Electric cables. Low voltage energy cables of rated voltages up to and including 450/750 V (U0/U) -- Cables with special fire performance. Single core non-sheathed cables with halogen-free crosslinked insulation, and low emission of smoke
ENÂ 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 450/750Â V.
NOTEÂ 2 Cables rated 450/750Â V may be used at 600/1Â 000Â 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.
NOTEÂ 3 HD 516 contains extensive guidance on the safe use of cables in this standard.
This ENÂ 50525-3-41 should be read in conjunction with ENÂ 50525-1, which specifies general requirements.
