately reflect the current Mil spec requirement as the minimum.
