Railway applications – Environmental conditions for equipment – Part 1: Equipment on board rolling stock
|Publication Date:||1 August 2010|
|ICS Code (Railway rolling stock):||45.060|
This part of IEC 62498 intends to define environmental conditions.
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 standard defines:
- interface conditions between the vehicle and its environment;
- general environmental rules for the equipment of rolling stock, especially for the main subsystems.
In this respect it gives general guidance in order to allow the fairness of bid assessments.
The defined environmental conditions are considered as normal in service; occasionally more severe conditions may be specified.
Microclimates surrounding components may be defined by relevant product standards or by special requirements.
This standard is not intended to apply to cranes, mining vehicles, cable cars.
Passenger effects on the equipment and equipment effects on the passengers are not considered in this standard.
