DS DSEN 50525-3-41 2011-JUN-24 Electrc cables - Low voltage energy cables of rated voltages up to and ncludng 450750 V U0U - Part 3-41 Cables wth specal fre performance - Sngle core non-sheathed cables wth halogen-free crosslnked nsulaton and low emsson of smoke
EN 50525-3-41 applies to non-sheathed single core cables insulated with halogen-free crosslinked compound and having low emission of smoke and corrosive gases when exposed to fire.NOTE 1 Low emission of smoke is checked in accordance with EN 61034-2. Low emission of corrosive gases is checked as part of the check for absence of halogens (see Annex B of EN 50525-1).The cables are of rated voltages U0/U up to and including 450/750 V.NOTE 2 Cables rated 450/750 V may be used at 600/1 000 V when this cable is used in fixed installations with mechanical protection, within switchgear and control gear - see HD 516.The cables are intended for fixed wiring applications.The maximum conductor operating temperature for each of the cables in this standard is 90 °C.NOTE 3 HD 516 contains extensive guidance on the safe use of cables in this standard.This EN 50525-3-41 should be read in conjunction with EN 50525-1, which specifies general requirements.
