Fire Testing
11. Circuit (insulation) integrity in accordance with NBN C 30-004 (cat. F3)
NB N C 32 004 – Fire Resistance of electric cables. Classification and test method.
The cable is stressed by the flame at 900°C with mechanical shocks every 30 seconds for a duration
of 3 hours. The cable is deemed to pass the test if the current leakage does not exceed 1 amp per
conductor. The test must be passed by 4 successive samples.
