ACL FIRE GUARD Cable ACL FIRE GUARD Cable prevents spreading of flame prevents spreading of flame even if it catches fire. The even if it catches fire. The above test is used to above test is used to demonstrate the cables ability demonstrate the cables ability to limit flame spread. The flame to limit flame spread. The flame spread is measured as the spread is measured as the extent of damage of the cable extent of damage of the cable sample, subject to direct fire sample, subject to direct fire under strict conditions.under strict conditions.
