This specification covers ultra-high-molecular-weight polyethylene (UHMWPE) powder and fabricated forms for use in surgical implants. UHMWPE powder shall be of virgin polymer manufactured from a homopolymer of ethylene, while the fabricated forms shall be manufactured from the same UHMWPE powder without any stabilizers or processing aids. Tests for viscosity number, elongation stress, ash content, extraneous matter, and trace elements shall be performed for UHMWPE powders, while tests for density, ash content, tensile strength, yield strength, elongation, and impact strength shall be performed for fabricated forms. All tests shall conform to the requirements specified.
