How leak test is performed?

A leak test is typically performed by pressurizing a system with air, gas, or liquid and monitoring for pressure changes over time. In the case of air or gas, a soapy solution may be applied to joints and seams to detect bubbles that indicate leaks. Alternatively, a vacuum test can be conducted by creating a vacuum and checking for pressure loss. Advanced methods include using helium mass spectrometry, where helium is introduced and its presence is measured to identify leaks.
