Gives requirements and test methods for the construction and performance of non-armoured, single core non-sheathed cables which: a) have a thermosetting insulation of rated voltage 450/750 V; b) provide resistance to fire (circuit integrity), including mechanical shock, as measured by performance in a standard test; c) emit limited amounts of smoke and corrosive gases when burned as measured by a standard test; d) are flame retardant; and e) are primarily, but not exclusively, intended for use inside metal enclosures such as steel conduit. inside metal enclosures such as steel conduit.

This British Standard 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 450/750V; 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; and 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. NOTE1 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 5s). NOTE2 AnnexA gives recommendations for the selection, installation and operation of cables. AnnexB gives notes on type tests.
