This document specifies methods of test for the chemical analysis, assessment of crystallinity ratio and phase composition of hydroxyapatite-based materials such as powders, coating or bulk products.<\/p>\n

\n

NOTE<\/b> These tests are intended to describe properties of the material and to communicate these between organizations. These tests are not written with the objective of replacing a company\u2019s internal operational and assessment tests although they could be used as such.<\/p>\n<\/blockquote>\n
