BS 8592:2016 specifies requirements and test methods for the
construction and performance of non-armoured, single core non-sheathed cables
which:have a thermosetting insulation of rated voltage 450/750 V;provide resistance to fire (circuit integrity), including mechanical shock, as
measured by performance in a standard test;emit limited amounts of smoke and corrosive gases when burned as
measured by a standard test;are flame retardant; andare primarily, but not exclusively, intended for use inside metal enclosures
such as steel conduit.This British Standard is applicable to cables for use in fixed installations in
industrial areas, buildings and similar applications, where maintenance of power
supply during a fire is required for a defined period of time.NOTE 1 Attention is drawn to the fact that the ability of a given cable to meet the
test in this standard refers only to the test conditions stated, and the level of
performance achieved in a particular installation can be influenced by actual
installation conditions.The insulation and other components are suitable to permit operation of the
cables at 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 Annex A gives recommendations for the selection, installation and
operation of cables. Annex B gives notes on type tests.Cross References:BS EN 50363-5BS EN 50395BS EN 50396BS EN 60228BS EN 60332-1-2:2004+A1:2015BS EN 60754-1BS EN 60811-502BS EN 61034-2BS EN 62230IEC 60050-461IEC 60331-3BS 5266BS 5839BS 7671BS 8519BS EN 50565-1All current amendments available at time of purchase are included with the purchase of this document.
