Southwest Research Institute (SwRI) offers the foaming tendency laboratory evaluation method, ASTM D 892, which determines the foaming characteristics of lubricating oils at specified temperatures in the laboratory. The means of empirically rating the tendency to foam and the stability of the foam are described in the foaming tendency test method.

ASTM D 892 Evaluation Parameters
A sample, maintained by a temperature of 24°C, is blown with air at a constant rate for 5 minutes and then allowed to settle for 10 minutes. The volume of foam is measured at the end of both periods. The test is repeated on a second sample at 93.5°C and then, after collapsing the foam, at 24°C.
Pass/Fail Criteria
At the end of the ASTM D 892 test, the following information is reported:
-
Optional blending (if implemented)
-
Volume of kinetic foam before air disconnect
-
Foam stability
-
Collapse time
-
Foaming tendency (static foam)
-
Total volume before air disconnect
-
Volume of static foam for selected option after disconnect
