17、uirements prescribed in5.1.5.5 FinishThe wire shall be free of all imperfections notconsistent with the best commercial practice.6. Test Methods6.1 Tensile Strength and Elongation:6.1.1 Obtain the tensile strength, expressed in pounds persquare inch, by dividing the maximum load carried by thespecim

18、en during the tension test, by the original cross-sectionalarea of the specimen. Tensile strength and elongation may bedetermined simultaneously on the same specimen.6.1.2 Determine the elongation of the wire as the permanentincrease in length due to the breaking of the wire in tension,measured betw

19、een gage marks placed originally 10 in. (250mm) apart upon the test specimen (see Explanatory Note 5).6.1.3 If any part of the fracture takes place outside the gagemarks or in the jaws of the testing machine, or if an examina-tion of the specimen indicates a flaw, the value obtained maynot be repres

20、entative of the material. In such cases the test maybe discarded and a new test made.6.2 ResistivityDetermine the electrical resistivity of thematerial in accordance with Test Method B193 (see Explana-tory Note 6). The purchaser may accept certification that thewire was drawn from rod stock meeting

21、the InternationalStandard forAnnealed Copper instead of resistivity tests on thefinished wire.6.3 Dimensional MeasurementsDimensional measure-ments shall be made with equipment capable of measuring toa graduation of 0.0001 in. (or 0.001 mm). Take measurementson at least three places on each unit sel

22、ected for this test. Ifaccessible, take one measurement on each end and one near themiddle. The average of the three measurements shall determinecompliance with the requirements.6.4 Surface FinishMake a surface-finish inspection withthe unaided eye (normal spectacles accepted).7. Inspection7.1 Gener
