The combined environmental test refers to the test combining three environmental factors, which are temperature, humidity and vibration. In order to obtain explicit results in a relatively short period of time, we can increase the severity level of the environmental conditions. The evaluation can be carried out in a short period of time by exposing the specimen to a certain range of simulated environmental parameters controlled in the laboratory. Therefore, it is possible to estimate a test result that is close to the reality by applying similar environmental conditions. The combination of temperature, humidity and vibration occurs especially in the fields of motor and rail transit.
The Temperature And Humidity Vibration Test mainly provides temperature and humidity change environment for scientific research and production units such as aerospace, aviation, petroleum, chemical industry, electronics, communication, etc. At the same time, the electric vibration stress can be applied to the test product in the test chamber at a prescribed period , For users to conduct a comprehensive stress screening test of temperature, humidity, and vibration on the whole machine (or parts), electrical appliances, instruments, materials, etc., in order to assess the suitability of the test sample or evaluate the behavior of the test sample. Compared with the effect of a single factor, it can more truly reflect the adaptability of electrical and electronic products to the changes of temperature, humidity and vibration in the environment of transportation and actual use, and expose the defects of products.
