BS 6724:2016 specifies requirements for the construction andperformance of thermosetting insulated, armoured cables of rated voltagesof 600/1 000 V and 1 900/3 300 V, having low emission of smoke and corrosivegases when affected by fire.
NOTE 1 Other thermosetting insulated, armoured cables for voltages of 600/1 000 Vand 1 900/3 300 V can be found in BS 5467, but these do not have low levels ofemission of smoke and corrosive products under exposure to fire.This British Standard is applicable to cables for use in fixed installations inindustrial areas, buildings or similar applications.This British Standard specifies requirements for the following types of cables:
- 600/1 000 V cables, wire armoured and oversheathed having single-core,two-, three-, four- and five-core stranded copper conductor;
- 600/1 000 V multicore auxiliary cables, wire armoured, and oversheathed,stranded copper conductor; and
- 1 900/3 300 V cables, wire armoured and oversheathed, having single-coreor three-core stranded copper conductor.
This British Standard is applicable to cables that are designed for a maximumsustained conductor temperature of 90 °C and for a maximum short-circuitconductor temperature of 250 °C (for a maximum of 5 s).
NOTE 2 Limitation on the temperature of the cables may be imposed in situationswhere they might be touched or where they could touch other materials.NOTE 3 Annex A gives a guide to the use and installation of cables, Annex B givesarmour wire tests, Annex C gives a compatibility test, Annex D gives an abrasionresistance test, Annex E gives an insulation resistance constant test on oversheath,Annex F gives the resistance of conductor and armour, Annex G gives the grosscross-sectional area of armour, Annex H gives a test for shrinkage of oversheath oncable, Annex I gives guidance on type tests and Annex J gives the standard UnitedKingdom reference codes.Cross References:BS 7655-1.2BS 7655-1.3BS 7655-6.1BS EN 10244-2:2009BS EN 50363-5BS EN 50395BS EN 50396BS EN 60228BS EN 60229 BS EN 60332-1-2:2004+A1:2015BS EN 60332-3-24:2009BS EN 60754-1 BS EN 60811-401BS EN 60811-501BS EN 60811-502BS EN 61034-2 BS EN 62230BS EN ISO 6892-1IEC 60050-461BS 5467BS 7671:2008+A3:2015BS 8512BS 8573:2012BS EN 50262BS EN 50393 BS EN 60079-14BS EN 61914BS EN 62275BS EN 62444IEC 60183Electricity Safety, Quality and Continuity Regulations2002Replaces BS 6724:1997+A3:2008 which remains current
