Oxidation and the Testing of Turbine Oils by ASTM International, C.A. Migdal, A. B. Wardlow, J.L. Ameye

By ASTM International, C.A. Migdal, A. B. Wardlow, J.L. Ameye

Ten peer-reviewed papers disguise the newest tendencies on agony issues, evolving lubricant /antioxidant additive applied sciences, and altering gear designs and working stipulations, with a spotlight on how those elements impression oxidation. It addresses tips on how to enhance present ASTM bench checks used as predicative instruments for measuring oxidative degradation, together with: D 943 Oxidation features of Inhibited Mineral Oils; D 4310 Sludge Tendency; D 2272 Oxidation balance of Steam Turbine Oils by way of Rotating strain Vessel. STP 1489 is a necessary source to these within the lubricant and turbine undefined, together with unique gear brands, finish clients, lubricant manufacturers, lubricant additive providers, try out gear brands, and traditional attempt procedure builders.

Org Peter W. R. Smith1 Modern Turbine Oil Oxidation Performance Limits—Meeting and Measuring Them—A Shell Perspective ABSTRACT: This paper outlines some of the significant changes in turbine oil oxidative stability requirements over the past five to ten years, and illustrates how these have been met using mineral oil-based products with differing antioxidant systems. It also considers possible future requirements and how these may be met. Use of a modified Federal Test Method 5308, and ASTM tests D 2272, D 4310, and D 943 in formulating new turbine oils and evaluating their oxidative stability is also described and contrasted.

34 OXIDATION AND THE TESTING OF TURBINE OILS FIG. 7—FTIR: carboxylic acids. • A reduction in oxidative stability as measured by RPVOT. • Small amounts of oxidation byproducts are visible at 1714 cm−1 ͑Fig. 7͒. Discussion of Sample B The phenol antioxidants appear to do an adequate job of protecting the base oil and preventing the formation of deposits or base oil oxidation. In addition, the phenol intermediaries and degradation byproducts do not create deposits in this experiment. The viscosity and acid number is not impacted throughout the experiment, suggesting a high quality basestock.
