Oxidation Characteristics of Inhibited Mineral Oils
Sludging and Corrosion Tendencies of Inhibited Mineral Oils
Oxidation Stability of Distillate Fuel Oil (Accelerated Method)
Oxidation Characteristics of Extreme-Pressure Lubrication Oils
Test Method
Evaluates oxidation stability by subjecting the sample to a temperature of 95?C in the presence of oxygen or dry air. For inhibited mineral oils, the sample is reacted with oxygen in the presence of water and an iron-copper catalyst.
Oxidation Stability Apparatus
- Thirty and sixty-place liquid baths for high volume testing requirements
- Eight and twelve-place liquid baths for benchtop placement
- Twelve-place solid block bath
- Conforming to ASTM and related test method specifications
- Special baths for ASTM D2893 and AOCS CD12-57 tests
Eight and Twelve-Place Oxidation Baths
- Conforming to ASTM and related test method specifications
Constant temperature baths with solid state temperature control, calibrated flow-meters and condenser water manifold for oxidation stability tests on fuels and lubricants. Individual flow-meters and control valves for each oxidation cell deliver air flow at the rate of 3L/h. Condenser water manifold has individual control valves for each cell. Microprocessor PID control provides quick temperature stabilization without overshoot, and the bath is protected by a redundant over temperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Display provides actual setpoint temperature values in ?C/?F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Double-wall insulated baths are equipped with copper immersion heaters and a 1/20 hp circulation stirrer. Stainless steel bath interior has a built-in support rack and overflow/drain to immerse the test cells at the required depth. Order oxidation cell glassware and accessories separately.
