3. Applicable Standards
BF-28-2 conforms to the standards of SH/T 0193, ASTM D2272.
4. Scope
This instrument utilizes an oxygen-pressure vessel to evaluate the oxidation stability of new and in-service turbine oils having the same composition (base stock and additives) in the presence of water and a copper catalyst coil at 150°C.
5. Summary of Test Method
The test oil, water, and copper catalyst coil, contained in a covered glass container, are placed in a vessel equipped with a pressure gage. The vessel is charged with oxygen to a gage pressure of 620kpa (90 psi, 6.2 bar), placed in a constant-temperature oil bath set at 150°C, and rotated axially at 100 rpm at an angel of 30°from the horizontal. The number of minutes required to reach a specific drop in gage pressure is the oxidation stability of the test sample.
