23、 flexible cables, insulated and sheathed with halogen-free thermoplastic 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 abse

24、nce of halogens (see Annex B of EN 50525-1). The cables are of rated voltages U0/U up to and including 300/500 V. The cables are intended for the connection of domestic appliances to the fixed supply. Circular cables and flat cables are included. The maximum conductor operating temperature for each

25、of the cables in this standard is 70 C. NOTE 2 HD 516 contains extensive guidance on the safe use of cables in this standard. This EN 50525-3-11 should be read in conjunction with EN 50525-1, which specifies general requirements. 2 Normative references The following referenced documents are indispen
