This European Standard shall be given the status of a national standard, either by publication of an identical text or b
13、y endorsement, at the latest by October 2008, and conflicting national standards shall be withdrawn at the latest by October 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible fo
14、r identifying any or all such patent rights. This document supersedes EN 1173:1995. Within its programme of work, Technical Committee CEN/TC 133 decided to prepare the revision of the fol-lowing standard: EN 1173:1995, Copper and copper alloys Material condition or temper designation In comparison w
15、ith the first edition of EN 1173:1995, the following significant technical changes were made: title has been changed, the term “temper” has been withdrawn; examples in Clause 4 have been completed; alloy designation in 4.10 has been corrected. According to the CEN/CENELEC Internal Regulations, the n
16、ational standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Repub-lic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norw

DIN EN 1173:2008-08 EN 1173:2008 (E) 4 1 Scope This European Standard establishes a system for designation of material conditions to be used for the identifica-tion of mandatory property requirement
18、s. These designations are applicable to wrought products of copper and copper alloys. 2 Basis of designation system The material condition designation is based on the mandatory property requirement(s), the level of property re-quired and if necessary, any special additional treatment. 3 Structure of
19、 designation 3.1 General The material condition designation usually consists of four characters. In position 1 there shall be a letter and in positions 2 to 4 there shall be figures. A further figure shall be added in position 5 or, in the case of additional treatment, a suffix letter shall be added
20、 in position 5 or 6. Only one designation is allowed for a certain material condition and the whole size range, for which the minimum requirement applies. 3.2 Position 1 Position 1 indicates the designating mandatory property, specified in the appropriate European product standard, by one capital le
21、tter of the alphabet. The use of a letter indicating the designating mandatory property does not preclude the combination of two or more mandatory properties if specified in the appropriate product standard. Letters shall be used in accordance with Table 1. Table 1 Letters for Position 1 Letter Desi
22、gnating mandatory property A Elongation B Spring bending limit D As drawn, without specified mechanical properties G Grain size H Hardness (Brinell or Vickers) M As manufactured, without specified mechanical properties R Tensile strength Y 0,2%-proof strength NOTE The manufacturing process including
23、 heat treatment is not indicated by these letters. DIN EN 1173:2008-08 EN 1173:2008 (E) 5 3.3 Positions 2 to 4 Except for designations D, G and M, positions 2 to 4 consist of a three digit figure to designate the minimum value of the mandatory property specified in the European product standard. Des
24、ignations D and M are not fol-lowed by any further characters. For designation G, positions 2 to 4 consist of a three digit figure to designate the mid-range value of the mandatory property specified in the European product standard. In the case of a value of two significant digits a zero “0“ is to
25、be indicated at position 2 in front of the value speci-fied, e.g. for hardness. In the case of a value of one significant digit, zeros are to be indicated at positions two and three in front of the value specified, e.g. for elongation. 3.4 Positions 5 and 6 If necessary a four digit figure may be in
26、dicated by use of the additional position 5, e.g. for very high tensile strength of precipitation hardened alloys. If an additional treatment is applicable for the purpose of stress relieving a product, the suffix “S“ is added in position 5 or 6. 4 Examples 4.1 General The material condition designa
27、tion is intended to be used in product designation and ordering information. In the product designation the material condition designation shall follow the material designation and be separated from it by a hyphen (“). Some examples of material condition designations in accordance with this standard
