Some factors that will affect the progress of the high and low temperature test chamber
The severity of the high and low temperature test chamber when performing high and low temperature tests depends on the test temperature level and the duration of the test. The relevant standards should be selected from the following values:
Temperature: The test temperature should preferably be selected from the following values: -65, -55, -40, -25, -10, -5, + 5 ° C.
The allowable deviation range of test temperature is ± 3 ℃.
Duration: After the temperature of the test sample has stabilized, if a low temperature test is required for a certain period of time, the duration should be preferentially selected from the following values: 2, 16, 72, 96h. Whether it can work normally at low temperature, the test time is limited to the temperature of the test sample to stabilize; but in any case, the duration should not be less than 30min.
When this standard is used as the relevant test related to low temperature durability or reliability, the relevant standard requirements for the duration of the test are required.
