Specifies the apparatus, procedures and performance requirements to be used for testing cables required to maintain circuit integrity when subjected to fire under specified conditions.

This Standard specifies the test apparatus, the test procedure and the performance requirements to be used for testing cables of rated voltages up to 0.6/1.0kV, data cables and optical cables which are required to maintain circuit integrity when subject to fire alone. The test condition is based upon a flame with a controlled heat output corresponding to a temperature of a least 750°C.It also covers testing of cables of rated voltages up to 0.6/1.0kV when subject to fire and mechanical shock where the test condition is based upon a flame with a controlled heat output corresponding to a temperature of a nominal 850°C. This method is intended for use when testing cables of greater than 20mm overall diameter.
