EN 12167:2011 (E) 4 Foreword This document (EN 12167:2011) 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of an identical text or by endorsement, at the latest by December 2011, and conflicting national standards shall be withdrawn at the latest by December 2011.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 or all such patent rights. This document supersedes EN 12167:1998. 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 12167, Copper and copper alloys — Profiles and rectangular bar for general purposes. This is one of a series of European Standards for the copper and copper alloy products rod, wire and profile. 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 12166, Copper and copper alloys — Wire for general purposes; EN 12168, Copper and copper alloys — Hollow rod for free machining purposes; EN 13347, Copper and copper alloys — Rod 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 profiled wire for electrical purposes. In comparison with EN 12167:1998, the following significant technical changes were made: a) Profiles in L-, T-, U-shaped cross-sections incorporated; b) Removal of eighteen materials: 1) Cu-DLP (CW023A) and Cu-DHP (CW024A); 2) CuCr1 (CW105C); 3) CuAl6Si2Fe (CW301G), CuAl7Si2 (CW302G) and CuAl10Fe3Mn2 (CW306G); SIST EN 12167:2011

EN 12167:2011 (E) 7 1 Scope This European Standard specifies the composition, property requirements and dimensional tolerances for copper alloy profiles including L-, T-, U-shaped cross-sections, and bars, finally produced by drawing or extruding. This European Standard applies to profiles with L-, T- and U-shaped cross-sections which would fit within a circumscribing circle of a maximum 180 mm diameter and to bars with thicknesses from 3 mm up to and including 60 mm and with widths from 6 mm up to and including 120 mm.
The sampling procedures, the methods of test for verification of conformity to the requirements of this European Standard, are also specified. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

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 designation 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 specified mechanical properties; R. Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile strength requirement; H. Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirement; S (suffix)
Material condition for a product which is stress relieved. NOTE Products in the M,
R. or H. material condition may be specially processed (i.e. mechanically or thermally stress relieved ) in order to lower the residual stress level to improve the resistance to stress corrosion and the dimensional stability on machining [see 5 h), 5 i) and 8.5]. Exact conversion between material conditions designated R. and H. is not possible. Except when the suffix S is used, material condition is designated by only one of the above designations. 4.3 Product The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product is conveyed in communication. It provides mutual comprehension at the international level with regard to products which meet the requirements of the relevant European Standard. The product designation is no substitute for the full content of the standard. SIST EN 12167:2011
EN 12167:2011 (E) 9 The product designation for products to this standard shall consist of: denomination (profile or bar); number of this European Standard (EN 12167); material designation, either symbol or number (see Tables 1 to 7); material condition designation (see Tables 8 to 14); for profiles, the number of the profile or a fully dimensioned and toleranced drawing; for profiles with L-, T-, U-shaped cross-sections, the nominal cross-sectional dimensions; for bar, the nominal cross-sectional dimensions; for bar and profiles with L-, T-, U-shaped cross-sections , the tolerance class (see Table 15 to 17); for bar, the corner shape (the following designations shall be used as appropriate: SH for sharp, RD for rounded) (see Table 21).
