Amendments This standard differs from DIN 6700-2:2001-
9、05 as follows: a) The content has been updated to reflect the current state of technology and harmonized with European and international standardization. b) The vehicles, components and sub-assemblies are classed into four “certification levels” according to the highest weld performance class CP of
10、the welded joints in the component/sub-assembly, and according to a component list given in clause 4. c) Three levels of welding coordinator are defined. In order to become certified, manufacturers must demonstrate that the technical knowledge of their welding coordinators is at the required level.
11、d) The German term “externe Schweiaufsicht” (external welding coordinator) has been replaced by the term “untervergebene Schweiaufsicht” (subcontracted welding coordinator).

DIN EN 15085-2:2008-01 EN 15085-2:2007 (E) 4 Introduction Welding is a special proce
26、ss 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 are the basic technical welding standards in respect of the special requirements for the construction of railway vehicl
27、es. This standard is aimed at defining the terms of enforcement applicable to European Standards, it should not be construed as 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 mee
28、t customer, regulatory and the organisations own requirements. DIN EN 15085-2:2008-01 EN 15085-2:2007 (E) 5 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 series defines the certificat
29、ion levels as well as the requirements for welding manufacturers and describes the procedure for the recognition of welding manufacturers. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、ts 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 3834-4 shall be fulfilled in principle (see Annex A). Welding manufacturers, which carry out welding work on railway vehicles, com
40、ponents and sub-assemblies, shall be certified according to this standard, if specified. Compliance with the requirements shall be checked and certified by a recognised manufacturer certification body (see Clause 6). Four certification levels (CL) are laid down for the certification of welding manuf
41、acturers (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 contains a description of the certification level and the allocation in the weld performance classes. The required certification
42、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). 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
43、-11, EN ISO 15614-12 and EN ISO 15614-13 are relevant. DIN EN 15085-2:2008-01 EN 15085-2:2007 (E) 7 Table 1 Certification level Description Certification leve (CL) This level applies to welding manufacturers which manufacture welded railway vehicles or their welded parts with welded joints classifie
44、d 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 welded joints classified in weld performance classes CP C2 to CP D. Welded joints classified in weld perf
45、ormance 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 welded joints of certification level CL 2 or CL 3. CL 2 This level applies to welding manufacturers which
46、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 and parts of rail vehicles or buy and assemble or sell them. Certification not required for welding works
47、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 frames and bolsters; body shell components (e.g. under frames, structures); buffers and draw gear; wheel set
48、 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 frames for heavy components (e.g. traction units, pantographs); welded components for drag transmission from b
49、ogie 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 contains information about possible classifications of the certification levels for further components and sub-assemblies of railway vehicles.
