USE OF ELECTRONIC COMPONENTS IN SIGNALLING. NON-ELECTRICAL ENVIRONMENT IN THE CASE OF ELECTRONIC SIGNALLING SYSTEMS

The report describes the non-electrical environment which needs to be taken into account when planning railway safety installations containing electronic components. Explanations cover the following effects: air pressure variations, chemical effects, water, humidity, temperature effects, mechanical stresses, and a combination of environmental effects in relation to the four ways in which safety installations may be accommodated: closed rooms, capsulated outdoor installations, lineside equipment, tractive units and other vehicles. The tabulation of the values which are typical of the parameters of the non-electrical environment completes the report.
