...T. W. Selby; S. W. Froelicher; James Secrist The importance of oxidation-resistant turbine oils in the various applications in which turbines are used is difficult to understate. Turbines in themselves are very costly energy-converting mechanisms which, among many other applications, provide much...

...Peter W. R. Smith 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...

...M Pach; HK Zobel; T Norrby Traditionally, long established oxidation tests such as TOST (ASTM D 943-03) and RPVOT (ASTM D 2272-02) in combination with the acid number (ASTM D 974-03) test has been used to screen the oxidation stability of turbine oils. Lately, nevertheless, a new voltammetric...

...VJ Gatto; WE Moehle; TW Cobb; ER Schneller The current turbine oil oxidation bench tests have been in place for many years. Recently, however, the basestocks used to formulate these lubricants have changed significantly. Traditional basestocks, containing high levels of aromatics and sulfur, have...
