12、3 “Copper and copper alloys”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2017, and conflicting national standards shall be withdrawn at the latest
13、 by May 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1412:1995. In comparison with EN 1412:1995, the following s
14、ignificant changes were made: a) allocation of ranges for the numeric part of a material number to material groups; b) addition of provisions how to assign the numeric part of a material number to individual materials; c) removal of the provisions for not standardized materials. According to the CEN
15、-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungar

BS EN 1412:2016EN 1412:2016 (E) 4 Introduction The numbering system described in this European Standard is
17、an alternative to the material symbol designation system given in ISO 1190-1. BS EN 1412:2016EN 1412:2016 (E) 5 1 Scope This European Standard establishes a numbering system for designation copper or copper alloys manufactured and/or used in Europe and the responsibility for the allocation and admin
18、istration of numbers for individual copper materials. The system is applicable to copper materials standardized in European Standards. 2 Terms and definitions For the purposes of this document, the following term and definition applies. 2.1 copper material general term for copper and copper alloys 3
19、 Details of the system 3.1 General The number shall be composed of alphabetic (upper case Latin letters) and numeric (Arabic) characters. The system shall provide only one number for each material. A number assigned to an individual material shall not be assigned to another material even if the firs
20、t mentioned material has been withdrawn. 3.2 Structure of numbers 3.2.1 Complete number The number shall consist of six characters. 3.2.2 Position of characters 3.2.2.1 General The positions of characters are as follows: 1 2 3 4 5 6 3.2.2.2 Position 1 The character for the first position shall be th
21、e letter “C” to designate copper material. 3.2.2.3 Position 2 The character for the second position shall be one of the following letters, whose significance is given as follows: B materials in ingots form for remelting to produce cast products; C materials in the form of cast products; F filler mat
22、erials for brazing and welding; M master alloys; R refined unwrought copper; S materials in the form of scrap; BS EN 1412:2016EN 1412:2016 (E) 6 W materials in the form of wrought products. 3.2.2.4 Position 3 to 5 The character for the third, fourth and fifth positions shall be a number from the ran
23、ge allocated to one of the material groups given in Table 1. There is no particular significance attributed to any of these characters within one range. The same number shall be assigned to materials with the same chemical composition (e.g. material in the form of wrought products and the same mater
24、ial in form of scrap). Materials with a different chemical composition shall not be assigned to the same number, unless the materials are in a direct process flow (e.g. material in ingots form for remelting to produce cast products and the corresponding material in form of cast products). 3.2.2.5 Po
25、sition 6 The character for the 6th position shall be a letter designating one of the material groups given in Table 1. There is no particular significance attributed to any of these letters within one material group. 3.2.2.6 Examples CW024A; CB752S; CC383H. 4 Allocation and administration of materia
26、l numbers NOTE CEN/TC 133 is responsible for the allocation and administration of material numbers. Table 1 Significance of positions 3 to 6 Material group Position 3, 4 and 5a(a number in the range) Position 6 (letter designating material group) Copper 000 to 099 A or B Copper alloys, low alloyed (
27、less than 5 % alloying elements) 100 to 199 C or D Miscellaneous copper alloys (5 % or more alloying elements) 200 to 299 E or F Copper-aluminium alloys 300 to 349 G Copper-nickel alloys 350 to 399 H Copper-nickel-zinc alloys 400 to 449 J Copper-tin alloys 450 to 499 K Copper-zinc alloys, binary 500
28、 to 599 L or M Copper-zinc-lead alloys 600 to 699 N or P Copper-zinc alloys, complex 700 to 799 R or S aRange of 800 to 999 to be used as a reserve.
