This standard takes into account environmental conditions within Europe. It can also be applied elsewhere by agreement. The scope of this standard covers the use of on board electrical and electronic equipment for rolling stock, with the following parameters: Altitude, Temperature, Humidity, Air movement, Rain, Snow and Hail, Ice, Solar radiation, Lightning, Pollution, Vibrations and Shocks, Electromagnetic interference environment, Acoustic noise environment, Supply System characteristics. In particular the standard intends to define: -interface conditions between the vehicle and its environment; - general environmental rules for the main sub-systems of a vehicle (cubicles, cabling, large components,...). In this respect it gives general guidance in order to allow the fairness of bids assessments and the process of European projects. The defined environmental conditions are considered as normal in service. Microclimates surrounding components may need special requirements covered by product standard.
