38、fter drawing and before coating. Such a weld shall not be less than 100 m from either end of the coil. No weld shall be made after drawing on grades 85, 105, 125, 145 and 165. 7 Requirements 7.1 Mechanical properties 7.1.1 Tensile strength The tensile strength of the wires measured on the actual dia
39、meter shall be as given in Table 1 for the appropriate grade. Table 1 Tensile strength of wire grades Grade Tensile strength range N/mm2 34 340 Rm 540 65 650 Rm 850 85 850 Rm 1 050 105 1 050 Rm 1 250 125 1 250 Rm 1 450 145 1 450 Rm 1 650 165 1 650 Rm 1 900 NOTE 1 If other minima are ordered a 200 N/
40、mm2 range shall apply. NOTE 2 If tensile strength minima are ordered other than those specified and the tensile strength of the ordered grade is less than or equal to 100 N/mm2 above the minimum tensile strength of the nearest lower specified grade then the properties of that grade shall apply. If t
41、he minimum tensile strength of the required grade is more than 100 N/mm2 above the minimum tensile strength of the nearest lower specified grade then the higher grade properties shall apply. 7.1.2 Elongation Elongation measured after fracture shall be not less than that given in Tables 2, 3 or 4 for
42、 the grade and diameter of wire being tested. 7.1.3 Torsion When tested in accordance with 10.3.1, the wire shall withstand without breaking not less than the minimum number of turns given in Tables 2, 3 and 4 for the wire being tested.

A test sample of grade 165 s
44、hall withstand being closely wrapped around two times its own diameter. No sign of fracture of the base metal shall be evident. 7.2 Nominal diameters and tolerances The preferred nominal diameters of finished wire and the tolerances on diameter shall be as specified in Tables 2, 3 and 4, depending o
45、n the tensile grades. NOTE The tolerances correspond to T1 of EN 10218-2 (Table 1). It is recognized that thick coatings, obtained in the hot dip process, may not be entirely free from surface irregularities, and, provided the latter do not go beyond the limits of good practice, (i.e. isolated and n
46、ot of a repetitive nature), they shall not be a cause for rejection. Persistent lumpy galvanizing or bambooing shall be cause for rejection.

NOTE 2 Grade 34 steel wire may in time exhibit changes in mechanical properties after manufacture, particularly tensile strength and elongation
49、. These changes result from a phenomenon known as strain ageing or strain age hardening, and lead to an increase in tensile strength and a decrease in elongation, compared to the wire immediately after coating with zinc. It is customary to carry out tests immediately after manufacture. At ordinary temperatures, strain ageing may proceed slowly. There
