ASTM D943 - DIN 51587 - ISO 4263 - Test Method for Oxidation Characteristics of Inhibited Mineral Oils
This test method is used to evaluate the oxidation stability of inhibited steam-turbine oils in the presence of oxygen, water, and copper and iron metals at an elevated temperature. The test method is also used or testing other oils such as hydraulic oils and circulating oils having a specific gravity less than that of water and containing rust and oxidation inhibitors.
ASTM D2274 - EN ISO 12205 - IP 388 - Oxidation Stability of Distillate Fuel Oil (Accelerated Method)
This test method covers the measurement of the inherent stability of middle distillate petroleum fuels under specified oxidizing conditions at 95°C.
ASTM D4310 - Determination of the Sludging and Corrosion Tendencies of Inhibited Mineral Oils
This test method is used to evaluate the tendency of inhibited mineral oil based steam turbine lubricants and mineral oil based anti-wear hydraulic oils to corrode copper catalyst metal and to form sludge during oxidation in the presence of oxygen, water, and copper and iron metals at an elevated temperature. The test method is also used for testing circulating oils having a specific gravity less than that of water and containing rust and oxidation inhibitors.
