ASTM F1609-08(2014)

1.1This specification covers the material requirements for calcium phosphate coatings for surgical implant applications.

1.2In particulate and monolithic form, the calcium phosphate materials system has been well-characterized regarding biological response (1,2)² and laboratory characterization (2-4). Several publications (5-10) have documented the in vitro and in vivo properties of selected calcium phosphate coating systems.

1.3This specification includes hydroxylapatite coatings, tricalcium phosphate coatings, or combinations thereof, with or without intentional minor additions of other ceramic or metallic,³ and applied by methods including, but not limited to, the following: (1) mechanical capture, (2) plasma spray deposition, (3) dipping/sintering, (4) electrophoretic deposition, (5) porcelainizing, and (6) sputtering.

1.4Substrates may include smooth, porous, textured, and other implantable topographical forms.

1.5This specification excludes organic coatings that may contain calcium and phosphate ionic species.

1.6Warning-Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA's website for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.
