EN 15085-2:2007 (E) 4 Introduction Welding is a special process in the manufacture of railway vehicles and their parts. The required provisions for this process are laid down in the stand
22、ards series EN ISO 3834. The basis of these provisions are the basic technical welding standards in respect of the special requirements for the construction of railway vehicles. This standard is aimed at defining the terms of enforcement applicable to European Standards, it should not be construed a
23、s a substitute to these standards. This standard can also be used by internal and external parties, including certification bodies, to assess the organisations ability to meet customer, regulatory and the organisations own requirements. EN 15085-2:2007 (E) 5 1 Scope This series of standards applies
24、to welding of metallic materials in the manufacture and maintenance of railway vehicles and their parts. This part of the series defines the certification levels as well as the requirements for welding manufacturers and describes the procedure for the recognition of welding manufacturers. 2 Normativ

34、elding manufacturers The quality requirements for welding manufacturers, which carry out welding work on rail vehicles, components and sub-assemblies, are specified by the standard series EN ISO 3834. Dependant on the certification level, the requirements of EN ISO 3834-2, EN ISO 3834-3 or EN ISO 38
35、34-4 shall be fulfilled in principle (see Annex A). Welding manufacturers, which carry out welding work on railway vehicles, components and sub-assemblies, shall be certified according to this standard, if specified. Compliance with the requirements shall be checked and certified by a recognised man
36、ufacturer certification body (see Clause 6). Four certification levels (CL) are laid down for the certification of welding manufacturers (Level 1 to Level 4). Level 1 to Level 3 depends on the weld performance classes CP A to CP D of the welded joints specified in EN 15085-3:2007, Table 2. Table 1 c
37、ontains a description of the certification level and the allocation in the weld performance classes. The required certification level depends on the following two items: 1) Table 1; 2) safety relevance of the components or sub-assemblies where the welded part is integral (see list beneath Table 1).
38、1) For railway applications, only EN ISO 15614-1, EN ISO 15614-2, prEN ISO 15614-3, EN ISO 15614-4, EN ISO 15614-7, EN ISO 15614-11, EN ISO 15614-12 and EN ISO 15614-13 are relevant. EN 15085-2:2007 (E) 7 Table 1 Certification level Description Certification leve (CL) This level applies to welding m
39、anufacturers which manufacture welded railway vehicles or their welded parts with welded joints classified in weld performance classes CP A to CP D. Certification level CL 2 to CL 4 is included. CL 1 This level applies to welding manufacturers which manufacture welded parts of railway vehicles with
40、welded joints classified in weld performance classes CP C2 to CP D. Welded joints classified in weld performance class CP C1 are included if these welds are checked according to weld inspection class CT 1 according to EN 15085-5:2007, Table 1. Certification level CL 4 is only included according to w
41、elded joints of certification level CL 2 or CL 3. CL 2 This level applies to welding manufacturers which manufacture welded parts of railway vehicles with welded joints classified in weld performance class CP D. CL 3 This level applies to manufacturers which do not weld but design railway vehicles a
42、nd parts of rail vehicles or buy and assemble or sell them. Certification not required for welding works of certification level CL 3. CL 4 Because of their safety relevance the following components and sub-assemblies shall be welded by welding manufacturers with a certification level CL 1. bogie fra
43、mes and bolsters; body shell components (e.g. under frames, structures); buffers and draw gear; wheel set components (e.g. wheel set mountings, axle boxes, spring supports); brake equipment (e.g. magnetic track brake, brake rods, brake triangles, brake cylinders, brake cross beams); supporting frame
44、s for heavy components (e.g. traction units, pantographs); welded components for drag transmission from bogie to vehicle; vibration dampers and their link between bogie and vehicle or between vehicles; finishing welding of castings within components indicated above; external fuel tanks. Annex A cont
45、ains information about possible classifications of the certification levels for further components and sub-assemblies of railway vehicles. EN 15085-2:2007 (E) 8 According to EN 15085-3:2007, certification level CL 1 to CL 3 necessary for the product shall be clearly indicated in the engineering docu
46、mentation (e.g. on the drawings). If required by the customer, the certification level shall be agreed with him respecting the national safety authority. 5 Quality requirements for the welding manufacturer 5.1 Staff requirements 5.1.1 Welders and welding operators The welding manufacturer shall have
47、 welders and welding operators with qualification in accordance with EN 287-1, or EN ISO 9606-2 or with EN 1418. Qualification shall cover each the welding processes, material groups, joint types and welding positions needed for production. Such qualification should be carried out by either: accredi
48、ted examining body, responsible welding coordinator of the manufacturer, recognised by the manufacturer certification body as specified in 5.1.2. If fillet welds are done in production a fillet weld test piece is necessary. 5.1.2 Welding coordination The welding manufacturer shall have suitably expe
49、rienced welding coordinators with the relevant technical knowledge according to EN ISO 14731. The manufacturer shall clearly prove to the manufacturer certification body that the technical knowledge of the welding coordinator(s) is at the required level. Tasks and areas of competence of welding coordinators are given in Annex B. For the purpose of this standard, three levels of welding coordinators are distinguished: Welding coordinators with comprehensive technical knowledge (Level A) Personnel with experience
