Bubble Point Integrity Testing - Scott Labs

A bubble point test is a non-destructive method of integrity testing that allows the user to correlate their results with manufacturer-determined values that indicate proper function. Bubble point testing is not a direct measurement of pore size. A bubble point test returns the pressure at which the surface tension of water inside filter media ...
