12、, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 15085-1:2007 (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 standards series EN ISO 3834. The basis of these provis
13、ions is the basic technical welding standards with respect to the special requirements for the construction of railway vehicles. This standard is aimed at defining the terms of enforcement applicable to European Standards. It will not be construed as a substitute for these standards. This standard c
14、an 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 15085-1:2007 (E) 5 1 Scope This series of standards applies to welding of metallic materials in the manufactur
15、e and maintenance of railway vehicles and their parts. With respect to the railway environment, this series of standards defines the certification and quality requirements for the welding manufacturer to undertake new building and repair work. It then provides an essential link between performance r
16、equirements defined during design, and achieves appropriate quality welds during production and the demonstration of the required quality by inspection. This link is achieved by defining a weld performance class during design, which is based on safety and stress factors relevant to railway operation
17、. Quality levels of imperfections are assigned to weld performance classes to ensure a certain level of performance intended during design. Based on these weld performance classes, certification levels for production as well as inspection and testing and qualifications for welding personnel of the m
18、anufacturer are specified. This standard deals with welding steel and aluminium alloys including castings. NOTE The principle of this standard may also be applied for welding of other parent materials (e.g. Cu, Mg). This part of the series provides general recommendations and definitions for welding
19、 railway vehicles and associated components. Except for specific provisions which are laid down contractually, this standard applies to all assemblies, sub-assemblies or parts welded by any welding process, either manual, partly mechanized, fully mechanized or automatic welding as defined in EN ISO
20、4063. This series of standards does not deal with product qualification. Items of equipment subject to specific regulations are not relevant to the scope of this series of standards, e.g. air reservoirs according to EN 286-3 and EN 286-4. 2 Normative references The following referenced documents are

The
36、manufacturer thus has full freedom to select whichever welding process, consumables and joint preparation they wish to implement. In return, upon customer request, the manufacturer shall demonstrate that they have full control and that the quality level requested by customers will be achieved, in pa
37、rticular through the following: company certification; welder and welding operator qualification; welding process and mock-up qualification. However, customers may contractually restrict the use of certain welding processes. As regards drawings issued prior to the publication of this standard, the p
38、rescriptions laid down herein may be applied. The manufacturer shall inform their customers beforehand. For materials and welding processes outside the scope of this standard, the customer and manufacturer shall agree on new rules or the applicability of existing rules, which achieve the same level
39、of controls as those ensured by this standard. These shall include agreement on quality and certification requirements of the manufacturer, the application of weld performance classes based on stress and safety categories, the definition of imperfection levels to ensure the required levels of perfor
40、mance, and rules for production and inspection to ensure the achievement of quality requirements.
