Mechanical Properties6.1 The coppered steel wire shall meet the tensile strengthrequirements shown in Table 1 when tested in accordance withMethods A370.6.2 Test specimens found to cont
16、ain a weld or an obviousdefect shall be discarded and another test specimen obtained toverify conformance to the tensile strength requirements.7. Dimensions and Tolerances7.1 The permissible variation in diameter of the copperedwire as represented by the test specimens shall be as indicatedin Specif
17、ication A510.8. Coating Requirements8.1 Due to the nature of the process, the thickness of thecopper coating is extremely thin. Therefore, there is norequirement for thickness of coating; the requirement is that thecoating be continuous.8.2 The coppered wire as represented by the test specimensshall
18、 be capable of being wrapped in a close helix at a rate notexceeding 15 turns/min around a cylindrical steel mandrelhaving a diameter equal to the diameter of the coated wirewithout cracking or flaking the copper coating to such an extentthat any copper can be removed by rubbing with the barefingers
19、. Loosening or detachment during the adhesion test ofsuperficial, small particles of copper formed by mechanicalpolishing of the surface of the coppered wire shall not beconsidered cause for rejection.9. Workmanship9.1 The coppered wire shall be free of slivers, scale, andother imperfections that wo
20、uld be detrimental to intended use.The copper coating shall be continuous and reasonably smooth.To ensure large continuous length coils, welds may be presentin the finished wire.10. Number of Tests and Retests10.1 Alot shall consist of all of the coils of wire of the samesize, type and class, and sh
21、all be offered for inspection at onetime. A wire sample of sufficient length, approximately 4 ft.(1.2 m), shall be cut from either end of each coil selected fortests described in Sections 6, 8 and 9.10.2 The number of test specimens taken from the ends ofcoils during production to assure compliance
22、with Sections 6and 7 varies with the quality control procedures and themanufacturing facilities of each manufacturer, but is generallynot less than 10 % of the coils produced. For the purpose offinal product testing, one specimen from every ten coils orfraction thereof in a lot shall be selected at
23、random, or a totalof seven specimens, whichever is less.10.3 Should one or more of the wire specimens fail anyrequirement, the lot shall be subjected to retest. For retestpurposes the original lot shall be regrouped into 50 coil lots orfractions thereof. Each lot shall be tested for the property inw
24、hich the original sample failed to comply at a frequency of10 % or more so that the total number of tests is at least doublethe original. Any lot that exhibits a failure shall be rejected. Ifduring retesting an additional quality parameter is observed tobe defective, the lot of 50 is subject to reje
25、ction for that cause.The manufacturer may test each coil in the failed lot for theproperty in which failure occurred and reject only the noncon-forming coils.11. Inspection11.1 The manufacturer shall afford the inspector represent-ing the purchaser all reasonable facilities to satisfy that themateri
26、al is being furnished in accordance with this specifica-tion. All tests and inspections shall be made at the place ofmanufacture prior to shipment, unless otherwise specified, andshall be so conducted as not to interfere with the operation ofthe works.12. Rejection and Rehearing12.1 Any rejection by
27、 the purchaser shall be reported to themanufacturer within a reasonable time from receipt of material.12.2 The material must be adequately protected and cor-rectly identified in order that the manufacturer may make aproper investigation.TABLE 1 Tensile Strength RequirementsWire Diameter,in.
