Gives the test procedure and performance requirement which includes a recommended flame application time, for cables of rated voltages up to and including 0,6/1,0 kV needed to maintain circuit integrity when subjected to fire under specified conditions. Describes the means of continuity checking arrangements, electrical testing procedure, method of burning and gives requirements for evaluating test results. Meant to cover low voltage power cables and control cables with rated voltage.
