| Notes |
◆ Case Temp. shall be controlled in range Tcase ≧ Tstress - 2℃
◆ Surrounding air should be maintained to within Ta ≧Tstress - 5℃ during testing
◆ Humidity ≦ 65% R.H.
◆ Airflow shall be minimized because of heat characteristics that differ due to variation in airflow.
◆ The Tcase、Ta、If should be monitored & recorded. Once the test conditions is not match, the test duration timer should stop accumulating. |
