1 Scope
This European Standard intends to define environmental conditions within Europe.
NOTE 1 It can also be applied elsewhere by agreement.
The scope of this European Standard covers the definitions and ranges of the following
parameters:
Altitude, temperature, humidity, air movement, rain, snow and hail, ice, solar radiation,
lightning, pollution for rolling stock and on-board equipment (mechanical, electromechanical,
electrical, electronic).
In particular, this European Standard defines interface conditions between the vehicle
and its environment. The defined environmental conditions are considered as normal in service.
NOTE 2 Further guidance on severe conditions can be found within prCEN/TR 16251.
Rolling stock or parts of it can also be used outside the specification with reduced
performance.
NOTE 3 In these cases, relevant operating rules could be necessary to ensure the technical compatibility between the rolling stock and environmental conditions.
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 European Standard.
This European Standard does not apply to cranes, mining vehicles, cable cars. This
European Standard also does not apply to natural disaster (e.g. earthquake).
