32、085-3:2007 (E) 6 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 provisions is the basic technical welding standards in respect of the spec
33、ial requirements for the construction of railway 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, includin
34、g certification bodies, to assess the organisations ability to meet customer, regulatory and the organisations own requirements. BS EN 15085-3:2007EN 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 an
35、d their parts. This part of the series 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 Stan
36、dard. This European Standard does not define parameters for the dimensioning (refer to other standards e.g. on fatigue testing). 2 Normative references The following referenced documents are indispensable for the application of this document.
