Quality Information Test Item High Temperature storage storage temperature for a long time. Low Temperature storage Endurance test applying the low storage temperature for a long time. High Temperature Endurance test applying the electric stress Operation (voltage & current) and the high thermal stress for a long time. Low Temperature Endurance test applying the electric stress Operation (voltage & current) and the low thermal stress for a long time. High Temperature / Endurance test applying the electric stress Humidity Operation (voltage & current) and the high thermal with high humidity stress for a long time. Thermal Shock resistance Endurance test applying the electric stress (voltage & current) during a cycle of low and high thermal stress. Vibration test Endurance test applying vibration to simulate transportation and use. Static electricity test Endurance test applying electric static discharge. Note 1: No condensation to be observed. Note 2: Conducted after 4 hours of storage at 25 Note 3: Test performed on product itself, not inside a container.
