ASTM WK32848

    New Test Method for Determination of the number Average molecular weight of PET yarns based on a relative viscosity value

    (What is a Work Item?)

    Developed by Subcommittee: D35.02 | Committee D35 | Contact Staff Manager



    WK32848

    1. Scope

    The standard covers the procedure and calculation to obtain the number average molecular weight from an inherent viscosity value which is based on the ASTM D4603 test procedure using solvents at a temperature of 25 degrees C.

    High PET Molecular Weight is an indicator property of good durability


    Keywords
