20、alloys”, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by January 2017, and conflicting national standards shall be withdrawn at the latest by January 2017.
21、 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12166:2011. Within its programme of work, Technical Committee CEN/TC 133
22、 requested CEN/TC 133/WG 4 “Extruded and drawn products, forgings and scrap” to revise the following standard: EN 12166:2011, Copper and copper alloys Wire for general purposes. This document is one of a series of European Standards for the copper and copper alloy products rod, wire, profile and for
23、gings. Other products are specified as follows: EN 12163, Copper and copper alloys Rod for general purposes; EN 12164, Copper and copper alloys Rod for free machining purposes; EN 12165, Copper and copper alloys Wrought and unwrought forging stock; EN 12167, Copper and copper alloys Profiles and bar
24、s for general purposes; EN 12168, Copper and copper alloys Hollow rod for free machining purposes; EN 13601, Copper and copper alloys Copper rod, bar and wire for general electrical purposes; EN 13602, Copper and copper alloys Drawn, round copper wire for the manufacture of electrical conductors; EN
25、 13605, Copper and copper alloys Copper profiles and profiled wire for electrical purposes. In comparison with EN 12166:2011, the following significant technical changes were made: a) introduction of an optional procedure how to refer to restrictions to the chemical composition imposed by the 4 MS C
26、ommon Composition List for materials used for products accepted for contact with drinking water; b) provisions for surface quality added. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard:

BS EN 12166:2016EN 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 c
29、oncerning 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
30、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 Strae 36 D-89079 Ulm GERMANY Attention is drawn to the possibility that some of the elemen
31、ts 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
32、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 contac
33、t 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 i
34、mply that the material can be used in any application without any legal restriction. BS EN 12166:2016EN 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
35、, 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 n

41、on system given in ISO 1190-1. NOTE Although material symbol designations used in this standard might be the same as those in other standards using the designation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same. 4.1.3 Number The material number designa
42、tion is in accordance with the system given in EN 1412. 4.2 Material condition For the purposes of this standard, the following designations, which are in accordance with the system given in EN 1173, apply for the material condition: M material condition for the product as manufactured, without spec
