High and low temperature test to how long it depends on the samples to be tested in which industry, the use of the environment can almost determine the temperature required for testing. Then understand the industry needs to meet the standards, which will provide samples in the high-temperature environment, low-temperature environment, the respective storage time, plus the number of high and low temperature cycle and high and low temperature test chamber time required to raise and lower the temperature, you can almost calculate a high and low temperature test the total length of time required is how much.

If you need a long time and uninterrupted high and low temperature test users, in the selection of high and low temperature test chamber is best to choose the quality of the equipment is guaranteed to ensure that the process of testing will not be due to equipment failure and lead to experiments are forced to stop.

1, high temperature is generally 48 hours, low temperature 24 hours.

2, high and low temperature test is used to determine the adaptability of the product in the high temperature climate environment conditions of storage, transportation, use. The severity of the test depends on the temperature of the high temperature and exposure duration.

3, temperature range: -40 ℃ ~ 150 ℃, temperature difference: ± 0.5 ℃

　　Humidity range: 20～98%RH, humidity difference: ±2.5%RH

　　Warming time: from room temperature to 100 ℃, the time is 30 minutes

　　Cooling down range: from room temperature to -40℃, time is 45 minutes.

　　For the electronics industry, manufacturers widely used in high temperature power aging test, usually to do a few hours or dozens of hours. The main function is to screen components with multiple potential failures. In fact, different industries have different requirements, the length of the actual high and low temperature test is generally done in accordance with the specific needs of customers.
