RPVOT

Definition

RPVOT (Rotary Pressure Vessel Oxidation Test) measures the oxidation stability of a turbine oil. The sample is placed in a vessel that contains a polished copper coil. The vessel is then charged with oxygen then placed in a bath at a constant temperature of 150°C. Oxidation stability is expressed in terms of the time required to achieve a 25.4 psig pressure drop from maximum pressure.

Standard Test Method Used

ASTM D2272

Reporting Measurement

Minutes

Amount of Sample Needed

200 mL

Test Limitation

Test is primarily used for turbine and compressor oils.
