3、valuationof 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 conduc

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 stan

7、fety and functionality 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 med

The lack of a standard guide for themetallurgical characterization of these new materials maycontribute to material property non-uniformity which couldcreate varia

It is the intent of this guide to provide materialproperty information, corresponding test methods, and relevantmedical product standards to serve as a guide for the metal-lurgical characterization of new or modified materials. Theseguidelines ar

The characterization and testing of absorb-able meta

37、llic materials after they have been manufactured intofinished and sterilized medical implants will depend on thedesign, mass, shape, anatomic location, and end-use applica-tion.5. Significance and Use5.1 The metallurgical properties of materials used to manu-facture absorbable metallic implants can

46、.1 and 6.3.2.6.3.5 Elemental concentrations present at specified major,minor, residual, or trace levels are defined in A751 and ISO3116. Within this context, a trace classification does notinclude elements that are a specified component of the alloy,regardless of concentration.NOTE 1For the material

47、s covered by this standard, no biocompatibil-ity assessment is required since this standard focuses on characterizationof materials that are subject to further fabrication into a final device.However, since the overall composition of any absorbable implant can beexpected to have a significant impact

48、 on its biocompatibility, the entirecomposition of materials covered by this standard (including the intendedcomposition, metallic degradation species, and any residual or tracemetallic or non-metallic impurities) should be preliminarily assessed fortheir potential impact on any later ISO 10993 risk

49、 assessment of the finaldevice. In addition to the ISO 10993 series, additional supplementalguidance specific for the biological evaluation of absorbable implants canbe found in ISO TR37137.6.3.6 Chemical analysis may be performed according toE354 for Fe-base materials, B954 for Mg-base materials, andE536 for Zn-base materials.6.3.7 Chemical check analysis tolerance limits specified inAMS 2248 may be used to verify heat analysis of Fe-basematerials.5Hendra Hermawan, Biodegradable Metals from Concept to Applications,Spinger, 2012, ISSN 2192-1091; ISSN 2192- 1
