What are the main uses and functions of the thermal shock test chamber?

Correct operation method of thermal shock test chamber

1. Pretreatment: Place the tested sample under normal test atmospheric conditions until the temperature is stable.

2. Initial test: compare the tested sample with the standard requirements, and directly put it into the high and low temperature impact test chamber after meeting the requirements.

3.Test:

1)The test sample should be placed in the test chamber according to the standard requirements, and the temperature in the test chamber should be raised to the specified point and kept for a certain period of time until the test sample reaches a stable temperature, whichever is longer.

2)After the high temperature stage, transfer the test sample to a low temperature test chamber that has been adjusted to -55°C within 5 minutes, and keep it for 1 hour or until the test sample reaches a stable temperature, whichever is longer.

3)After the low temperature stage, transfer the test sample to a high temperature test chamber that has been adjusted to 70°C within 5 minutes, and keep it for 1 hour or until the test sample reaches a stable temperature, whichever is longer.

4)Repeat the above experimental method to complete three cycles. Time may vary slightly depending on sample size and space.

4. Recovery: After the test sample is taken out of the thermal shock test chamber, it should be recovered under normal test atmospheric conditions until the test sample reaches a stable temperature.

5. Final test: evaluate the test results against the damage degree in the standard and other methods.
