This European Standard applies to non-sheathed single core cables insulated with halogen-free thermoplastic compound and having low emission of smoke and corrosive gases when exposed to fire. The cables are of rated voltages U0/U up to and including 450/750 V. For cables rated at 450/750 V there are two types, Type 1 and Type 2. Type 2 cables are required to meet a more severe test for resistance to flame propagation than Type 1, and have particular suitability for installation in bunches. The cables are intended for fixed wiring applications. The maximum conductor operating temperature for each of the cables in this standard is 70 °C.
