    This specification covers chemical and crystallographic requirements for hydroxylapatite intended for surgical implants. Elemental analysis for calcium and phosphorus will be consistent with the expected stoichiometry of hydroxylapatite. The calcium and phosphorus contents shall be determined using a suitable method such as ion chromatography. A quantitative X-ray diffraction analysis shall indicate a minimum hydroxylapatite content of 95 %. The concentration of trace elements such as arsenic, cadmium, mercury, and lead shall be determined for hydroxylapatite derived from natural resources. The analysis of other trace elements may be required, based on the conditions, apparatus, or environments specific to the manufacturing techniques and raw materials. Either inductively coupled plasma/mass spectroscopy (ICP/MS), atomic absorption (AAS), or the methods mentioned shall be used.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers chemical and crystallographic requirements for hydroxylapatite intended for surgical implants. For a material to be called hydroxylapatite, it must conform to this specification. (See Appendix X1.)

    1.2 The biological response to hydroxylapatite in soft tissue and bone has been characterized by a history of clinical use (1-3)2 and by laboratory studies (4-6) .

    1.3 This specification includes powder, particulate, and forms intended for use as surgical implants, components of surgical implants, or as raw materials for manufacturing processes such as thermal spray coating, electrophoretic deposition, physical vapor deposition, and so forth.

    1.4 This specification specifically excludes hydroxylapatite coatings, amorphous calcium phosphate, ceramic-glasses, tribasic calcium phosphate, whitlockite, and alpha- and beta-tricalcium phosphate. (See Specification F1088.)

    1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
