scope:

This standard intends to define environmental conditions within Europe.

NOTE can also be applied elsewhere by agreement.

The scope of this standard covers the use of on board electrical,electromechanical and electronic equipment for rolling stock, for 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 standards defines:

- interface conditions between the vehicle and its environment.

- general environmental rules for the equipment of rolling stock, especially for the main sub-systems (level 3-defined by R009-003 of a vehicle (cubicles, cabling, large components, etc.)

In this respect it gives general guidance in order to allow the fairness of bid assessemnts in the process of European Projects.

The defined environmental conditions are considered as normal in service; occasionally more severe conditions may be specified.

Microclimates surrounding componenets may be defined by relevant product standards or by special requirments.

This standard is not intended to apply to cranes, mining vehicles, cable cars.

Passenger effects on the equipment and equipment effect on the passengers are not considered in this standard.
