EN 50525-3-31 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.<\/p>\n

\n

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).<\/p>\n<\/blockquote>\n

The cables are of rated voltages U0<\/sub>\/U up to and including 450\/750 V.<\/p>\n

\n

NOTE 2 Cables rated 450\/750 V may be used at 600\/1 000 V when this cable is used in fixed installations with mechanical protection, within switchgear and control gear – see HD 516.<\/p>\n<\/blockquote>\n

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 60332-3-24) than Type 1, and have particular suitability for installation in bunches (see also HD 516).<\/p>\n

The cables are intended for fixed wiring applications.<\/p>\n

The maximum conductor operating temperature for each of the cables in this standard is 70 \u00b0C.<\/p>\n

\n

NOTE 3 HD 516 contains extensive guidance on the safe use of cables in this standard.<\/p>\n<\/blockquote>\n

This EN 50525-3-31 should be read in conjunction with EN 50525-1, which specifies general requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"
