Flame test: the test flame shall be applied and removed for each 15 seconds respectively
to repeat the cycle 5 times. Overload flame retardant: power (AC) corresponding to 2, 4,
8, 16 and 32 times the power rating shall be applied for each 1 minute until disconnection
occurs. However the applied voltage shall not exceed the value of 4 times of the
maximum operating voltage
