    Abstract - (Show below) - (Hide below)

    Defines requirements for constructing and establishes test methods for armoured cables having thermosetting insulation of rated voltages 600/1000 V and 1900/3300 V for production of lower levels of smoke and corrosive products when exposed to fire comparable with cables conforming to BS 5467.
