Flame Retardant

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
