Foam Test Apparatus Foaming of lubricating oils in applications involving turbulence, high speed gearing or high volume pumping can cause inadequate lubrication, cavitation, overflow and premature oxidation. The sample is blown with a controlled volume of air at different specified temperatures. The resultant foam is measured at the end of each aeration period and at different intervals afterward.
