Material

16、 Requirements6.1 The starting material used to make fixation wire must meet the requirements of Specification F138.6.2 Surgical fixation wire shall conform to the specified chemical requirements of Specification F138. Conformance with thisstandard shall be so identified by suitable packaging, labeli

17、ng, or both.7. Mechanical Requirements7.1 Surgical fixation wire shall conform to the appropriate mechanical properties specified in Table 1.7.2 Perform tension tests in accordance with Test Methods E8E8/E8M using a 254 mm (10 in.)10 in. gage length and across-head speed of 254 mm/min (10 in./min).1

18、0 in./min. Should any of the test specimens not meet the specified requirements,test two additional test pieces representative of the same lot, in the same manner, for each failed test piece. The lot shall beconsidered in compliance only if all additional test pieces meet the specified requirements.

19、7.3 Tensile test results for which any specimen fractures outside the gage length shall be considered acceptable if the elongationmeets the minimum requirements specified in Table 1. Refer to subsections 7.11.4 and 7.11.5 of Test Methods E8E8/E8M. If theelongation is less than the minimum requiremen

20、t, discard the test and retest. Retest one specimen for each specimen that did notmeet the minimum requirement.7.4 The wire shall meet the requirements of the latest version of USP for Nonabsorbable Surgical Sutures, when tested inaccordance with 7.2.8. Dimensional Requirements8.1 Surgical fixation

21、wire shall be fabricated in accordance with the dimensions and tolerances specified in Table 1.8.2 Unless otherwise specified, size tolerances are plus and minus as shown in Table 1. When required by the purchaser, roundwire tolerances may be specified all plus and nothing minus, or all minus and no

22、thing plus, or any combination of plus and minusif the total spread in size tolerance is not less than the total spread shown in Table 1.8.3 The maximum out-of-round tolerance for round wire is one-half of the size tolerance given in Table 1.8.4 Units of Measure8.4.1 SelectionThis specification requ

23、ires that the purchaser select the units (SI or inch-pound) to be used for productclarification. In the absence of a stated selection of units on the purchase order, this selection may be expressed by the purchaserin several alternate forms listed in order of precedence.8.4.1.1 If the purchaser and

24、supplier have a history of using specific units, these units shall continue to be certified untilexpressly changed by the purchaser.8.4.1.2 In the absence of historic precedence, if the units used to define the product on the purchasers purchase order (PO) areconsistent with the specification and en

25、gineering drawing, then these units shall be used by the supplier for product certification.8.4.1.3 If the purchasers selection of units is unclear, the units of measure shall be agreed upon between the purchaser andsupplier.8.4.2 Conversion of UnitsIf the suppliers test equipment does not report in

26、 the selected units, the test equipment units maybe converted to the selected units for certification purposes. Accurate arithmetic conversion and proper use of significant digitsshould be observed when performing this conversion. IEEE/ASTM SI 10 provides guidelines for the use of SI units. Annex A

27、ofIEEE/ASTM SI 10 provides conversion tables and Annex B of IEEE/ASTM SI 10 provides rules for conversion and significance.9. Surface Condition Requirements9.1 Surgical fixation wire is usually furnished in the bright-annealed condition. Other surface finishes shall be specified asagreed to between

28、supplier and purchaser.F1350 1529.2 The surface of surgical fixation wire conforming to this specification shall be processed to minimize imperfections such astool marks, nicks, scratches, cracks, cavities, spurs, and other defects that would impair the serviceability of the wire. The surfacesshall

Such passivation process shall beperformed in accordance with Practice F86.10. Significance of Numerical Limits10.1 The following applies to all specified num

30、erical limits in this specification. To determine conformance to these limits, anobserved or calculated value shall be rounded to the nearest unit in the last right hand digit used in expressing the specificationlimit, in accordance with the rounding method of Practice E29.TABLE 1 Mechanical and Dim
