Readers may be puzzled. What are the points we need to be accurate in the constant temperature and humidity test chamber? After all, if you accidentally make a mistake, you may lose all of them. Then Xiaobian will give you some little knowledge!
Below we describe the six elements of the temperature test in the constant temperature and humidity chamber:
1. When the bulk sample is tested, the updraft and downdraft will have temperature and humidity deviations, so we should carefully consider where to place the sample and place it in the center of the laboratory of the temperature test equipment. The samples should not touch and overlap, leaving a little space for the air to circulate smoothly. It should also ensure that the sample can be easily moved and the sample can be easily replaced during the test.
2. Check the presence or absence of volatile substances such as oil and gas in the test area, check for odorless substances, and the test results of such substances should be determined in advance.
3. Observe the temperature condition of the test sample in the test area of ​​the temperature test equipment.
4. In order to keep the temperature in the temperature zone consistent, ensure that the test environment temperature and equipment power supply fluctuations are minimized. The test sample does not generate heat radiation and does not absorb heat to ensure the temperature of the test area is stable.
5. After the end of the temperature test, the sample is quickly removed without any unnecessary stress on the sample, and unexpected results may be obtained, so the sample must be removed after the test sample has cooled to ambient temperature.
6. The test sample should be installed and the thermal conductivity of the support frame should be low to ensure that the test sample and the mounting and support frame are in an adiabatic state.
