BS 8592:2016

This British Standard specifies requirements and test methods for the construction and performance of non-armoured, single core non-sheathed cables which:

1. have a thermosetting insulation of rated voltage 450/750 V;

2. provide resistance to fire (circuit integrity), including mechanical shock, as measured by performance in a standard test;

3. emit limited amounts of smoke and corrosive gases when burned as measured by a standard test;

4. are flame retardant; and

5. are 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.

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).
