RATIONALEX1.1 This specification is needed to ensure a high qualitymaterial for use in
18、 medical device applications. The chemical,crystallographic, and phase requirements serve as criteria for ahigh-purity, consistent product that can be implanted in thebody. These requirements provide specifications for biocom-patible grades of beta-tricalcium phosphate for use in thephysiological en

20、PATIBILITYX2.1 This specification is needed to ensure a high qualitymaterial for use in biological applications. beta-tricalciumphosphate has been demonstrated to exhibit a well character-ized biological response equivalent or better than that exhibitedby reference materials cited and tested in Prac
21、tices F981 andF748 or equivalent. The chemical, crystallographic, and phaserequirements contained in this specification serve as criteria fora high purity, consistent product that can be implanted in thebody. The suitability of the material from a human implantperspective is dependent on the specifi
22、c application. Thebiological test appropriate for the specific site, such as recom-mended in Practice F748 or ISO 10993 should be used as aguideline. Further testing of specific properties may be re-quired for specific applications.ASTM International takes no position respecting the validity of any
23、patent rights asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject to revis
24、ion at any time by the responsible technical committee and must be reviewed every five years andif not revised, either reapproved or withdrawn. Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters. Your c
25、omments will receive careful consideration at a meeting of theresponsible technical committee, which you may attend.
