scope:

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

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).

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.

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

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

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
