Explores the evolution of oxidation tests over the past century—TOST, RPVOT, Dry TOST, MAN LTAT, and TOPP—highlighting their role in current and future gas turbine oil formulation and testing. Guide deeper conversations with your customers about test selection and performance standards.
The specifications for high thermal stress turbine oils for modern gas turbines have evolved significantly over the years. With the increasing power output and efficiency of large gas turbines, the demands on turbine oils have also risen.
This document discusses the development of specialized oxidation tests to ensure the performance and long-term stability of these lubricating oils under demanding conditions such as with gas turbines. Historical tests laid the foundation for evaluating oxidation stability, while modern tests like the RPVOT and Dry TOST test have further refined the assessment process.
The introduction of the third generation of turbine oils, tested against varnish formation, highlights the need to incorporate contemporary requirements into standards. In addition, this paper discusses the selection of an appropriate turbine oil and how to ensure long-term stability.
