Test Procedures
1.1.Equipment Preparation
Verify chamber integrity, power supply, and control system calibration.
Confirm vacuum pump and pressure regulation system functionality.
Prepare test samples and arrange securely inside the chamber.
2. 2.Parameter Setting
Set desired temperature and pressure profiles according to test requirements.
Adjust pressure change rate to simulate ascent or descent conditions.
Enable data logging and monitoring functions.
3. 3.Test Execution
Start the chamber and allow environmental parameters to reach target values.
Monitor temperature and pressure uniformity throughout the test duration.
Record any deviations or alarms for analysis.
4. 4.Test Completion
Gradually return chamber to standard temperature and pressure conditions.
Safely remove test samples and review data for evaluation.
