What is ISO 5834-4 - Oxidation index measurement method about?
ISO 5834 is an international standard that discusses ultra-high-molecular-weight polyethylene for surgical implants. ISO 5834-4 provides the best industry guidance on oxidation index measurement methods to enhance surgical implants.
ISO 5834-4 is the fourth part of a multi-part series that specifies a method for the measurement of the relative extent of oxidation present in ultra-high molecular weight polyethylene (UHMWPE). The material is analysed by infrared spectroscopy.
ISO 5834-4 applies to ultra-high molecular weight polyethylene (UHMWPE) intended for use in surgical implants.
Note 1: Although the method under ISO 5834-4 might give the investigator a means to compare the relative extent of carbonyl oxidation present in various UHMWPE samples, it is recognized that other forms of chemically bound can be important contributors to the characteristics of these materials.
Note 2: Other form...
