Rotating pressure vessel oxidation test (RPVOT)
The Rotating Pressure Vessel Oxidation Test measures an oil's oxidation stability. The oil sample is placed in a vessel containing a polished copper coil. The vessel is then charged with oxygen and placed in a bath at a constant temperature of 150 degrees Celsius. Stability is expressed in terms of the time it takes to achieve a pressure drop of 25. 4 pounds per square inch (psig) pressure drop from maximum pressure.
