prEN 10264-2:2017 (E) 3 European foreword This document (prEN 10264-2:2017) has been prepared by Technical Committee ECISS/TC 106 “Wire rod and wires”, the secretariat of which is held by AFNOR. This document is currently submitted to the CEN Enquiry. This document will supersede EN 10264-2:2012. EN 10264, Steel wire and wire products - Steel wire for ropes is made up of the following parts: — Part 1: General requirements — Part 2: Cold drawn non alloy steel wire for ropes for general applications — Part 3: Round and shaped non alloyed steel wire for high duty applications — Part 4: Stainless steel wire This European Standard has been technically revised to incorporate the following changes: a) additional standards have been referenced for manufacturing the drawn wires (see Clause 4); b) the purity of the zinc coating of the drawn wire has been specified according to the relevant EN 1179 (see Clause 4); c) other tensile strength grades than those given in Table 1 have been allowed, subject to an agreement between supplier and user at the time of order (see 5.1); d) other wires than those given in Table 1 have been allowed, subject to an agreement between the customer and the supplier at the time of order (see 5.2); e) new values have been given in Table 2 "Requirements for mechanical characteristics of wire". oSIST prEN 10264-2:2017

prEN 10264-2:2017 (E) 4 1 Scope This part of EN 10264 defines cold drawn non alloy steel wire used for the manufacture of: — ropes for general applications and lifts; — ropes for applications for which there is no specific European Standard. This part of EN 10264 does not apply to steel wire taken from manufactured ropes. This part of EN 10264 specifies the following for cold drawn non alloy steel wire for ropes for general applications: — dimensional tolerances; — mechanical characteristics; — requirements relating to the chemical composition of the steel wire; — conditions to be satisfied by any coating. In addition to the requirements of this part of EN 10264, the requirements of EN 10264-1 also apply. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements 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 1179, Zinc and zinc alloys - Primary zinc EN 10218-1, Steel wire and wire products - General - Part 1: Test methods EN 10244-2, Steel wire and wire products - Non-ferrous metallic coatings on steel wire - Part 2: Zinc or zinc alloy coatings EN 10264-1, Steel wire and wire products - Steel wire for ropes - Part 1: General requirements EN ISO 16120-1, Non-alloy steel wire rod for conversion to wire - Part 1: General requirements (ISO 16120-1) EN ISO 16120-2, Non-alloy steel wire rod for conversion to wire - Part 2: Specific requirements for general purpose wire rod (ISO 16120-2) EN ISO 16120-4, Non-alloy steel wire rod for conversion to wire - Part 4: Specific requirements for wire rod for special applications (ISO 16120-4) 3 Product designation The designation of round wire for ropes, covered by this part of EN 10264, shall be based on the nominal diameter (d), surface appearance and tensile strength classification. The abbreviation for the surface finish condition is: — U (uncoated) for bright wire; — A or B for zinc or zinc alloy coating depending on coating class. oSIST prEN 10264-2:2017

prEN 10264-2:2017 (E) 5 A distinction is made between a zinc and a zinc alloy coating by the addition in brackets of “Zn/Al” for the zinc alloy. EXAMPLE 1 Wire for rope for general applications with nominal diameter d = 1,5 mm, surface appearance bright (U), tensile strength grade 1 770 MPa. Designation rope wire EN 10264-2 — 1,5 — U — 1 770 EXAMPLE 2 Wire for rope for general applications with a nominal diameter d = 2,5 mm, zinc coated class A, tensile strength grade 1 370 MPa. Designation rope wire EN 10264-2 — 2,5 — A — 1 370 EXAMPLE 3 Wire for rope for general applications with a nominal diameter d = 1,8 mm, coated with zinc alloy, class B, tensile strength grade 1 770 MPa. Designation rope wire EN 10264-2 — 1,8 — B(Zn/Al) — 1 770 4 General conditions of manufacture The drawn wire shall be manufactured using wire rod in accordance with either EN ISO 16120-1 and EN ISO 16120-2 or EN ISO 16120-1 and EN ISO 16120-4. The finished wire shall show no surface defects or internal defects prejudicial to its use. When specified, drawn wire shall be supplied with zinc coating or Zn95/Al5 coating. Unless otherwise specified, the zinc used for the zinc coating shall have a pu
