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 reality by applying similar environmental conditions. The combination of temperature, humidity, and vibration occurs especially in the fields of motor and rail transit.
