Low air pressure test chamber temperature overshoot/recovery time test procedure


Low pressure test chamber temperature overshoot test steps:
1. The temperature overshoot test and the temperature deviation test, and the average temperature change rate test every 5 minutes are simultaneously performed.
2. During the process of heating or cooling the equipment, measure and record the highest or lowest temperature value outside the allowable deviation range of the nominal temperature.
Low pressure test chamber temperature overshoot recovery time test steps:
1. The temperature overshoot recovery time test and the temperature overshoot test are performed simultaneously.

2. When performing the temperature overshoot test, record the time required for the temperature to exceed the nominal temperature tolerance range and start to stabilize within the nominal and temperature tolerances, in min.
