EN 1982:2017 (E) 6 Introduction This European Standard for copper alloy ingots, and copper and copper alloy castings is based on previous national standards and harmonizes the compositions and mechanical properties required. This European Standard does not include copper refinery shapes which are intended for working into wrought products and are the subject of EN 1976. Nor does it include master alloys intended for the manufacture of copper alloys which are the subject of EN 1981. The essential information relevant to correct ordering, given in Clause 5 of the standard, is supplemented by Annex A, which is based upon the recommended practice for the ordering and supply of castings given in EN 1559-1. Its purpose is to assist the purchaser in providing full information to the supplier to ensure that he supplies castings according to the purchaser's requirements. It is recommended that full consultation takes place between the purchaser and the supplier at the stages of enquiry and ordering. Sampling and testing frequency, where applicable, are specified in Clause 7. For certain applications, more rigorous inspection procedures may be required. Annex B gives supplementary inspection procedures which may be invoked, at the option of the purchaser [see Clause 5 o)]. Some copper and copper alloys can be used in castings for pressure equipment. Ingots are not suitable for pressure equipment. The permitted material grades of copper and copper alloys for pressure applications and the conditions for their use are given in specific product or application standards. For the design of pressure equipment, specific design rules apply. Annex ZA gives information relating to the conformance of permitted material grades of copper and copper alloys used in castings to the New Approach Pressure Equipment Directive 2014/68/EU. 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-B (CB768S) and CuZn21Si3P-C (CC768S) given in Table H.2 as well as concerning the alloy CuSi4Zn4MnP-B (CB245E) and CuSi4Zn4MnP-C (CC245E) given in Table P.1 as well as concerning the alloy CuSi4Zn9MnP-B (CB246E) and CuSi4Zn9MnP-C (CC246E) given in Table P.2 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-B (CB768S) and CuZn21Si3P-C (CC768S) information may be obtained from Wieland-Werke AG Graf Arco Straße 36 D-89079 Ulm GERMANY SIST EN 1982:2017



EN 1982:2017 (E) 7 — For CuSi4Zn4MnP-B (CB245E), CuSi4Zn4MnP-C (CC245E), CuSi4Zn9MnP-B (CB246E) and CuSi4Zn9MnP-C (CC246E) information may be obtained from VIEGA GmbH and Co. KG Viega Platz 1 D-57439 Attendorn 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 specified in this European Standard may be restricted to the composition 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. SIST EN 1982:2017



EN 1982:2017 (E) 8 1 Scope This European Standard specifies the composition, mechanical properties and other relevant characteristics of copper and copper alloys. The sampling procedures and test methods for the verification of conformity to the requirements of this standard are also specified. This European Standard is applicable to: a) copper alloy ingots intended to be remelted for later processing (e.g. castings); and b) copper and copper alloy castings which are intended for use without subsequent working other than machining. Recommended practice for the ordering and supply of castings is included in Annex A. Optional supplementary inspection procedures for ingots and castings are included in Annex B. NOTE Ingots are not suitable for pressure equipment applications. 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.

EN 1982:2017 (E) 9 Note 1 to entry: Castings are manufactured by the sand, permanent mould, centrifugal, continuous or pressure die casting process. 3.3 cast any of the following: a) product of one furnace melt; or b) product of one crucible melt; or c) product of a number of furnace or crucible melts where these are aggregated and mixed prior to sampling; or d) production corresponding to the intervals between additions to a holding furnace of new furnace or crucible melts (for example in permanent mould casting or pressure die casting); or e) product from a number of consecutive melts of the same alloy through a die, in the case of continuous casting 3.4 batch any of the following: a) number of ingots taken from a single cast; or b) number of castings of the same design produced from a single cast; or c) portion of the output of a continuous caster during a cast 4 Designations 4.1 Material 4.1.1 General The material is designated either by symbol or number (see Annex C to Annex P). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. A suffix -B is added to the designation to identify material in the form of ingots and a suffix -C is added to the designation to identify material in the form of castings (for example CuSn5Zn5Pb2-C). These suffixes also serve to avoid confusion with wrought products of a similar alloy. 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. SIST EN 1982:2017



EN 1982:2017 (E) 10 4.2 Casting process The designations used to indicate the casting processes referred to in this standard are based on those given in ISO 1190-1, as follows: GS sand casting; GM permanent mould casting; GZ centrifugal casting; GC continuous casting; GP pressure die casting. NOTE Pressure die castings are produced by the injection and solidification of molten metal under substantial pressure, typically above 70 bars, into a metal die. The terms “die casting”, “pressure die casting” or “high pressure die casting” are often used for this concept. 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. The product designation for products specified in this standard shall consist of: — denomination (ingot or casting); — number of this European Standard (EN 1982); — material designation, either symbol or number (see Annex C to Annex P); — for castings, the casting process designation (see 4.2); — for castings, the pattern, die or drawing number, as appropriate. The derivation of a product designation is shown in the following examples. SIST EN 1982:2017
