It is divided into 5 parts under the generic title “Railway applications - Railway rolling stock power and control cables having special fire performance”. Part 1 General requirements; Part 2-1 Cables with crosslinked elastomeric insulation Single core cables; Part 2-2 Cables with crosslinked elastomeric insulation Multicore cables; Part 3-1 Cables with crosslinked elastomeric insulation with reduced dimensions Single core cables; Part 3-2 Cables with crosslinked elastomeric insulation with reduced dimensions Multicore cables. Information regarding selection and installation of cables, including current ratings can be found in EN 50355 (Guide to use) and EN 50343 (Rules for installation of cabling). The procedure for selection of cable cross- sectional area, including reduction factors for ambient temperature and installation type, is described in EN 50343. Special test methods referred to in EN 50264 are given in EN 50305. The cables in Part 3-1 may also be used in EN 50264-3-2 to build up multicore sheathed cables. Part 1, General requirements, contains a more extensive introduction to EN 50264, and should be read in conjunction with this Part 3-1. BS EN 50264-3-1:2008 - 5 - EN 50264-3-1:2008 1 Scope EN 50264-3-1 specifies requirements for, and constructions and dimensions of, single core cables of the following 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-free sheath. They are for use in railway rolling stock as fixed wiring, or wiring where limited flexing in operation is encountered. The requirements provide for a continuous conductor temperature not exceeding 90 C and a maximum 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 maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases. EN 50264-3-1 should be read in conjunction with Part 1 “General requirements”. 2 Normative references The following referenced documents are indispensable for the application of this document.
