    Fire resistant cables VS Flame retardant cables

    An important distinction exists between fire resistant cables and flame retardant cables, even though both of them are subjected to various fire performance tests in order to earn their respective classification. In brief, flame retardant cables are designed to resist the spread of fire into a new area. Fire resistant or fire rated cables are designed to maintain circuit integrity and continue to work for a specified period of time under defined conditions. 

    Our fire performance cables are usually manufactured according to the standards as follows:

    Fire resistant and flame retardant standards:

    BS7629-1, BS8592, BS EN 50200 PH30 / PH60 / PH120, BS7846 and BS6387 CWZ,BS8491,BS8434-2, IEC 60331-21, IEC 60331-23, IEC 60331-25, IEC 60331-1, IEC 60331-2, IEC 60331-3, IEC 60332-1-2, IEC 60332-3-22, IEC 60332-3-23, IEC 60332-3-24, BS EN 60332-3-22, BS EN 60332-3-23, BS EN 60332-3-24
