BS ISO 5834-3:2019规定了一种试验方法，用于研究超高分子量聚乙烯（UHMWPE）材料在加工和灭菌方法下的氧化稳定性。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。交叉引用:ISO 11542-1ASTM F2003:2015 ISO 11542-2ISO 5834- 2ISO 14243（所有部分）ISO 14242（所有部分）购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 5834-3:2019 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.Cross References:ISO 11542-1ASTM F2003:2015ISO 11542-2ISO 5834-2ISO 14243 (all parts)ISO 14242 (all parts)All current amendments available at time of purchase are included with the purchase of this document.
