What is BS8436 Standard Cable?
British Standard BS8436 specifies requirements for multicore electric cables with low emissions of smoke and corrosive gases when subjected to fire. The standard covers 2-core, 3-core, and 4-core cables with an uninsulated full-size circuit protective conductor of tinned annealed copper and metallic screening. These cables are specifically designed for use in building voids, partitions and walls where there is a risk of damage or penetration from nails, screw fixings, and similar fasteners.
