Rotating Pressure Vessel Oxidation Test

Significance. Measures the resistance of an oil to oxidation when subjected to accelerated oxidation in a sealed chamber filled with pure oxygen under pressure and at elevated temperatures. This is influenced by the quantity and type of antioxidants, the presence of natural inhibitors in the base oil, and the resilience of the base oil to oxidation. As a lubricant absorbs oxygen, pressure in the sealed chamber drops. The results of this test are reported as the time (minutes) until the pressure drops to a predetermined level.
