ISO 5834-4 Implants for Surgery - Ultra High Molecular Weight Polyethylene - Oxidation Index Measurement Method

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 5834-4 testing. This standard specifies a method for measuring the relative extent of oxidation found in ultra-high molecular weight polyethylene (UHMWPE).

It can be applied to ultra-high molecular weight polyethylene (UHMWPE) intended for use in surgical implants.

The oxidation index is a measure of the degree of oxidation that occurs in the UHMWPE material. Oxidation can occur due to exposure to air, radiation or other environmental factors and can cause a decrease in the mechanical properties of the material over time.

The purpose of ISO 5834-4 is to provide a standardized method for measuring the oxidation index of UHMWPE materials used in surgical implants.

The standard covers the following aspects of the measurement method:

• Sample preparation: The standard specifies the size and shape of the test samples that should be used for the oxidation index measurement, as well as the preparation of the samples.
• Test conditions: The standard provides guidelines for the temperature, time, and atmosphere at which oxidation index measurement should be performed.
• Measurement method: The standard specifies the method for measuring the oxidation index of UHMWPE material using Fourier transform infrared (FTIR) spectroscopy.
• Data analysis: The standard provides guidelines for analyzing data from oxidation index measurement and calculating the oxidation index of UHMWPE material.

In general, ISO 5834-4 provides a standardized method for measuring the oxidation index of UHMWPE materials used in surgical implants. By measuring the oxidation index, manufacturers can assess the degree of oxidation in the material and take appropriate measures to prevent further oxidation, which is important for ensuring the long-term stability and durability of surgical implants.
