Mechanical Requirements8.1 The material supplied under this specification shall conform to the mechanical property requirements in Table 1 and Table2.8.2 Specimens for tension tests shall be prepared and tested in accordance with Test Methods E8/E8M. Tensile properties

45、 shallbe determined using a strain rate of 0.003 to 0.007 in./in./min (mm/mm/min) through yield and then the crosshead speed may beincreased so as to produce fracture in approximately one additional minute.8.2.1 Bar, Forging Bar, Shapes, and WireTest according to Test Methods E8/E8M. Should any test

46、 specimen not meet thespecified requirements, test two additional test pieces representative of the same lot, in the same manner, for each failed testspecimen. The lot will be considered in compliance only if all additional test pieces meet the specified requirements.8.2.2 Tensile tests results for

47、which any specimen fractures outside the gage length shall be considered acceptable, if both theelongation and reduction of area meet the minimum requirements specified. Refer to subsections 7.11.4 and 7.12.5 of Test MethodsE8/E8M. If either the elongation or reduction of area is less than the minim

48、um requirement, discard the test and retest. Retest onespecimen for each specimen that did not meet the minimum requirements.8.3 For sheet and strip, the bend test specimen shall withstand being bent cold through an angle of 105 without fracture in theoutside surface of the bent portion. The bend sh

49、all be made around a mandrel which has a diameter equal to that shown in Table2. Test conditions shall conform to Test Method E290.8.3.1 Sheet, Strip, and PlateTest according to Test Methods E8/E8M. Perform at least one tensile test from each lot in boththe longitudinal and transverse directions. Tests in the transverse direction need be made only on product from which a specimennot less than 8.0 in. (200 mm) in length for sheet and 2.50 in. (64 mm) in length for plate can be taken. Should any of these testspecimens not meet the specified requir
