SIST HD 22.8 S2:1998/A1:1999

EN 50306-4 specifies requirements for, and constructions and dimensions of, multicore and multipair cables rated voltage Uo/U: 300/500 V, of the following types:
- unscreened, sheathed for either exposed or protected wiring, 0,5 mm2 to 2,5 mm2, number of cores from 2 to 48;
- screened, sheathed for either exposed or protected wiring, 0,5 mm2 to 2,5 mm2, number of cores from 2 to 8;
- unscreened, sheathed for either exposed or protected wiring, 0,5 mm2 to 1,5 mm2, number of screened pairs of c...view more

This standard specifies special test methods applicable to cables, and their constituent insulating and sheathing materials, for use in railway rolling stock.  Such cables are specified in the various parts of EN 50264, EN 50306 and EN 50382.

EN 50306-2 specifies requirements for, and constructions and dimensions of, single core cables, rated voltage Uo / U= 300 /300 V, of the following type:  Unscreened, 0,5 mm2 to 2,5 mm2 single core

EN 50306 1 specifies the general requirements applicable to the cables given EN 50306 2, EN 50306 3 and EN 50306 4. It includes the detailed requirements for S2 sheathing materials and other components called up in the separate Parts. In particular EN 50306 1 specifies those requirements relating to fire safety which enable the cables to satisfy Hazard Level3 of EN 45545-1 and -2.

EN 50306-3 specifies requirements for, and constructions and dimensions of, multicore cables, rated voltage Uo/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.

This part of EN 61238 applies to compression and mechanical connectors for power cables for rated voltages above 1 kV (Um = 1,2 kV) up to 36 kV (Um = 42 kV), for example buried cables or cables installed in buildings, having
a) conductors complying with EN 60228 having nominal cross-sectional areas between 2,5 mm2 and 1 200 mm2 for copper and between 16 mm2 and 1 200 mm2 for aluminium, excluding Milliken conductors;
b) a maximum continuous conductor temperature not exceeding 90 °C.
