BS 7846:2015 specifies requirements for construction and performance of thermosetting insulated, armoured, fire-resistant cables of rated voltage 600/1 000 V having low emission of smoke and corrosive gases when affected by fire.This British Standard is applicable to cables for use in fixed installations in industrial areas, buildings or similar applications, where maintenance of power supply during a fire is required for a defined period of time.This British Standard specifies requirements for the following types of cables:wire armoured and oversheathed cables with two-, three-, four- or five-cores, and with stranded copper conductor;multicore auxiliary cables, wire armoured and oversheathed, with stranded copper conductor.This British Standard specifies four categories of cables based on their performance in tests which assess separately resistance to fire, resistance to fire with water spray and resistance to fire with mechanical shock (Category F2) and which assess resistance to fire with direct mechanical impact and water jet in combination (Categories F30, F60 and F120).This British Standard is applicable to cables that are designed for a maximum sustained conductor temperature of 90 °C and for a maximum short-circuit conductor temperature of 250 °C (for a maximum of 5 s).NOTE 1 Limitation on the temperature of the cables might be imposed in situations where they may be touched or where they could touch other materials.NOTE 2 Annex A gives the guide to use, Annex B gives armour wire tests, Annex C gives compatibility test, Annex D gives abrasion test, Annex E gives insulation resistance constant test on oversheath, Annex F gives resistance of conductor and armour, Annex G gives gross cross-sectional area of armour, Annex H gives a test for shrinkage of oversheath, Annex I gives the fire resistance test for category F2 - additional provisions for cables with a diameter over 20 mm, and Annex J gives notes on type tests.Cross References:BS 6387BS 7655-1.2BS 7655-1.3BS 7655-6.1BS 7671BS 8491BS EN 10244-2:2009BS EN 50363-5BS EN 50395BS EN 50396BS EN 60228BS EN 60229BS EN 60332-1-2:2004BS EN 60332-3-24:2009BS EN 60754-1BS EN 60811-501BS EN 60811-502BS EN 61034-2BS EN 62230IEC 60050-461BS 5099BS 7846:2009BS 8512BS 8519:2010BS 8573:2012BS EN 50265-2-1BS EN 50266-2-4BS EN 50356BS EN 50393BS EN 60079-14BS EN 61914BS EN 62275BS EN 62444IEC 60183Replaces BS 7846:2009 which remains current.All current amendments available at time of purchase are included with the purchase of this document.
