A. Storage Environment


       Test temperature, humidity, and air pressure as follows if not specified:

       1. The temperature is-40℃ ~+85℃

       2. The relative humidity is 45%-85%

       3. The air pressure is 86kpa-106kpa

       Result: Electrical and mechanical properties are normal.


       B. High and low temperature test


       Circulate 5 times between 70℃ and -40℃, and then check the appearance quality under normal conditions for 1-2H.

         Result:  The dimensions shall meet the requirements and meet the mechanical and electrical properties.


       C. Steady damp heat test


      The relative humidity is 95 ± 3%, test temperature: 40℃. After 2 hours' test, the electrical performance of the test product shall be measured within 5 minutes after it is taken out, and the appearance quality of the test product shall be checked under normal conditions for 1-2 hours.


       Result:  The dimensions shall meet the mechanical and electrical properties requirements.




    D. Vibration Test


     The vibration frequency range is 10-55HZ, the displacement amplitude is 0.35MM, and the acceleration amplitude is:

     50.0M/S, frequency sweeping cycles: 30 times

     Result:  The appearance, size and electrical and mechanical properties are normal.


       F. Drop Test

       At the height of 1 meter, free fall for three times according to the axis directions perpendicular to each other.


        Result:  The appearance, size and electrical and mechanical properties are normal.
