BS EN 1977:2013EN 1977:2013 (E) 4 Introduction Copper drawing stock (wire rod) is normally manufactured by one of the following process routes: continuous casting and hot rolling

23、 in tandem; continuous or semi-continuous casting and cold rolling; rolling of wire bar or billets; or extrusion. Annex A (informative) gives information on the relationships between electrical resistivity and conductivity (of copper). Annex B (normative) describes the rapid elongation test method (

24、AR-Test) for diameter 8 mm Cu-ETP1 wire rod. BS EN 1977:2013EN 1977:2013 (E) 5 1 Scope This European Standard specifies the composition, mechanical, electrical and physical properties for high conductivity copper drawing stock (wire rod) suitable for fabrication into wire by cold drawing, principall

25、y for the manufacture of electrical conductors. This European Standard covers drawing stock (wire rod), in nine grades of copper and nine silver-bearing copper grades. Normally, the cross-section is approximately circular, in a range of diameters from 6 mm. 2 Normative references The following docum

26、ents, 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.

30、n 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 accord

31、ance with the system given in EN 1412. BS EN 1977:2013EN 1977:2013 (E) 6 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

32、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 European Standard shall consist of: denomination (copper drawing stock); number of

33、this European Standard (EN 1977); material designation, either symbol or number (see Tables 1 to 4); nominal diameter; nominal coil mass; surface condition (the following designations shall be used, as appropriate: M for as manufactured, CL for cleaned). The derivation of a product designation is sh

34、own in the following example. EXAMPLE Drawing stock (wire rod) conforming to this standard, in material designated either Cu-ETP or CW004A, nominal diameter 8 mm, in 1 000 kg coils, cleaned surface condition, shall be designated as follows: Copper drawing stock EN 1977 Cu-ETP 8 1 000 CL or Copper dr

35、awing stock EN 1977 CW004A 8 1 000 CL Denomination Number of this European Standard Material designation Nominal diameter in millimetres Nominal coil mass in kilograms Surface condition BS EN 1977:2013 EN 1977:2013 (E) 7 5 Ordering information In order to facilitate the enquiry, order and informatio

36、n of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information: a) quantity of product required (mass or number of coils); b) denomination (copper drawing stock); c) number of this European Standard (EN 1977); d) material de

37、signation (see Tables 1 to 4); e) nominal diameter; f) nominal coil mass; g) surface condition (see 6.8). It is recommended that the product designation as described in 4.2 is used for items b) to g). In addition, the purchaser shall also state on the enquiry and order any of the following, if requi

38、red: h) whether joins are permitted in the coils (see 6.9); i) additional tests, if any, which the purchaser requires to be carried out by the manufacturer on the material, selected from the tests appropriate to each copper grade given in Table 5; j) whether a declaration of conformity is required (

39、see 9.1); k) whether an inspection document is required, and if so which type (see 9.2). EXAMPLE Ordering details for 5 000 kg of drawing stock conforming to EN 1977, in material designated either Cu-ETP or CW004A, nominal diameter 8 mm, in 1 000 kg coils, cleaned surface condition: 5 000 kg Copper

41、ion of 30 %. The test shall be carried out in accordance with 8.2. No elongation requirements are specified for cold-finished drawing stock. If such requirements are necessary, they should be agreed between the purchaser and the supplier. 6.3 Electrical properties The maximum volume resistivity at 2

42、0 C of hot-finished drawing stock shall conform to the appropriate requirements given in Table 6. The test shall be carried out in accordance with 8.3.
