Title Cables of rated voltages up to and including 450/750 V and having thermoplastic insulation - Part 15: Single core cables, insulated with halogen-free thermoplastic compound, for fixed wiring
Project Number 13607
Abstract/Scope This Part 15 details the particular specifications for single-core non-sheathed cables for fixed wiring at rated voltages up to and including 450/750 V, insulated with halogen-free thermoplastic compound and having low emission of smoke and corrosive gases when exposed to fire. 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 (EN 50266-2-4) than Type 1, and have particular suitability for installation in bunches (see also Annex C). The maximum permissible conductor temperature is 70 C. All cables shall comply with the appropriate requirements given in Part 1 of HD 21 and with the particular requirements of this Part 15. NOTE 1 The overall dimensions of cables in HD 21.15 S1 have been calculated in accordance with EN 60719. NOTE 2 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 A).
