RPVOT-Rotating Pressure Vessel Oxidation Test

RPVOT - Oxidation stability testing of steam turbine oils per ASTM D2272

The Rotating Pressure Vessel Oxidation Test (RPVOT), formerly known as RBOT, evaluates the remaining oxidation test life of in-service turbine and other oils; a good indicator of oxidative potential.


To determine lubricant’s resistance to oxidation and sludge formation using accelerated test conditions, involving: high pressure. high temperature, oxygen, the presence of water and active metal catalysts.

Where the RPVOT is performed, the results should be considered in concert with other tests, such as varnish potential (QSA and/or MPC) and direct measurement of phenolic and amine-based oxidation inhibitors (RULER instrument), to truly gauge the remaining life and health of the lubricant.
