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.

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.
