EN 12166:2016 (E) 6 Introduction The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning the alloy CuZn21Si3P (CW724R) given in 6.1. CEN takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has ensured the CEN that he is willing to negotiate licenses either free of charge or under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with CEN. Information may be obtained from: Wieland Werke AG Graf Arco Straße 36 D-89079 Ulm GERMANY Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above. CEN shall not be held responsible for identifying any or all such patent rights. CEN and CENELEC maintain online lists of patents relevant to their standards. Users are encouraged to consult the lists for the most up to date information concerning patents (ftp://ftp.cencenelec.eu/EN/IPR/Patents/IPRdeclaration.pdf). Due to developing legislation, the composition of a material may be restricted to the composition specified in this European Standard with respect to individual uses (e.g. for the use in contact with drinking water in some Member States of the European Union). These individual restrictions are not part of this European Standard. Nevertheless, for materials for which traditional and major uses are affected, these restrictions are indicated. The absence of an indication, however, does not imply that the material can be used in any application without any legal restriction. SIST EN 12166:2016



EN 12166:2016 (E) 7 1 Scope This European Standard specifies the composition, property requirements and dimensional tolerances for copper alloy wire, finally produced by drawing, rolling or extruding, intended for general purposes, spring and fastener manufacturing applications. The sampling procedures and the methods of test for verification of conformity to the requirements of this European Standard are also specified. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 12166:2016 (E) 13 6 Requirements 6.1 Composition The composition shall conform to the requirements for the appropriate material given in Tables 1 to 6. Due to developing legislation, specific applications (see 4.3) may require restrictions in the chemical composition. In this case the limitations shall be specified in the ordering information [see Clause 5 list entry f)]. 6.2 Mechanical properties The tensile properties of R. material condition or the hardness properties of H. material condition shall conform to the appropriate requirements given in Tables 7 to 12. The tests shall be carried out in accordance with 8.2 or 8.3. 6.3 Grain size The grain size of G. material condition shall conform to the appropriate ranges in Table 13. The tests shall be carried out in accordance with 8.4. 6.4 Dimensions and tolerances 6.4.1 Diameter or width across-flats The diameter or width across-flats shall conform to the tolerances given in Tables 14 to 16. NOTE The diameter of round wire is calculated as the mean of one or more pairs of measurements taken at right angles at the same cross-section of the wire. 6.4.2 Shape tolerances for round wire The deviation from circular form of round wire less than 3,0 mm diameter, shall not exceed half the range of the tolerance on diameter given in Table 14. The deviation from circular form of round wire equal to or greater than 3,0 mm diameter, shall not exceed the range of the tolerance on diameter given in Table 14. 6.4.3 Corner and edge geometry (wire with square and rectangular cross-section only) The radii of the corners of wires shall conform to the requirements given in Table 17 for sharp or rounded corners. For wires with the minimum width across-flats less than 3 mm the corners shall be calculated according to Figure 1. For wires with both widths across-flats equal to or greater than 3 mm, except in cases of dispute, the corners shall be measured directly, either by use of a gauge or an optical projector. In cases of dispute the method by optical projector shall be used. Wire edges shall be smooth along the product length without discontinuity. SIST EN 12166:2016
