ASTM D6186 Oxidation Induction Time of Lubricating Oils

ASTM D6186 Oxidation Induction Time of Lubricating Oils

The ASTM D6186 test technique is used to determine the oxidation induction time of lubricating oils exposed to oxygen at a pressure of 3.5 MPa and temperatures of 130 to 210 °C. The results of specimens analyzed using this method are measured in SI units.


    The ASTM D6186 is a standard test method that uses pressure differential scanning calorimetry  (PDSC) to determine the oxidation induction time of lubricating oils. The duration of oxidation induction, as measured under the parameters of this test procedure, can be used to determine oxidation stability. This method is faster than the other oil oxidation tests and just requires a little sample. It can be used for things like research and development, quality control, and specification. 

    Test procedure:

    A little amount of oil is weighed into a sample pan and deposited in a test cell for ASTM D6186.  The cell is preheated to a predetermined temperature and then inflated with oxygen. Until an exothermic reaction occurs, the cell is kept at a constant temperature and pressure. At the given test temperature, the extrapolated onset time is determined and reported as the oxidation induction time for the lubricating oil. 

    Specimen size:

    Lubricating oils are used as test specimens for ASTM D6186 test method.


    As per the ASTM D6186, the sample’s oxidation induction time (OIT) and test temperature are reported to the closest minute.
