Dimensions and Permissible Variation8.1 Units of Measure:8.1.1 SelectionThis specification requires that the pur-chaser select the units of measure (SI or inch-pound) to be usedfor product certification. In the absence

26、 of a stated selection ofunits on the purchase order, this selection may be expressed bythe purchaser in several alternate forms listed in order ofprecedence.8.1.1.1 If the purchaser and supplier have a history of usingspecific units, these units shall continue to be certified untilexpressly changed

27、 by the purchaser.8.1.1.2 In the absence of historic precedence, if the unitsused to define the product on the purchasers PO, specification,and engineering drawing are consistent, these units shall beused by the supplier for product certification.8.1.1.3 If the purchasers selection of units is uncle

28、ar, theunits of measure shall be agreed upon between purchaser andsupplier.8.1.2 Conversion of UnitsIf the suppliers test equipmentdoes not report in the selected units, the test equipment unitsmay be converted to the selected units for certification pur-poses. Accurate arithmetic conversion and pro

29、per use ofsignificant digits should be observed when performing thisconversion. ASTM SI 10 provides guidelines for the use of SIunits. Annex A provides conversion tables and Annex Bprovides rules for conversion and significant digits.9. Special Tests9.1 If supplied in the annealed condition, the ave

RATIONALEX1.1 The primary reason for this specification is to char-acterize the composition and properties to assure consistency inthe starting material used in the manufacture of medicaldevices.X1.2 The

37、acceptable metal conditions include annealed,cold-worked, or cold-worked and capability-aged. The choiceis dependent upon the medical device design and its intendedapplication.X1.3 Units of Measure:X1.3.1 ASTM PolicyASTM is promoting the use ofrationalized SI (metric) units in their standards. The F

38、04.12subcommittee has modified this specification to facilitate thetransition by the medical materials industry to SI units betweennow and 2018. In the first phase of this transition, running to2013, the specifications will be structured to allow the use ofeither SI or inch-pound units. The choice o

39、f primary units ineach specification will be determined by the industry using thespecification. The change to SI units during this period may beinitiated by the purchaser through his purchase documentation.In the second phase of this transition, the specifications will bewritten with SI units as the

40、 primary units. Harmonization withcorresponding ISO documents should be considered whenassigning the SI values.X2. BIOCOMPATIBILITYX2.1 The alloy composition covered by this specificationhas been successfully employed in human implants (1-5)4forover a decade. Due to the well-characterized level of b

41、iologicalresponse exhibited by this alloy, it has been used as a controlmaterial in Practice F981.X2.2 No known surgical implant material has ever beenshown to be completely free of adverse reactions in the humanbody. However, long term clinical experience has shown anacceptable level of biological

42、response can be expected, if thematerial is used in appropriate applications4The boldface numbers in parentheses refer to the list of references at the end ofthis specification.F688 103REFERENCES(1) Gaechter, A., and Galante, G., “MP35N, A Corrosion ResistantHigh-Strength Alloy for Orthopaedic or Su
