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.
