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).
