Implants for surgery — Test method for flexural strength of porous calcium salt bone void filler after preconditioning in deaerated phosphate buffered saline

Scope

This document specifies the test method to be followed for measuring and documenting the three-point and four-point flexural strengths of calcium salt based bone void fillers after preconditioning in deaerated phosphate buffered saline to mimic in vivo circumstances. This standard can be applied for all calcium salt based bone void fillers including non-porous ones after appropriate inter-laboratory tests.
This documen t applies to porous calcium salt based bone void fillers with a total porosity ratio of 50 % to 90 % and an average size of macropores of 1 μm to 500 μm as measured by methods described in ISO 13175-3.
