Air leak testing is conducted by applying pressure or vacuum to a test part, vessel, or system and monitoring it for any presence of leaks in the system. The test object undergoes the following testing procedure:
- Fill / Vacuum time: The test part is sealed and connected to the test equipment. Depending on the test method, the test part is filled with air or gas or vacuumed according to production specifications.
- Stabilization Period: After reaching the set pressure or vacuum level, the system enters a stabilization phase to ensure that there are no temperature or pressure fluctuations within the system that can influence the results.
- Test Period: During this testing period, the test piece is monitored for any pressure changes in the system. Various types of leak testing principles can be followed here depending on the test accuracy. Test results are displayed on the equipment indicating if the product has a leak within acceptable levels or not. Also, the results can be transferred to your PC (monitoring system) via communication protocols.
- Venting: The test air is vented out to the atmosphere and the circuit is open. The test part returns to initial pressure conditions and prepares for the next test.
