1、Designation:F202708Standard Guide forCharacterization and Testing of Raw or StartingBiomaterials for Tissue-Engineered Medical Products1This standard is issued under the fixed designation F2027;the number immediately following the designation indicates the year oforiginal adoption or,in the case of
2、revision,the year 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 document provides guidance on writing a materialsspecification for raw or starting biomaterials i
3、ntended for use intissue engineering scaffolds for growth,support,or delivery ofcells and/or biomolecules.This guide does not apply tobiomaterials that are already in a scaffold form or are finishedtissue-engineered medical products.1.2 The purpose of this guide is to provide a compendium ofrelevant
4、 existing standards and test methods for biomaterialsalready commonly used within medical products and to pro-vide characterization guidance for interim use of raw bioma-terials for which a standard does not exist.1.3 This guide covers specifications and characterizations ofall the major classes of
5、materials including polymers,ceramics,metals,composites,and natural tissues of human,animal,orplant origin.This guide does not apply to pharmaceuticals.1.4 This guide is focused on specification of chemical,physical,and mechanical properties of the raw or startingmaterial.It does not include safety
6、and biocompatibilityrequirements since safety and biocompatibility testing is typi-cally done on materials fabricated into a final form to includeall possible effects of fabrication and sterilization techniques.1.5 Compliance with materials specifications developed inaccordance with this standard ma
