16、012) has been prepared by Technical Committee ECISS/TC 106 “Wire rod and wires”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2012, and conflicti
17、ng national standards shall be withdrawn at the latest by July 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document sup
18、ersedes EN 10218-2:1996. The standard will comprise the following parts: Part 1: Test methods; Part 2: Wire dimensions and tolerances. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Aus
19、tria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
20、Kingdom. DIN EN 10218-2:2012-03 EN 10218-2:2012 (E) 4 1 Scope This European Standard specifies the tolerances on diameter of round wire and, where applicable, on the length of round wire cut to length, for bright steel wire, (i.e. uncoated), metallic coated steel wire and non-metallic coated steel w
21、ire. This European Standard should not be applied where other requirements for dimensions and tolerances are specified in a particular product standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the ed
22、ition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 10079:2007, Definition of steel products 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 wire product of constan
23、t full cross section along its length, obtained by cold drawing rod through a reducing die or passing under pressure between rollers and rewinding the drawn product NOTE 1 The cross section is generally round, though sometimes oval, rectangular, square, hexagonal, octagonal or other convex section.
24、NOTE 2 The manufacturing processes give close control of geometric (size, surface condition) and mechanical properties. Wire may be supplied uncoated (as drawn, annealed) or coated (e.g. with zinc, copper, nickel or plastic materials). NOTE 3 Heat treatments and/or surface treatments may be carried
25、out during the course of manufacture to improve the properties of wire. EN 10079:2007 NOTE 4 As well as being supplied in the uncoated (bright) condition, wire can also be supplied with metallic or non-metallic coatings or both.The metallic coating can be as a finished coating or as a drawn finished
26、 coating. 3.2 cut length straightened piece of wire cut to a specified length DIN EN 10218-2:2012-03 EN 10218-2:2012 (E) 5 4 Wire diameter tolerance 4.1 Tolerance on diameter of uncoated and metallic coated round steel wire 4.1.1 General Key 1 metallic coating thickness in mm d overall diameter in m
27、m (including, where existing, the metallic coating) Figure 1 For Table 1 Diameter measurements shall be made at any cross-section and shall not differ from the tolerances specified in the relevant tables in this standard. NOTE 1 Diameter tolerances may vary when cut lengths are supplied by a third p
28、arty. NOTE 2 Diameter tolerances are calculated as follows: T1 = 0,035 d T2 = 0,027 d T3 = 0,021 d T4 = 0,015 d T5 = 0,010 d where d is the overall diameter measured in mm (including, where existing, the metallic coating) The purchaser or the product standard shall indicate the tolerance range requi
29、red from Table 1. The overall diameter shall be within the relevant tolerance range given in Table 1; the producer will adapt processing parameters to ensure compliance with the required properties of the wire in the respective product standard, taking into account the influence of the coating thick
30、ness (if applicable). NOTE 3 Unless otherwise specified on the order/enquiry or the product standard, tolerances class T1 would generally be used for heavy galvanised (A) wire, T2 would generally be used for other galvanised wire, and T3, T4 and T5 would generally be used for bright drawn wire in in

DIN EN 10218-2:2012-03 EN 10218-2:2012 (E) 6 4.1.2 Out of roundness (ovality) The out of roundness is the difference between maximum and minimum diameter of the wire at any cross-section and shall not be more than one half of the total tolerance given in Table 1
32、. For diameters d from 0,050 mm to 25,00 mm, the tolerances on diameter shall be as follows: Table 1 Diameter tolerances Dimensions in millimetres Diameter tolerance Wire diameter range mm d T1 T2 T3 T4 T5 0,003 0,050 d 1 000 0,10 % DIN EN 10218-2:2012-03 EN 10218-2:2012 (E) 9 5.2 Tolerance and stra
33、ightness There are three classes of straightness of cut lengths given in Table 4 for wire diameters specified in Table 5. The purchaser shall select the appropriate class required. Figure 3 illustrates the measurement of out of straightness. Table 4 Tolerance of straightness of cut lengths Class L a
34、= 500 mm L a= 1 000 mm Rolling test 1 a = 0,5 mm a = 2 mm will roll down an incline of 1 in 10 2 a = 1,0 mm a = 4 mm 3 No requirementaTest length. For classes 1 and 2, the cut lengths shall also meet the requirements of the rolling test which is performed on a smooth glass incline. Cut lengths are p
35、laced on the incline to allow free rolling. Table 5 Straightness test lengths Wire diameter d mm Test length L mm 2,00 d 6,00 500 6,00 d 13,00 500 or 1 000 NOTE Wire of less than 2,00 mm diameter has insufficient rigidity in length making the measurement a difficult. The test should be agreed betwee
36、n purchaser and supplier. Key a Out of straightness in mm. This is measured at the mid point of the test sample length and a is the distance from the inside of the wire to the straight edge. L Length in mm Figure 3 Measurement of out of straightness 6 Length of wire in coil With a wire of known size and density, the length of the coil can be computed having weighed the mass of the coil.
