BS 6724:2016 specifies requirements for the construction and performance of thermosetting insulated, armoured cables of rated voltages of 600/1 000 V and 1 900/3 300 V, having low emission of smoke and corrosive gases when affected by fire.

NOTE 1 Other thermosetting insulated, armoured cables for voltages of 600/1 000 V and 1 900/3 300 V can be found in BS 5467, but these do not have low levels of emission of smoke and corrosive products under exposure to fire.

This British Standard is applicable to cables for use in fixed installations in industrial 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-core or three-core stranded copper conductor.

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 2 Limitation on the temperature of the cables may be imposed in situations where 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 gives armour wire tests, Annex C gives a compatibility test, Annex D gives an abrasion resistance test, Annex E gives an insulation resistance constant test on oversheath, Annex F gives the resistance of conductor and armour, Annex G gives the gross cross-sectional area of armour, Annex H gives a test for shrinkage of oversheath on cable, Annex I gives guidance on type tests and Annex J gives the standard United Kingdom reference codes.
