This document describes the basic terms and definitions as well as general procedures for strength assessment of rail vehicle structures that are manufactured, operated and maintained according to standards valid for rail system applications. The assessment procedure is restricted to ferrous materials and aluminium. This document does not define design load cases. This document is not applicable for corrosive conditions or elevated temperature operation in the creep range. This document is applicable to all kinds of rail vehicles.

This document is applicable to relay valves designated to control the brake cylinder pressure of compressed air brakes fitted to railway vehicles, in association with an air brake distributor valve or other control device. It covers one stage relay valves and relay valves adjusting the brake cylinder pressure in response to a change in vehicle speed or load that is either continuously variable or in two or more stages, i.e. empty – loaded. Relay valves operating with other pressures, in particular the brake pipe pressure, are not included. This document specifies the requirements for the design, manufacture and testing of relay valves.

This European Standard specifies a procedure for fatigue strength assessment of rail vehicle structures based on cumulative damage. It is part of a series of standards that specifies procedures for strength assessments of structures of rail vehicles that are manufactured, operated and maintained according to standards valid for railway applications. This document is applicable for variable amplitude load data with total number of cycles higher than 10000 cycles. An endurance limit approach is outside the scope of this European Standard. The assessment procedure of the series is restricted to ferrous materials and aluminium. This document series does not define design load cases. This document series is not applicable for corrosive conditions or elevated temperature operation in the creep range. This series of standards is applicable to all kinds of rail vehicles, however it does not define in which cases a fatigue strength assessment using cumulative damage is to be applied.

This document defines terms in the field of welding on railway vehicles and associated components. This document is applicable 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 4063.
