This part of IEC 60331 specifies the test apparatus to be used for testing cables required to maintain circuit integrity when subject to fire alone where the test condition is based upon a flame with a controlled heat output corresponding to a temperature of at least 750 °C.
It also provides in annex A the method of verification of the burner and control system used for the test.
