Vacuum Method Leak Testing
6.4.2.1.
Outside-In Leak Testing
In this method, the test object is evacuated (direct connection to vacuum inlet test port
KF-25) and the user sprays helium to verify test leak integrity. This method allows for
leak location.
If test objects are small enough, a plastic bag can be placed over the test object and
helium sprayed into bag. This method ensures helium application is global around the
entire part
