The three basic functions of leak testing are 1) determining if there is leakage or not ( Detection ), 2) measurement of leak rate and 3) leakage location.

Jan 01, 2001 · presents some leak detection techniques and compares their performance with special attention paid to refrigerant leakages. 2 Leak testing methods A leak can be defined as an unintended crack, hole or porosity in an enveloping wall or joint, which must contain or exclude different fluids and gases allowing the escape of closed medium.
