Copper and copper alloys - Cast unwrought copper products
This European Standard specifies the composition and physical properties of cast unwrought copper products (refinery shapes) in thirteen grades of copper and nine silver-bearing copper grades. The refinery shapes included are horizontally, vertically and continuously cast wire bars, cakes, billets and ingots. Wire bars, cakes and billets are intended for fabricating into wrought products; ingots are intended for alloying in wrought and cast copper alloys. A table indicating the refinery shapes in which each copper grade is normally available is given in Annex A. Annex B gives information on the relationships between electrical resistivity and conductivity of copper.
Kupfer und Kupferlegierungen - Gegossene Rohformen aus Kupfer
Diese Europäische Norm legt die Zusammensetzung und die physikalischen Eigenschaften von gegossenen Rohformen aus Kupfer (Gussformate) für dreizehn Kupfersorten und neun silberhaltige Kupfersorten fest. Die Gussformate umfassen horizontal, vertikal und kontinuierlich gegossene Drahtbarren, Walzplatten, Rund-blöcke und Blockmetalle. Drahtbarren, Walzplatten und Rundblöcke sind zur Herstellung von Knetprodukten, Blockmetalle zum Legieren von Kupfer-Knetlegierungen und Kupfer-Gusslegierungen, vorgesehen.
Eine Tabelle in Anhang A gibt die Gussformate wieder, in denen die jeweilige Kupfersorte üb¬licherweise erhältlich ist. Anhang B beschreibt die Beziehung zwischen spezifischem elektrischen Widerstand und spezifischer elektrischer Leitfähigkeit von Kupfer.
Cuivre et alliages de cuivre - Formes brutes de coulée en cuivre
La présente Norme européenne spécifie la composition et les propriétés physiques des formes brutes de coulée en cuivre en treize nuances de cuivre et neuf nuances de cuivre à l’argent. Les formes brutes de coulée considérées sont des barres à fil, plateaux, billettes et lingots moulés par coulée continue horizontalement ou verticalement. Les barres à fil, plateaux et billettes sont destinés à être transformés en produits corroyés ; les lingots sont destinés à être transformés en alliages de cuivre corroyés et moulés.
Un tableau indiquant les formes brutes de coulée sous lesquelles chaque nuance de cuivre est normalement disponible est donné en Annexe A. L’Annexe B donne des informations sur les relations entre la résistivité électrique et la conductivité du cuivre.

Annex B gives information on the relationships between electrical resistivity and conductivity of copper. 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 1655, Copper and copper alloys — Declarations of conformity EN 10204, Metallic products — Types of inspection documents EN ISO 2626, Copper — Hydrogen embrittlement test (ISO 2626) IEC 60468, Method of measurement of resistivity of metallic materials ISO 4746, Oxygen-free copper — Scale adhesion test 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 unwrought product refinery shape general term for unwrought products obtained by refining or melting and casting processes, intended for further processing EXAMPLE Examples of unwrought products are cathodes, wire bars, cakes, billets, ingots. [SOURCE: ISO 197-2:1983, 2.1] 3.2 wire bar cast unwrought product normally of approximately square cross-section, with or without tapered ends, principally used for rolling into drawing stock or flat products for subsequent processing into wire, strip or profile [SOURCE: ISO 197-2:1983, 2.3] 3.3 cake cast unwrought product of rectangular cross-section, generally used for rolling into plate, sheet, strip or profiles [SOURCE: ISO 197-2:1983, 2.4] SIST EN 1976:2014

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 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 to this standard shall consist of: denomination (Billet, Wire bar, Cake or Ingot); number of this European Standard (EN 1976); material designation, either symbol or number (see Tables 1 to 4); cross-sectional shape (the following designations shall be used as appropriate: RND for round, SQR for square, RCT for rectangular); nominal dimensions (diameter, or width x thickness, and length); nominal unit mass, (if appropriate). SIST EN 1976:2014
EN 1976:2012 (E) 6 The derivation of a product designation is shown in the following example. EXAMPLE Billets conforming to this standard, in material designated either Cu-ETP or CR004A, round cross-section, nominal diameter 250 mm × nominal length 1 000 mm, are designated as follows:
Billet EN 1976 — Cu-ETP — RND 250 × 1 000
