This is one of a series of European Standards for products manufactured from refined copper grades. Other products are specified as follows: EN 1977, Copper and copper alloys Copper dra
19、wing stock (wire rod); EN 1978, Copper and copper alloys Copper cathodes. In comparison with the first edition of EN 1976:1998, the following significant changes were made: a) Clause 3, Terms and definitions for the various refinery shapes have been added from ISO 197-2; b) Table 2, Cu-FRHC, Other e

DIN EN 1976:2013-01 EN 1976:2012 (E) 4 1 Scope This European Standard specifies the compositio
23、n 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 int
24、ended 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
25、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 d

31、tions 4.1 Material 4.1.1 General The material is designated either by symbol or number (see Tables 1 to 4). 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
32、 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 patter
33、n 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 t
34、he 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
35、 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). DIN EN 1976:2013-01 EN 1976:2012 (E) 6 The derivation of a product designation is shown in the follow
36、ing 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 or Billet EN 1976 CR004A RND 250 1 000 Denomination Number of
37、 this European Standard Material designation Cross-sectional shape and nominal dimensions in millimetres 5 Ordering information In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order th
38、e following information: a) quantity of product required (mass); b) denomination (Billet, Wire bar, Cake or Ingot); c) number of this European Standard (EN 1976); d) material designation (see Tables 1 to 4); e) cross-sectional shape required; f) nominal dimensions (i.e. diameter, or width thickness,
39、 and length) and nominal mass, where appro-priate (see Table 7 for wire bar dimensions). It is recommended that the product designation, as described in 4.2, is used for items b) to f). In addition, the purchaser shall also state on the enquiry and order any of the following, if required: g) for Cu-
40、ETP and Cu-FRHC only: if oxygen content is higher than 0,040 % (see Table 2, Footnote b); h) for Cu-FRHC only: if the total impurities content is higher than 0,06 % (see Table 2, Footnote d); i) for ingots only: whether they are to be marked with a furnace charge mark; j) the tests, if any, which th
41、e purchaser requires to be carried out by the manufacturer on the product, selected from the tests appropriate to each copper grade given in Table 6; k) whether a declaration of conformity is required (see 9.1); l) whether an inspection document is required, and if so, which type (see 9.2).
