Basic Principle of Bubble Leak Testing - Immersion Leak Technique
In Bubble Leak Testing (BLT), a gas pressure differential is established across a pressure boundary to be tested. A test liquid is then applied in contact with the lower pressure side of the pressure boundary. Gas leakage through the pressure boundary can then be detected by observation of bubble formed in the detection liquid at the exit points of leakage through pressure boundary. This technique provides immediate indications of the large leaks, 10-3 to 10-5 Pa.m3.s-1 or (10-2 to 10-4 std.cm3.S-1)
