BS 6724 cables

TITLE: BS 6724 are Electric cables. Thermosetting insulated, armoured cables with rated voltages of 600/1 000 V and 1 900/3 300 V for fixed installations have low emissions of smoke and corrosive gases when affected by fire.

SCOPE:  BS6724 is a British Standard that 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. BS 6724 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:

• 600/1000 V cables, wire armoured and oversheathed having single-core, two-, three-, four- and five-core stranded copper conductor or 
• 600/1000 V multicore auxiliary cables, wire armoured, and oversheathed, having 7, 12, 19, 27 and 37 core stranded copper conductors;
• 1 900/3300 V cables, wire armoured and oversheathed, having single-core or three-core stranded copper conductors.

The cables specified in BS6724 standard are designed to have improved fire performance when installed in air and are expected to be used primarily in such locations. The cables are also suitable for direct burial in free-draining soil conditions but not in waterlogged soil or ground subject to flooding.

• Note 1: Recommendations for the selection and operation of cables are given in Annex A. 
• Note 2: Recommendations for the installation of cables are given in annex B. 
• Note 3: Information to be provided with the enquiry or order is given in annex C.
