OIL ANALYSIS TESTS

Foaming

This test is used to determine the foaming characteristics of lubrication oils.

Large industrial turbines and wind turbines have a need to control foaming to ensure adequate lubrication and to protect the environment from spillages. Circulation oils usually have an additive to keep foaming under control. To determine if the additive is still functioning fully, a measured amount of air is blown at a constant rate into an oil at a specified temperature, the foam produced is measured and checked to see how long it takes to collapse.
