(6) IEC (International Electronical Commission)-65 Specification.

(a) IEC (International Electronical Commission)-65 is the standard, parts testing method, machinery and tolls (used in connecting main

power directly and indirectly) Which are used at home and general building. The purpose of the above standard is not to breaking out the

risk which is related to an electric shock, a heating, a fire and the damage of surrounding parts in the case of normal or abnormal operating.

(b) In case temperature is limited by temperature overheating prevention device, fuse or the operation of fuse resistor

One must calculate the temperature of PCB substrate in 2 minute.

ΔT≤110℃ regulated

ΔT=T(The PCB substrate temperature in 2 minute)

-Ta(Ambient temperature)

(c) Graph

As the territory of the deviant line appear by the heat, as the

area is wider, T(The PCB substrate temperature in 2 minute)

is becoming high.
