Share the three-step operation process of the ventilating cold and heat shock test chamber

Product name: Ventilation type cold and heat shock test chamber

Manufacturer: Dongguan Huanyi Instrument Technology Co., Ltd.

What are the specific operating procedures of the ventilating thermal shock test chamber? Generally speaking, it can be divided into three steps. The following Dongguan Huanyi Instrument will share with you the specific operating procedures of the ventilating thermal shock test chamber:

A. Put the sample under normal test atmospheric conditions until its temperature becomes stable.

B. Comparing with the standard requirements, put the samples that meet the requirements directly into the ventilating thermal shock test chamber.

C. Start to experiment:

1. Put the test sample into the ventilating thermal shock test chamber according to the standard requirements, and at the same time raise the temperature in the test chamber to the temperature, and then keep it for a period of time to stabilize the temperature of the sample.

2. After the test in the high temperature stage is over, switch the sample to a low temperature test chamber at -55°C within five minutes, and keep it for 1 hour or longer until the temperature of the sample reaches a stable temperature.

3. After the test in the low temperature stage is over, switch the sample to a high temperature test chamber at 70°C within five minutes, and keep it for 1 hour or longer until the temperature of the sample reaches a stable level.

4. Repeat the above test method three times to complete the cycle. Depending on the size of the sample and the space, there may be a slight error in the time.

5. After the sample is taken out from the test chamber, it needs to be restored for a certain period of time under normal test atmospheric conditions until the temperature of the sample reaches a stable level.

6. After comparing the degree of damage in the standard to evaluate the test results.
