Foam Bath
Foam Bath
Foaming of lubricating oils in applications involving turbulence, high-speed gearing or high volume pumping can cause inadequate lubrication, cavitations, 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.
