22、y specimen fracturesoutside the gage length shall be considered acceptable, if boththe elongation and reduction of area meet the minimumrequirements specified. Refer to Test Method E8, sections7.11.4 and 7.11.5.7.3.3 If either the elongation or the reduction of area is lessthan the minimum requireme
23、nt, discard the test and retest.Retest one specimen for each specimen that did not meet theminimum requirements.7.3.4 Sheet, Strip, and PlatePerform at least one tensiontest for each lot. Tension property requirements apply in boththe longitudinal and transverse directions. Tests in the trans-verse
24、direction need be made only on product from which aspecimen is not less than 8.0 in. (200 mm) in length for sheetand 2.50 in. (64 mm) in length for plate can be taken. Shouldany of these test pieces not meet the specified requirements,test two additional test pieces representative of the same lot, i
25、nthe same manner, for each failed test piece. The lot shall beconsidered in compliance only if both additional test piecesmeet the specified requirements.8. Certification8.1 The supplier shall provide a certification that the mate-rial was tested in accordance with this specification and met allrequ
26、irements. A report of the test results shall be furnished tothe purchaser at the time of shipment.9.

However, long term clinical experience has shown anacceptable level of biological response can be expected, if thematerial is used i
40、n appropriate applications.X2.2 The material in this specification has been subjectedto animal 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 procedures of Practice
41、F 981 or the equivalent. Thismaterial has been used clinically for over a decade.5SUMMARY OF CHANGESCommittee F04 has identified the location of selected changes to this standard since the last issue (F 560 07)that may impact the use of this standard.
