2、ision.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 The objective of this guide is to advise researchers onthe possible high demand wear test features that should beincluded in evalua
3、tion of hard on hard articulations.This guidemakes suggestions of what high demand test features may needto be added to an overall high demand wear test regime.Devicearticulating components manufactured from other metallicalloys,ceramics or with coated or elementally modified sur-faces could possibl

5、h surface hardness.An argument has been made that thehard-on-hard THR articulation may be better for younger moreactive patients.These younger patients may be more physicallyfit and expect to be able to perform more energetic activities.Consequently,new designs of hard-on-hard THR articulationsmay h
6、ave some implantations subjected to more demandingand longer wear performance requirements.1.3 Total Hip Replacement(THR)with metal-on-metalarticulations have been used clinically for more than 50 years(1,2).2Early designs had mixed clinical results.Eventuallythey were eclipsed by THR systems using
7、metal on polyeth-ylene articulations.In the 1990s the metal-on-metal articula-tion again became popular with more modern designs(3),including surface replacement.1.4 In the 1970s the first ceramic-on-ceramic THR articu-lations were used.In general,the early results were notsatisfactory(4,5).Improvem
8、ent in alumina,and new designsin the 1990s improved the results for ceramic-on-ceramicarticulations(6).1.5 The values stated in SI units are to be regarded as thestandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of
9、 the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3F75 Specification for Cobalt-28 Chromium-6 MolybdenumAlloy Castings and Casting Alloy for Surgical Implan
