39、of each piece shall be shown on the tag.20. Keywords20.1 coated steel wire; high strength steel wire; steel corewire; steel wire; zinc-coated steel wireTABLE 6 Permissible Variations in Diameter of Zinc-Coated Steel WireNOTE 1It is recognized that the surface of zinc coatings, particularly those pro
40、duced by the hot-dip method of coating, are not perfectly smooth anddevoid of irregularities. If the tolerances shown in the table are rigidly applied to such irregularities that are inherent to the product, unjustified rejectionsof wire that would actually be satisfactory for use could occur. It is
41、 intended that these tolerances be used in gaging the wires where there is a minimumof such diameter irregularities due to galvanizing.Specified Diameter Permissible Variationin. mmin. mmPlus Minus Plus Minus0.0500 to 0.0749, incl 1.270 to 1.902, incl 0.0015 0.001 0.038 0.0250.0750 to 0.1199, incl 1
