The report describes test methods and procedures used in the study of the oxidation-corrosion-deposition O-C-D characteristics of aircraft turbine engine lubricants employing a glassware-type apparatus. Development and evaluation of a light meter device for quantitative measurement of glassware deposits are also discussed. An extensive experimental effort using eight MIL- L-7808-type lubricants is described. The study encompassed an investigation of the factors of time, temperature, moisture, and metal types in relation to lubricant breakdown in an oxidizing air atmosphere. A similar, less extensive program was conducted for four lubricants using an inert nitrogen atmosphere.
