This Euro

19、pean 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of an identical text or by endorsement, at the latest by January 2017, and conflicting national standards shall be withdrawn at the latest by January 2017. Attention is drawn to the possibility that some of the ele

20、ments 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 supersedes EN 12165:2011. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 4 “Extruded and dra

BS EN 12165:2016EN 12165:2016 (E) 6 Introduction The European Committee for Standardization (CEN) draws attention to the fact that it is

29、claimed that compliance with this document may involve the use of a patent concerning the alloy CuZn21Si3P (CW724R) and CuZn33Pb1AlSiAs (CW725R) 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 t

30、hat 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. For CuZn21Si3P (CW724R) information may be obt

31、ained from: Wieland-Werke AG Graf Arco Strae 36 D-89079 Ulm GERMANY For CuZn33Pb1AlSiAs (CW725R) information may be obtained from: Diehl Metall Messing Heinrich-Diehl-Strae 9 D-90552 Rthenbach/Pegnitz GERMANY Attention is drawn to the possibility that some of the elements of this document may be the

32、 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 co

33、ncerning 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

34、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

35、used in any application without any legal restriction. BS EN 12165:2016EN 12165:2016 (E) 7 1 Scope This European Standard specifies the composition, property requirements and dimensional tolerances for forging stock of copper and copper alloys. The sampling procedures and the methods of test for ver

36、ification 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. For dated references, only the edition cited applies.
