The relationship between temperature, air pressure and duration of high and low temperature and low pressure tests

High and low temperature low pressure test chamber The high and low temperature and low air pressure test is to determine the adaptability of the product for storage, transportation, and use in high/low temperature and low air pressure climatic environments. The severity of the test depends on the temperature, air pressure and exposure duration.

In the high and low temperature and low pressure test, the test sample should first be subjected to the severe level of high temperature test specified in the relevant specifications. If the test sample is to work during the test, it should be tested to ensure that the test sample can work properly. Then the test chamber pressure is reduced to the test pressure specified in the relevant specification while the temperature is maintained at the specified value. This temperature and pressure conditions will be maintained for the specified time.

High and low temperature low pressure test chamber Temperature, air pressure and exposure duration indicated by the test severity level refer to the following table.

Preferred combination of temperature, air pressure and duration
