Bombing Test
The part is sealed and cannot be evacuated nor pressurised.
Place the test item in a chamber and pressurise it (bombing chamber). Should a leak be present, the tracer gas will be forced into the part due to the gas pressure. Once the part has been through the bombing process, the process is reversed. The part is placed inside a vacuum chamber and the chamber is evacuated. Any tracer gas that was forced inside the part will now be forced out and measured by the leak detector.
Main advantages
- Only solution to test sealed components with high sensitivity
- High repeatability
