Keywords20.1 coated steel wire; high strength steel wire; steel corewire; steel wire; zinc-coated steel wireEXPLANATORY NOTESNOTE 1Steel wire cannot be produced to exact specified lengths.Since welding of steel wires for use in electrical
45、 conductors is notaccepted, the random lengths of wire that result from normal productioncan result in otherwise good product being rejected and scrapped. In orderto reduce cost, the purchaser and manufacturer should, at the time ofpurchase, have an agreed upon method to permit the acceptance of odd
46、lengths of steel wire.Atypical agreement would be to permit lengths otherthan the specified length for up to 5 % of the purchased quantity with anysingle piece being not less than 50 % of the specified length.SUMMARY OF CHANGESCommittee B01 has identified the location of selected changes to this sta
47、ndard since the last issue (B606 02)that may impact the use of this standard. (Approved Nov. 1, 2008.)(1) Section 3, Added “product code” definition.(2) Section 13, Simplified how diameter measurement is madeand recorded.(3) Metric tables, Separated metric units into stand alone tablesand modified d
48、iameter metric ranges to match other steel wirestandards.TABLE 10 Permissible Variations in Diameter of Zinc-CoatedSteel WireNOTE 1It is recognized that the surface of zinc coatings, particularlythose produced by the hot-dip method of coating, are not perfectly smoothand devoid of irregularities. If
49、 the tolerances shown in the table are rigidlyapplied to such irregularities that are inherent to the product, unjustifiedrejections of wire that would actually be satisfactory for use could occur.It is intended that these tolerances be used in gaging the wires where thereis a minimum of such diameter irregularities due to galvanizing.Specified Diameter Permissible Variation, in.in.
