1、Designation:F316016Standard Guide forMetallurgical Characterization of Absorbable MetallicMaterials for Medical Implants1This standard is issued under the fixed designation F3160;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the ye
2、ar of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guidance document provides metallurgical charac-terization information that may be beneficial in the evaluationo
3、f absorbable metallic materials intended for medical implantapplications.This guide is primarily intended for absorbablemetallic materials that undergo further processing into afabricated final device.Therefore,this standard does notrequire assessments that are more appropriately conducted onthe fin
4、al device,such as biological evaluation.However,a fewrelevant standards for finished implant devices are included forinformation purposes.1.2 The purpose of this guide is to identify appropriate testmethods and relevant medical product standards that can beused to develop future standards for new or
5、 modified absorb-able metallic materials.1.3 This guide is not intended to cover other major classesof absorbable materials such as polymers,ceramics,composites,and tissue-engineered materials.1.4 This standard guide is focused on the chemical,physical,microstructural,and mechanical properties plus
6、in-spection guidelines for metallic materials that are used formedical implants designed to be absorbed in the body over aperiod of time.This guide focuses on material characteriza-tions and does not address device specific mechanical testingthat may be necessary to determine safety and functionalit
7、y ofthe implant.1.5 Compliance with materials specifications developed inaccordance with this standard may not necessarily result in amaterial suitable for its intended purpose.Additional testingspecific to the intended use may be required.1.6 Since surface modifications of medical implants aregener
8、ally applied in the latter stages of manufacturing,thisstandard guide does not cover the characterization of eitherabsorbable or non-absorbable surface coatings that are metallicin origin such as oxides or from the addition of other materialssuch as ceramics or polymers.However,this standard doesapp
9、ly to absorbable metallic materials,regardless of thepresence or absence of a coating.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and
