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


    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


    Viscosity, PET, Molecular Weight

    The title and scope are in draft form and are under development within this ASTM Committee.
