This European Standard shall be given the status of a

13、national standard, either by publication of an identical text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at the latest by July 2012.

14、 rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes 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 Regul

15、ations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Mal

BS EN 10218-2:2012EN 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 w

17、ire cut to length, for bright steel wire, (i.e. uncoated), metallic coated steel wire and non-metallic coated steel wire. 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 fol

18、lowing referenced documents are indispensable for the application of this document. For dated references, only the edition 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

19、definitions For the purposes of this document, the following terms and definitions apply. 3.1 wire product of constant 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 s

20、ection is generally round, though sometimes oval, rectangular, square, hexagonal, octagonal or other convex section. 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

21、.g. with zinc, copper, nickel or plastic materials). NOTE 3 Heat treatments and/or surface treatments may be carried 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 wi

22、th metallic or non-metallic coatings or both.The metallic coating can be as a finished coating or as a drawn finished coating. 3.2 cut length straightened piece of wire cut to a specified length BS EN 10218-2:2012EN 10218-2:2012 (E) 5 4 Wire diameter tolerance 4.1 Tolerance on diameter of uncoated a

24、relevant tables in this standard. NOTE 1 Diameter tolerances may vary when cut lengths are supplied by a third party. 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, wher

25、e existing, the metallic coating) The purchaser or the product standard shall indicate the tolerance range required 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 p

26、roperties of the wire in the respective product standard, taking into account the influence of the coating thickness (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 ge

27、nerally be used for other galvanised wire, and T3, T4 and T5 would generally be used for bright drawn wire in increasing order of precision required. BS EN 10218-2:2012EN 10218-2:2012 (E) 6 4.1.2 Out of roundness (ovality) The out of roundness is the difference between maximum and minimum diameter o

28、f the wire at any cross-section and shall not be more than one half of the total tolerance given in Table 1. 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

The purchaser shall select the appropriate class required. Figure 3 illustra
