ASTM WK44004

    Revision of F648 - 13 Standard Specification for Ultra-High-Molecular-Weight Polyethylene Powder and Fabricated Form for Surgical Implants

    (What is a Work Item?)

    Active Standard: F648 - 14

    Developed by Subcommittee: F04.11 | Committee F04 | Contact Staff Manager



    WK44004

    1. Rationale

    The task group agreed to eliminate the requirement for measurement of Ash content for the consolidated forms of UHMWPE (in Table 2), because it is already required to be measured on the powder (Table 1). Nothing is added to the powder during molding that could affect the amount of ash. The requirements for extraneous matter and incompete consolitation continue to be relevant and are unaffected by this proposed revision.
