Railway applications - Environmental conditions for equipment

This document intends to define environmental conditions within Europe. This document does not specify the test requirements for equipment. The scope of this document covers the definitions and ranges of the following parameters: altitude, temperature, pressure, humidity, air movement, rain, snow, hail, ice, lightning, electromagnetic compatibility, solar radiation, pollution, vibrations and shocks, environmental conditions in tunnels. The scope of this document is to define environmental conditions in railway environment in order to cover the design and the use/service of the following: — equipment for rolling stock and on-board equipment (mechanical, electromechanical, electrical, electronic); — fixed electrical installations for traction power supply and equipment essential to operate a railway; — equipment and any portable equipment for signalling and telecommunications systems (including test, measure, monitoring equipment, etc.). The defined environmental conditions, including the values herein specified, are considered as normal and do not concern extreme conditions or natural disasters (e.g earthquake, nuclear radiation). This document does not apply to cranes, mining vehicles, cable cars, escalators, lifts, fire protection, lighting in tunnels and on platforms, ticket machines, ventilation systems, installations in underground mines, suspended cable cars and funicular railways. The effects of vandalism on the equipment are not considered in this document. Microclimates surrounding components and passenger effects on the equipment and equipment effects on the passengers are not considered in this document.
