MISMO 35A Oxidation Stability Test Apparatus, RBOT/TFOUT As Per ASTM D 2212 / ASTM D 2272
The RBOT procedure employs severe oxidation conditions to rapidly determine oxidation stability. Suitable for both new and in-service oils, the RBOT method is applicable to many types of petroleum oils. The sample is oxidized in the presence of water and a copper catalyst in a stainless steel pressure vessel under an initial pressure of 90psi (620kpa). Pressure inside the vessel is recorded electronically or mechanically while the vessel is rotated at 100rpm at constant temperature, and the amount of time required for a specified drop in pressure is the oxidation stability of the sample. A variation of the RBOT method is the “Thin Film Oxidation Uptake Test” (TFOUT) for gasoline automotive engine oils.
