28、 shall be made on representative samples.The elongation of the wire shall be determined by measuringthe permanent increase in length, due to the breaking of thewire in tension, between gauge marks placed originally 10 in.(250 mm) apart upon the test specimen (see Explanatory Note5).7.5 If any part o
29、f 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 representative of the material.

36、e best commercial practice.13.

Fo
43、r purposes of information only, thetypes of alloy now commonly used for each of the several alloys are listedbelow. Certain alloys that have a “commercial standing” may have beenassigned a UNS designation (see 1.2). The chemical composition of any ofthe materials shall be within the total range spec

46、mNOTE 3The values of the wire diameters in Table 1 are given to thenearest 0.0001 in. or 0.0001 mm and correspond to the standard sizesgiven in Specification B 258. The use of gage numbers to specify wire sizeis not recognized in these specifications because of the possibility ofconfusion. An excell
47、ent discussion of wire gages and related subjects iscontained in NBS Handbook 100.NOTE 4Other tests than those provided in this specification have beenconsidered at various times, such as twist tests, wrap tests, tests for elasticlimit, etc. It is the opinion of the committee that twist and wrap tes
48、ts onhard-drawn alloy wire do not serve a useful purpose and should beregarded as undesirable, as well as inconclusive as to results andsignificance. Tests for values of elastic limit are likewise indefinite as toresults. Tests to determine elastic properties of hard-drawn wire fromwhich wire string
49、ing and sagging data may be compiled are considered tobe outside the scope of the acceptance tests contemplated in thisspecification.NOTE 5It is known that the rate of loading during tension testing ofcopper and copper alloys affects the performance of the sample to agreater or lesser extent, depending upon many factors. In general, testedvalues of tensile strength are increased and tested values of elongation arereduced with increase of speed of the moving head of the testing machine.These effects are pronounced when the speed of the moving head isexcessive in the tes
