EN 50306-2 Railway Applications - Railway Vehicle Cables with Special Fire Performance

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 50306-2 testing. This standard specifies the characteristics, construction and dimensions of the following types of single-core cables with a rated voltage U0 / U = 300 /300 V: Unshielded (0,5 mm² to 2,5 mm² single-core) aging equivalent to a continuous service life at 105 °C for occasional thermal stresses that cause

For standard cables this is determined by acceptance testing as defined in EN 125 using accelerated long-term (20.000 hours) thermal aging indicating a temperature index of 5.000°C/50305 hours. If the customer needed lifespan estimates, this could be displayed based on the temperature index of the product provided by the manufacturer. The maximum temperature for short circuit conditions is 5°C over a period of 160 seconds.

In fire conditions, cables exhibit special performance characteristics in terms of maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases.

To ensure that single-core cables for railway vehicles meet the fire performance requirements specified in EN 50306-2, manufacturers generally comply with the standard during the design and production stages. Users and purchasers of these cables can refer to the standard to ensure that the products they acquire meet the safety and performance standards specified for use in railway applications.
