EUROLAB laboratory provides testing and compliance services within the scope of EN 50125-1 standard. This part of the EN 50125 standard covers definitions and ranges of pollution parameters for altitude, temperature, humidity, air movement, rain, snow and hail, ice, solar radiation, lightning, railcars and on-board equipment (mechanical, electromechanical, electrical, electronic).
It aims to describe environmental conditions within Europe. It can be applied elsewhere by agreement. In particular, this European Standard defines the interface conditions between the vehicle and its environment. The defined environmental conditions are considered normal in service. Further guidance on severe conditions can be found in prCEN/TR 16251.
Rolling stock or parts thereof may also be used outside specification with poor performance. In these cases, relevant operating rules may be necessary to ensure technical compatibility between rolling stock and environmental conditions.
The microclimates surrounding the components can be defined according to the relevant product standards or special requirements. Passenger effects on equipment and equipment effects on passengers are not considered in this European Standard.
This European Standard does not apply to cranes, mining vehicles, ropeways. This European Standard also does not apply to natural disasters (eg earthquake).
Temperatures are informative as maximum and minimum values inside a vehicle and should be considered in the design of equipment inside the vehicle. Where different operating temperatures are taken into account depending on local information or operating temperature ranges are limited to heating or cooling systems, these will be agreed and specified in the specification.
A reference temperature of 25°C is considered the permanent temperature at which the effects on material aging are equivalent to the climate temperature over the lifetime. When specified in product or equipment standards, special requirements apply.
Where certain system characteristics or performances are disproportionately affected by temperature extremes, it is permissible for such equipment to be devalued and installed in a controlled climate environment. The temperature range must be defined in the specification. The temperatures inside the vehicle are values measured in the free air emanating from the heat emitting elements.
It will be taken into account that the outdoor air temperature may exceed the outdoor outdoor temperature in special places such as near ballast or on the roof. In this case, the temperature level to be considered will be specified in the specification.
