3、0-01SupersedesDIN EN 15085-3:2008-01www.beuth.deDocument comprises pages53DIN EN 15085-3:2010-01 National foreword This standard has been prepared by Technical Committee CEN/TC 256 “Railway applications” (Secretariat: DIN, Germany) in collaboration with Technical Committee CEN/TC 121 “Welding and al
4、lied processes”. The responsible German body involved in its preparation was the Normenausschuss Fahrweg und Schienenfahrzeuge (Railway Standards Committee), Working Committee NA 087-00-12 AA Werkstoffe, Fge- und Verbindungstechnik. The EN 15085-1 to EN 15085-5 series of European Standards replaces
5、the DIN 6700-1 to DIN 6700-6 series of German national standards, with European Standard EN 15085-3 replacing the German national standards DIN 6700-3, DIN 6700-5 and parts of DIN 6700-6; however, the European Standard does not describe the evaluation or determination of the stress factor. Safety ca
6、tegories The safety categories defined in 4.5 are in accordance with DIN 6700-1. In Germany these categories are determined taking the information in Annex G of the present standard into consideration if no other classification is required by the national railway authority or by the customer. Weld p
7、erformance classes The new classification into weld performance classes and their correlation with the new weld inspection classes involve modifications to DIN 6700. Use of existing design drawings and weld planning documents Because classification into weld performance classes is still based on str
8、ess factors and safety categories, design drawings and weld planning documents drawn up in accordance with DIN 6700 can be converted using cross-reference and/or recoding tables developed by the welding manufacturer. Existing design drawings or weld planning documents may continue to be used if so a
9、greed with the customer and the national railway authority. Reference shall be made to the cross-reference and/or recoding tables used. Further explanatory notes and details regarding the conversion of existing design drawings are given in the technical bulletin DVS 1623. This document also compares
10、 the quality requirements specified in DIN EN 15085-3 with those given in previous technical rules issued by the German national railway (DB, or Deutsche Bahn), the state-owned railway of the former German Democratic Republic (DR, or Deutsche Reichsbahn) and the DIN 6700 series. Welding coordination
11、 At his discretion, the responsible welding coordinator may delegate tasks to a deputy coordinator designated by him, in which case the specifications of Annex B of DIN EN 15085-2:2008 are to be taken into account. Annex H “Welding of 6000 series aluminium alloy extrusions Recommendations from the A
12、ljoin project for improved crashworthiness” This Annex may only be used in conjunction with the recommendations of the Aljoin research project, see 5 and 6. The DIN Standard corresponding to the International Standard referred to in clause 2 is as follows: ISO 10447 DIN EN ISO 10447 2 DIN EN 15085-3
13、:2010-01 Amendments This standard differs from DIN 6700-3:2003-02, DIN 6700-5:2002-05 and DIN 6700-6:2000-08 as follows: a) The content has been updated to reflect the current state of technology and harmonized with European and international standardization. b) The classification into weld performa
14、nce classes has been changed. The classes are now designated as CP A, CP B, CP C1, CP C2, CP C3 and CP D. c) The weld performance classes CP B to CP D correspond to the equivalent quality levels for imperfections as specified in the relevant EN ISO Standards. Weld performance class CP A is an additi
15、onal quality level. d) The weld performance classes are correlated with weld inspection classes which indicate the type and scope of weld testing, see DIN EN 15085-5. Compared with DIN EN 15085-5-3:2008-01, the following corrections have been made to the German version only and therefore do not affe
16、ct the English text: e) The table for converting DIN 6700 weld performance classes into EN 15085 classes given in the National Annex NA has been deleted because it led to problems of interpretation as regards the correlation of the classes. f) The explanatory notes on weld performance classes in the

DIN EN 15085-3:2010-01 EN 15085-3:2007 (E) 6 Introduction Welding is a
43、 special process in the manufacture of railway vehicles and their parts. The required provisions for this process are laid down in the standards series EN ISO 3834. The basis of these provisions is the basic technical welding standards in respect of the special requirements for the construction of r
44、ailway vehicles. This European Standard is aimed at defining the terms of enforcement applicable to European Standards; it is not construed as a substitute to these standards. This European Standard can also be used by internal and external parties, including certification bodies, to assess the orga
45、nisations ability to meet customer, regulatory and the organisations own requirements. DIN EN 15085-3:2010-01 EN 15085-3:2007 (E) 7 1 Scope This series of standards applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their parts. This part of the serie
46、s specifies design and classification rules applicable to the manufacture and maintenance of railway vehicles and their parts. Upon agreement with the customer, drawings issued prior to this European Standard may be subject to the provisions of this European Standard. This European Standard does not
