Oxidation Stability By Rotating Pressure Vessel Method

Oxidation Stability by Rotating Pressure Vessel Method

These standards describe a method for the determination of tendency of lubricating oils to deteriorate on oxidation under specified conditions. The sample is subjected to severe oxidations by heating at 2000C along with passing air through it at specific flow rate and duration. Kinematic Viscosity & Rams bottom carbon residue is determined of the oxidized oil. IP / IEC test standard processes prescribes the use of metal catalyst wire / metal specimen to carry test processes.

Salient Features

These methods used to evaluate the oxidation stability of new and in-service engine, turbine and insulating oils in the presence of water and a copper catalyst.
