Thermal Shock Resistance
Content of Test Endurance test applying the high storage temperature for a long time. Endurance test applying the high storage temperature for a long time. Endurance test applying the electric stress (Voltage & Current) and the thermal stress to the element for a long time. Endurance test applying the electric stress under low temperature for a long time. The module should be allowed to stand at 60℃,90%RH max, for 96hrs under no-load condition excluding the polarizer. Then taking it out and drying it at normal temperature. The sample should be allowed stand the following 10 cycles of operation
