EN 50125-1:1999

EN 50125-1:1999 is a standard published by CLC. Its full title is "Railway applications - Environmental conditions for equipment - Part 1: Equipment on board rolling stock". This standard covers: This standard intends to define environmental conditions within Europe (it can also be applied elsewhere by agreement). The scope of this standard covers the definitions and ranges of 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, for complete rolling stock and all on-board equipment (mechanical, electromechanical, electrical, electronic). In particular the standard defines interface conditions between the vehicle and its environment. The defined environmental conditions are considered as normal in service. Acceptable deviations are defined in the relevant clauses dealing with the environmental parameters, together with any mitigation in operation that may be required. Microclimates surrounding components may be defined by relevant product standards or by special requirements. Passenger effects on the equipment and equipment effects on the passengers are not considered in this standard. The standar does not apply to cranes, mining vehicle, cable cars. The standard also does not apply to natural disaster (earthquakes).
