ABSTRACT:
A semi-quantitative method for determining the amount of water in contaminated oil samples wherein a small sample of contaminated oil is placed in one or more compartments of a container. An equal size sample of reference oil of the same composition as the test oil, but containing a known quantity of water, is placed in one or more compartments of said container. The container is then heated rapidly and bubbles formed in the contaminated oil are compared with bubbles formed in the reference oil, thereby bracketing the water content rapidly (less than 5 minutes) with reasonable accuracy.
