Fire Resistant Cable Standard

Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services.

Fire resistant cable standard.

Thermosetting insulated armoured fire resistant cables of rated voltage 600 1000 v having low emission of smoke and corrosive gases when affected by fire. Standard fire resistance is recommended for general use. These cables are designed to continue to operate for a period of time in a fire situation. Commonly needed fire resistant cable had to meet the requirements of two tests in two british standards.
