    (What is a Work Item?)

    Active Standard: D6878 / D6878M - 17

    Developed by Subcommittee: D08.18 | Committee D08 | Contact Staff Manager



    WK57797

    1. Rationale

    A recent large and comprehensive study of TPO revealed that different levels of heat aging performance exist in the market place. A number of industry users of these membranes have asked for the creation of three Types to reflect the actual performance achieved. This proposal only changes the Standard Specification to create three Types with respect to heat aging performance. No other changes are being made. For clarity, the entire standard is shown.
