20、Foreword This document (EN 12165:2011) has been prepared by Technical Committee CEN/TC 133 “Copper and copper 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 th
21、e latest by December 2011, and conflicting national standards shall be withdrawn at the latest by December 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any
22、or all such patent rights. This document supersedes EN 12165:1998. 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 12165:1998, Copper and copper alloys Wrought and unwrought
23、forging stock. This 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 12164, Copper and copper alloys Rod for free machining purpo
24、ses; 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 12420, Copper and copper alloys Forgings; EN 13347, Copper and copper alloys Rod
25、 and wire for welding and braze welding; 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 13605, Copper and copper alloys Copper profiles and profil
26、ed wires for electrical purposes. In comparison with EN 12165:1998, the following significant technical changes were made: a) Removal of thirteen materials: 1) CuCr1 (CW105C), CuNi2Be (CW110C) and CuNi3Si1 (CW112C); 2) CuAl6Si2Fe (CW301G), CuAl7Si2 (CW302G) and CuAl9Ni3Fe2 (CW304G); 3) CuNi10Zn42Pb2
27、 (CW402J); 4) CuZn39Pb3Sn (CW615N) and CuZn40Pb2Sn (CW619N); Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 19/09/2011 03:32, Uncontrolled Copy, (c) BSIBS EN 12165:2011EN 12165:2011 (E) 5 5) CuZn25Al5Fe2Mn2Pb (CW705R), CuZn37Pb1Sn1 (CW714R), CuZn39Mn1AlPbSi (CW718R) and CuZn40Mn2Fe1 (CW723R)
28、; b) Addition of four materials: 1) CuZn38Pb1 (CW607N) due to the use for hot stamping applications; 2) CuZn42 (CW510L) and CuZn38As (CW511L) due to the market requirements on restriction of lead; 3) CuZn21Si3P (CW724R) due to the market requirements on restriction of lead; c) Revision of the mechan
29、ical properties (Tables 9 to 16) to reflect market needs; in particular the tensile strength, the 0,2 % proof strength and the elongation that were previously informative have been deleted; d) Modification of the sampling rate (Table 19). According to the CEN/CENELEC Internal Regulations, the nation
30、al standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, N
