Abstract:
Various ASTM test methods are currently used to test the oxidation properties of lubricating oils. They vary based on the type of lube oil they are attempting to test and the aim is usually to emulate under laboratory conditions, the real world conditions that the oils are subjected to. The primary factors that are usually available in the lab to simulate such a real life condition are the duration of the test, the temperature the sample is subjected to, catalyst that can be used to speed up the oxidation process, the atmosphere and condition under which the sample is tested etc. By changing these conditions for different kinds of oils, various ASTM oxidation tests have been created to study the oxidation and thermal performance of lubricants in the laboratory. Some of the lubricating oils that ASTM accounts for in their oxidation testing include hydraulic, R&O, turbine fuel oils, gear oils, greases, engine oils etc.. The test methods include ASTM D 942 - Oxidation Characteristics of Inhibited Mineral Oils, ASTM D 2893 - Oxidation Characteristics of Extreme Pressure Lubricating Oils, and ASTM D 5763 - Oxidation and Thermal Stability Characteristics of Gear Oils Using Universal Glassware just to name a few. The goal of this study is to look at these various test procedures already developed, and to attempt to create a more universal procedure / apparatus that can be modified by the user in their laboratory to run their own research protocols, while developing newer and longer lasting lube oils.
