43、er.F560 1313APPENDIXES(Nonmandatory Information)X1. RATIONALEX1.1 The primary purpose of this specification is to char-acterize the chemical, mechanical, and metallurgical propertiesof wrought unalloyed tantalum to be used in the manufacture ofsurgical implants.X1.2 The minimum mechanical properties

44、 specified ensurea baseline of strength and ductility for the highly stresseddevices for which this alloy is typically used.X1.3 Units of MeasureX1.3.1 ASTM PolicyASTM is promoting the use of ratio-nalized SI (metric) units in their standards. The F04.12Committee has modified this specification to f

45、acilitate thetransition by the medical materials industry to SI between 2012and 2018. In the first phase of this transition, running to 2013,the specifications will be structured to allow the use of either SIor inch-pound units. The choice of primary units in eachspecification will be determined by

46、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 as the primary units. Harmonization withcorresponding ISO documents sho

47、uld be considered whenassigning the SI values.X2. BIOCOMPATIBILITYX2.1 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 response can be expected, if the

48、material is used in appropriate applications.X2.2 The material in this specification has been subjected toanimal implant studies and has been shown to produce a wellcharacterized level of biological response that is equal to orless than that produced by the reference material when testedby the proce

49、dures of Practice F981 or the equivalent. Thismaterial has been used clinically for over a decade.4SUMMARY OF CHANGESCommittee F04 has identified the location of selected changes to this standard since the last issue (F560 08)that may impact the use of this standard.
