What Does TOST Stand For?

TOST stands for Turbine Oil Stability Test

The Turbine Oil Stability Test (TOST) is a critical assessment used to evaluate the longevity and performance of turbine oils under thermal and oxidative stress conditions. This test measures the oil's resistance to degradation over time, ensuring that it can maintain its lubricating properties and protect turbine components effectively. TOST results are essential for determining oil change intervals and enhancing operational reliability in turbine systems.
