RATIONALEX1.1 The purpose of this specification

28、 is to specify therequirements for the manufacture of wrought 18 chromium-14nickel-2.5 molybdenum stainless steel in the form of surgicalfixation wire.X1.2 Surgical fixation wire shall be handled with care andadequately packaged to prevent damage and contamination ofthe surface.X1.3 For this product

29、, SI units are regarded as the standardhistoric means of size measurement.X2. BIOCOMPATIBILITYX2.1 The alloy composition covered by this specificationhas been employed successfully in human implant applicationsin contact with soft tissue and bone for over a decade. Due tothe well-characterized level

30、 of biological response exhibited bythis alloy, it has been used as a control material in PracticeF 981.X2.2 No known surgical implant material has ever beenshown to be completely free of adverse reactions in the humanbody. Long-term clinical experience of the use of the materialreferred to in this

31、specification, however, has shown that anacceptable level of biological response can be expected, if thematerial is used in appropriate applications.SUMMARY OF CHANGESCommmittee F04 has identified the location of selected changes to this standard since the last issue(F 1350 01) that may impact the u
