Test Method: - 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.Standard: - Conforms to the specifications of: ASTM D2112, D2272, D4742; IP 229Features & Benefits:-1) Type of Bath: - Electrically heated immersion heater.2) Max Working Temperature :- 200 Degree C3) Continuous Working Temperature :- 200 Degree C4) Capacity: - 70 Ltr bath with SS body & top cover.5) Mounting: - 2 Place rotating pressure vessels oil bath on castors.6) Drive: - Heavy duty drives motor to rotate pressure vessel at 100 rpm and is housed below the oil bath.7) Pressure Vessel: Rotating pressure vessel constructed of stainless steel with stem and valve to receive pressure transducer.8) Angle:- Pressure vessel is held at an angle of 30°9) Mapping: - Pressure mapping 0-200 psi.10) Accessories: Catalyst wire, glass liners with PTFE-cover, an ASTM 96c thermometer, & 'O' ring supplied with the unit.11) Data Logger: Automatic pressure digital data logger with pc interfacing software supplied on CD-ROM with pressure sensor.12) Heater :- Immersion heater13) Accuracy :- +/- 0.3 Degree C14) Readability :- +/- 0.1 Degree C15) Temperature controller :-a.
