ASTM WK70031

    New Practice for Preconditioning of Polymer-Based Bearing Materials for Non-Clinical Testing

    (What is a Work Item?)

    Developed by Subcommittee: F04.22 | Committee F04 | Contact Staff Manager



    WK70031

    1. Scope

    This standard practice is to provide various methods for preconditioning polymers used in joint replacement prostheses. Preconditioning methods would focus on aging for non-clinical mechanical testing.


    Keywords

    joint prosthesis materials; joint prostheses; joint replacements; preconditioning; pre-conditioning; accelerated aging; aging; oxidation; stability; UHMWPE; UHMW PE; ultra-high molecular weight polyethylene; crosslinked PE; XLPE; cross-linked polyethylene

    Rationale

    ASTM F2003 is a standard practice for accelerated aging of PE that has been gamma-irradiated in air. This standard was created to differentiate the mechanical properties of different sterilization methods (gamma, EtO, gas plasma, etc); however, there are no guidelines or practices available for next generation polyethylene materials that have undergone different processes, and/or have incorporated Vitamin E.

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