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)
High temperature : +70℃ Low temperature : -30℃ Changeover time: <30secends Duration : 1 hour Cycle : 5
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。 |
