Pasol Oxidation Stability Analyzer

Full automatic dry vessel oxidation stability analyzer

  1. General Details

    Pasol Oxidation Stability Analyzer utilizes an oxygen pressured dry vessel to evaluate the oxidation stability of new and used oils in the presence of water and a copper catalyst coil at 150°C according to ASTM D2272 (RPVOT), D2112, D4742, D942 and IP229 standards.

    • RPVOT – ASTM D2272  – Standard Test Method for Oxidation Stability of Steam Turbine Oils by Rotating Pressure Vessel
    • TFOUT – ASTM D4742  – Standard Test Method for Oxidation Stability of Gasoline Automotive Engine Oils by Thin-Film Oxygen Uptake
    • TFOUT – ASTM D7098  Catalyst B – Standard Test Method for Oxidation Stability of Lubricants by Thin-Film Oxygen Uptake
    • ASTM D942 – Standard Test Method for Oxidation Stability of Lubricating Greases by the Oxygen Pressure Vessel Method

    Oxidation stability is a chemical process that occurs when lubricating oil is effected by oxygen. High working temperature, water, acids, and catalysts speed up the oxidation process. Remaining life of a lubricant is shortened especially at high temperatures. Additionally, oxidation causes an increase in the viscosity, as well as varnish and sludge deposits.

    The Rotating Pressure Vessel Oxidation Test (RPVOT) is a method to measure resistance to oil oxidation instead of the oxidation that is already present in the oil as other methods offer.

    Oxidation in oils, such as lubricating, hydraulic, pump, and other oils, is one main cause of mechanical malfunction. Therefore monitoring oxidation resistance of oils help to prevent machinery break downs.
