BS 8592:2016

BS 8592:2016 specifies requirements and test methods for theconstruction and performance of non-armoured, single core non-sheathed cableswhich:

• have a thermosetting insulation of rated voltage 450/750 V;
• provide resistance to fire (circuit integrity), including mechanical shock, asmeasured by performance in a standard test;
• emit limited amounts of smoke and corrosive gases when burned asmeasured by a standard test;
• are flame retardant; and
• are primarily, but not exclusively, intended for use inside metal enclosuressuch as steel conduit.

This British Standard is applicable to cables for use in fixed installations inindustrial areas, buildings and similar applications, where maintenance of powersupply 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 thetest in this standard refers only to the test conditions stated, and the level ofperformance achieved in a particular installation can be influenced by actualinstallation conditions.The insulation and other components are suitable to permit operation of thecables at a maximum sustained conductor temperature of 90 °C and for amaximum short-circuit conductor temperature of 250 °C (for a maximum of 5 s).NOTE 2 Annex A gives recommendations for the selection, installation andoperation 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 61034-2 BS EN 62230IEC 60050-461IEC 60331-3BS 5266BS 5839 BS 7671BS 8519BS EN 50565-1
