Precautions for the use of temperature test equipment

1. There will be temperature and humidity deviations in the updraft and downdraft when testing large samples, so the location of the samples should be carefully considered. It should be placed in the center of the working space of the temperature test equipment as much as possible. The samples should not touch or overlap with each other, and a certain interval should be left to allow air circulation; it should also ensure that the samples are easy to move during the test, and the samples are easy to replace during the test.

2. Check whether there are volatile substances such as oil and gas in the test area, and check whether there are odorous substances. The test results of such substances must be confirmed in advance.

3. Pay attention to confirm 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, it is necessary to ensure that the fluctuation of the test environment temperature and the power supply of the equipment is as small as possible, to ensure that the test sample does not generate heat radiation and absorb heat so as to ensure that the temperature of the test zone is stable.

5. After the temperature test equipment has finished testing, removing the test sample quickly will cause unnecessary stress to the sample and may result in unexpected results. Therefore, the test sample must be cooled to ambient temperature before removing the sample.

6. The thermal conductivity of the test sample installation and support frame should be low to ensure a thermal insulation state between the test sample and the installation and support frame.

The test content of different products is jointly decided by the test requester, the designer and the test personnel. From the perspective of providing test equipment that is compatible with the test, a technical specification framework of the test equipment is established, and the test equipment supplier can provide the specific specifications of the equipment according to this framework. Every type of test equipment that can simulate a test environment generally has a measurement system, so it is very easy to use off-the-shelf equipment and buy new equipment. Simple test equipment can also be made by yourself, but the cost, reliability of test results, degree of control, and safety factors for continuous operation must be considered.
