DIN EN 1977:2013-04 EN 1977:2013 (E) 4 Introduction Copper drawing stock (wire rod) is normally ma
26、nufactured by one of the following process routes: continuous casting and hot rolling 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 condu
27、ctivity (of copper). Annex B (normative) describes the rapid elongation test method (AR-Test) for diameter 8 mm Cu-ETP1 wire rod. DIN EN 1977:2013-04 EN 1977:2013 (E) 5 1 Scope This European Standard specifies the composition, mechanical, electrical and physical properties for high conductivity copp
28、er drawing stock (wire rod) suitable for fabrication into wire by cold drawing, principally 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 approximate
29、ly circular, in a range of diameters from 6 mm. 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

32、is document, the following terms and definitions apply. 3.1 drawing stock wire rod intermediate solid wrought product, of uniform cross-section along its whole length, supplied in coils 4 Designations 4.1 Material 4.1.1 General The material is designated either by symbol or number (see Tables 1 to 4
33、). 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 requiremen
34、ts are not necessarily the same. 4.1.3 Number The material number designation is in accordance with the system given in EN 1412. DIN EN 1977:2013-04 EN 1977:2013 (E) 6 4.2 Product The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of
35、 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 produ
