After the test sample has undergone a severe low temperature test, the shape of some test samples will change accordingly. In fact, it is not difficult to recover the sample! We can achieve this by the following methods:
1. Test samples should be recovered under standard atmospheric conditions until they are thawed.
Second, in order to remove water droplets, the sample can be shaken with a hand shake, or air blown at room temperature for a short period of time.
3. If required by the relevant specifications, the test sample shall be energized or loaded during the recovery period and its performance shall be continuously measured.
4. When the standard atmospheric conditions are not suitable for the test sample, the relevant specifications may specify other recovery conditions.
5. When the test sample is recovered under standard atmospheric conditions, the recovery time should be sufficient to achieve temperature stability for at least one hour. When several samples are tested at the same time, and the recovery time of one hour is sufficient, the longest recovery time is obtained. For two hours, all measurements must be completed before the end of this time.
