3.Reliability Test 可靠性測試

   3.1 LOAD TEST:

     White noise (EIA filter) for 96 hours @ 2.0W input power.

  3.2 HUMIDITY TEST:

     Temperature:     +40±2℃            Relative Humidity:  90%～95%

      Duration :     16 hours

  3.3 HIGH TEMPERATURE TEST:

      High Temperature:      +70℃             Duration:     16 hours

3.4 LOW TEMPERATURE TEST:

Low Temperature:       -30℃             Duration:     16 hours

3.5 DROP TEST:

    Height:      1.5M                     

      Cycle:       10 cycles(Onto the concrete board)


3.6 HEAT SHOCK TEST:

   High temperature :        +70℃

     Low temperature :        -30℃

     Changeover time:       <30secends  

     Duration        :       1 hour

     Cycle          :          5


3.7 TEMPERATURE CYCLE TEST:

   Temperature :          -30℃   +70℃

     Duration    :          45 minutes

     Temperature gradient:    1～3℃/minutes     

     Cycle:                 5

 

All these tests above should be measured after leaving normal temperature for 1hrs.

Sensitivity difference at 1kHz shall be within ±3dB from initial value after test.

以上試驗完畢後必須於常溫狀態下放置1小時再進行檢測。

測試音壓級變化要求1kHz時必須在±3dB以內。
