EN 50264-1 specifies the general requirements applicable to the cables given in all other parts of EN 50264.It includes the detailed requirements for the insulating and sheathing materials and other components calledup in the separate parts. In particular EN 50264-1 specifies those requirements relating to fire safety.Based on proven experience and reliability over many years these cables are rated for occasional thermalstresses causing ageing equivalent to continuous operational life at a conductor temperature of 90 °C.NOTE This rating is based upon the polymers defined in 3.1 and 3.2. Before these polymers had gained widespread acceptance in thecable industry, ageing performance had been assessed via long-term thermal endurance testing and had been extrapolated to 20 000 husing techniques equivalent to those in EN 60216 (series). Subsequent experience in service has demonstrated that the predictedperformance levels were correct. Where extrapolated data is used to predict lifetime in service it should be confirmed with the cablemanufacturer, and should be on the basis of a failure mode appropriate to the type of material or cable.The maximum conductor temperature for short circuit conditions is 200 °C based on a duration of 5 s.This Part 1 should be read in conjunction with the other parts of EN 50264.
EN 50264-2-1 specifies requirements for, and constructions and dimensions of, single core cables of thefollowing types and voltage ratings:• 0,6/1 kV unscreened, unsheathed (1 mm² to 400 mm²);• 1,8/3 kV unscreened, unsheathed (1,5 mm² to 400 mm²);• 1,8/3 kV unscreened, sheathed (1,5 mm² to 400 mm²);• 3,6/6 kV unscreened, sheathed (2,5 mm² to 400 mm²).All cables have class 5 tinned copper conductors to EN 60228, halogen-free insulation and halogen-freesheath. They are for use in railway rolling stock as fixed wiring, or wiring where limited flexing in operation isencountered. The requirements provide for a continuous conductor temperature not exceeding 90 °C and amaximum temperature for short circuit conditions of 200 °C based on a duration of 5 s.Under fire conditions the cables exhibit special performance characteristics in respect of maximumpermissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases.EN 50264-2-1 should be read in conjunction with Part 1 “General requirements”.
EN 50264-2-2 specifies requirements for, and constructions and dimensions of, multicore cables of thefollowing types and voltage ratings:• 300/500 V screened or unscreened (1 mm², 1,5 mm² and 2,5 mm², number of cores from 2 to 40);• 0,6/1 kV screened or unscreened (1,5 mm² to 50 mm², 2, 3 and 4 cores).NOTE Not all conductor sizes or number of cores are specified for every type.All cables have class 5 tinned copper conductors to EN 60228, halogen-free insulation and halogen-freesheath.
