I. Purpose And Scope

    This instrument is designed and manufactured in accordance with Method B of the American Society for Testing and Materials (ASTM) D2272-2009 "Determination of Oxidation Stability of Lubricating Oils" standard and the "NBSHT 0193-2022 Rotary Oxygen Bomb Method" standard. It is suitable for measuring the oxidation stability of oil products specified in the standard at two temperatures of 150 ℃ or 140 ℃. This instrument can be used to determine the oxidation stability of new and in-use turbine oils with the same composition (base oil and additives). (In the case of inaccurate requirements for experimental data, it can also be used to evaluate the oxidation stability of new mineral insulating oils containing 2,6-di-tert-butyl-p-cresol as a rapid evaluation method.)
