Gives test procedure and the performance requirement, including a recommended flame application time, for electric data cables that are needed to maintain circuit integrity when subjected to fire under specified conditions. Describes the continuity checking arrangements, electrical testing procedure, sample preparation, method of burning the cables and gives requirements for evaluating test results. Covers electric data cables which do not have a rated voltage and are used for extra low voltage circuits.
