NEN-ISO 6474-2 specifies the characteristics of, and corresponding test methods for bio-stable ceramicbone- substitute material based on a zirconia-reinforced, high-purity alumina matrix composite for use as bone spacers, bone replacements and components in orthopaedic joint prostheses. This document is intended for composite materials which are based on an alumina matrix, i.e. alumina as the dominating phase in the composite with a mass fraction of >60 %, similar to the material described in ISO 6474-1, but extended by means of a certain amount of zirconia and other defined ingredients.
