本文件规定了研究超高分子量聚乙烯（UHMWPE）材料氧化稳定性的试验方法，作为加工和灭菌方法的一种功能。本文件描述了用于全关节假体的UHMWPE试样和部件加速老化的实验室方法。UHMWPE在高温和高压氧下老化，以加速材料的氧化，从而评估其潜在的长期化学和机械稳定性。

This document specifies a test method for investigating the oxidative stability of ultra-high-molecular-weight polyethylene (UHMWPE) materials as a function of processing and sterilization method. This document describes a laboratory method for accelerated ageing of UHMWPE specimens and components for total joint prostheses. The UHMWPE is aged at elevated temperature and at elevated oxygen pressure, to accelerate oxidation of the material and thereby allow for the evaluation of its potential long-term chemical and mechanical stability.
