33、165:2016-11 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) and CuZn33Pb1AlSiAs (CW725R) given in 6.1. CEN takes no position conc
34、erning 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
35、statement of the holder of this patent right is registered with CEN.

36、henbach/Pegnitz 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 pa
37、tents 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
38、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
39、, 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. EN 12165:2016 (E) DIN EN 12165:2016-11 7 1 Scope This European Standard specifies the composition, property requirements and dimen
40、sional tolerances for forging stock of copper and copper alloys. 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 refer
