FprEN 12167:2015 (E) 5 European foreword This document (FprEN 12167:2015) has been prepared by Technical Committee CEN/TC 133 “Copper and copper alloys”, the secretariat of which is held by DIN. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 12167:2011. 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 12167:2011, Copper and copper alloys — Profiles and bars for general 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 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 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 12167:2011, the following 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 (CW611N); 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) provisions for surface quality added; e) mechanical properties for CuZn21Si3P (CW724R) modified. kSIST FprEN 12167:2015



FprEN 12167:2015 (E) 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 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 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 obtained from: Wieland-Werke AG Graf Arco Straße 36 D-89079 Ulm GERMANY — For CuZn33Pb1AlSiAs (CW725R) information may be obtained from: Diehl Metall Messing Heinrich-Diehl-Straße 9 D-90552 Röthenbach/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 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, 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. 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. kSIST FprEN 12167:2015



FprEN 12167:2015 (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 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. For undated references, the latest edition of the referenced document (including any amendments) applies.

FprEN 12167:2015 (E) 8 3.2 bar straight product of uniform rectangular cross-section along its whole length 4 Designations 4.1 Material 4.1.1 General The material is designated either by symbol or by number (see Tables 1 to 7). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. 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.
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 Clause 5 list entry i), list entry j) 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 can be 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. kSIST FprEN 12167:2015



FprEN 12167:2015 (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); — DW for compliance in the chemical composition according to 4 MS Common Composition List. This information is mandatory in the case in which the product is used for drinking water applications according to 4 MS Common Composition List and not to be given in other cases; — 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). The derivation of a product designation is shown in in the following examples.
