DESCRIPTION

CSN EN 50306-3 ed. 2

CSN EN 50306-3 ed. 2 This document specifies requirements for, and constructions and dimensions of, multicore cables, rated voltage U0/ U = 300/500 V, of the following type: Screened (0,5 mm2 to 2,5 mm2, number of cores from 1 to 8). All cables have stranded tinned copper conductors, and thin wall thickness, halogen-free, insulation and sheath. They are for use in railway rolling stock as fixed wiring or wiring where limited flexing in operation is encountered. These cables are rated for occasional thermal stresses causing ageing equivalent to continuous operational life at a temperature of 90 °C. For standard cables, this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 110 °C/20 000 h temperature index. If the customer were to require lifetime predictions this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. Under fire conditions, the cables exhibit special performance characteristics in respect of maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases. These requirements are specified to permit the cables to satisfy Hazard Level 3 of EN 45545-1 and EN 45545-2. EN 50306-2:2020 is expected to be used in conjunction with EN 50360-1:2020, General requirements and EN 50306-2:2020, Single core cables.
