In the course of the experiment, the test sample should be electrified.
For heat dissipation samples, the relevant specifications may require the sample to be opened before or after the reduction of air pressure and functional tests and / or measurements, and sufficient time to achieve thermal stability.
When the pressure returns to normal pressure. In accordance with the requirements of the relevant specifications, the rate of change of air pressure shall not exceed 10kpa / min.
If not specified in the relevant specifications, the test shall be carried out at standard atmospheric pressure for 1 to 2 hours. In accordance with the requirements of the relevant specifications, visual testing and other testing.
