Introduction To Leak Testing
Helium Leak test. In leak testing a pressure difference between the outer and the inner side of the object to be examined is produced. Subsequently, the amount of gas or liquid which is passing through a leak is measured. In the helium leak test helium is used as a search gas, from this the nomination of the method.
