This European Standard shall be given the status of a national standard, either by pu

26、blication of an identical text or by endorsement, at the latest by January 2017, and conflicting national standards shall be withdrawn at the latest by January 2017.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 elements of this document may be the subject of patent rights. CEN shall not be

27、 held responsible for identifying any or all such patent rights. This document supersedes EN 12164:2011. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 4 “Extruded and drawn products, forgings and scrap” to revise the following standard: EN 12164:2011, Copper an

28、d copper alloys Rod for free machining purposes. This document is one of a series of European Standards for the copper and copper alloy products rod, wire, profile and forgings. Other products are specified as follows: EN 12163, Copper and copper alloys Rod for general purposes; EN 12165, Copper and

29、 copper alloys Wrought and unwrought forging stock; EN 12166, Copper and copper alloys Wire for general purposes; EN 12167, Copper and copper alloys Profiles and bars for general purposes; EN 12168, Copper and copper alloys Hollow rod for free machining purposes; EN 13601, Copper and copper alloys C

In comparison with EN 12164:2011, the follo

31、wing significant technical changes were made: a) addition of four new materials: CuZn37Pb1 (CW605N), CuZn35Pb1,5AlAs (CW625N), CuZn33Pb1,5AlAs (CW626N) and CuZn33Pb1AlSiAs (CW725R) due to the market requirements on restriction of lead and modification of the chemical composition for CuZn39Pb1 (CW611

32、N); b) introduction of an optional procedure how to refer to restrictions to the chemical composition imposed by the 4 MS Common Composition List for materials used for products accepted for contact with drinking water; c) requirements and test methods for resistance of dezincification modified; d)

33、provisions for surface quality added; EN 12164:2016 (E) DIN EN 12164:2016-11 5 e) mechanical properties for CuZn21Si3P (CW724R) modified. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard:

EN 12164:2016 (E) DIN EN 12164:2016-11 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

36、(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 that he is willing to negotiate licenses either free of charge or under reasonable and non-discriminatory te

37、rms 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 obtained from: Wieland-Werke AG Graf Arco Strae 36 D-89079 Ulm GERMANY For CuZn33Pb1AlSiAs (CW725R) informatio

38、n 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 subject of patent rights other than those identified above. CEN shall not be held responsible for identify

39、ing 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,

40、 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.

41、 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. EN 12164:2016 (E) DIN EN 12164:2016-11 7 1 Scope Thi

42、s European Standard specifies the composition, property requirements and dimensional tolerances for copper alloy rod, in the shape of circles, squares, hexagons or octagons, finally produced by drawing or extruding, especially intended for free machining purposes. The sampling procedures and the met

43、hods of test for verification of conformity to the requirements of this European Standard are also specified.
