Anotácia

This guide covers extensively irradiation-crosslinked ultra-high molecular weight polyethylene (UHMWPE) fabricated forms for surgical implant applications. Only gamma and electron beam irradiated extensively crosslinked materials are covered by this guide. Chemical composition and physical properties of extensively crosslinked UHMWPE fabricated form shall conform to the requirements of this guide which include ultimate tensile strength, yield strength, elongation, Izod impact strength, ultimate load, fatigue crack propagation, compressive modulus, percent crystallinity, melting temperature, residual free radicals, swell ratio, oxidation index, and t-vinylene content. Biocompatibility of the material shall also be considered when new applications of the material, or modification to the material or physical forms of the materials are being contemplated.
