How long the high and low temperature test takes mainly depends on which industry the sample to be tested is mainly used in, and the temperature required for the test can be judged almost in the environment of use. Then, after understanding the standards that the industry needs to meet, the storage time of the samples in high temperature environment and low temperature environment will be stipulated, plus the number of high and low temperature cycles and the time required for the temperature rise and fall of the high and low temperature test box, it is almost possible to calculate What is the total time required for a high and low temperature test.

If users need to perform high and low temperature testing for a long time without interruption, it is best to choose equipment with guaranteed quality when selecting high and low temperature test chambers to ensure that the experiment will not be forced to stop due to equipment failure during the testing process.

1. High temperature is generally 48 hours, and low temperature is 24 hours.

2. The high and low temperature test is used to determine the adaptability of the product for storage, transportation and use under high temperature climatic conditions. The severity of the test depends on the temperature of the elevated temperature and the duration of exposure.

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

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

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

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

For the electronic product industry, the high temperature power aging test widely used by manufacturers generally takes several or dozens of hours. The main function is to screen components with multiple potential failures. In fact, different industries have different requirements, and the actual high and low temperature test duration is generally done according to the specific needs of customers.
