Anotace textu normy ASTM F1088-23 :
This specification covers chemical and crystallographic requirements for biocompatible beta-tricalcium phosphate for surgical implant applications. Elemental analysis for calcium and phosphorus will be consistent with the expected stoichiometry of beta-tricalcium phosphate. The calcium and phosphorus content shall be determined using a suitable method such X-ray fluorescence. A quantitative X-ray diffraction analysis shall indicate a minimum beta-tricalcium phosphate content of 95 % as determined using powder diffraction method. The analysis of other trace elements may be required, based on the conditions, apparatus, or environment. It is recommended that all metals or oxides present in concentrations equal or greater than 0.1 % be noted in material descriptions.
Keywords:
advanced ceramics, ?-TCP, beta-tricalcium phosphate, calcium phosphate material, ceramic, surgical implant,, ICS Number Code 11.040.40 (Implants for surgery, prothetics and orthotics)

1.1?This specification covers chemical and crystallographic requirements for beta-tricalcium phosphate (?-TCP) raw materials intended for use in medical device applications. For a material to be identified as medical-grade beta-tricalcium phosphate, it must conform to this specification (see Appendix X1). 1.2?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. 1.3?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. |
