- Content
- This test method describes a standardized process to evaluate an aviation lubricant’s resistance to thermal degradation and to evaluate the fluid’s tendency to corrode a steel specimen. Fluids are evaluated in an environment free of both air and moisture at a specified temperature and for a specified time period.
- Content
- Corrosivity and thermal stability are critical performance parameters of an aviation turbine lubricant. AS5780 defines the performance specification limits for corrosivity and thermal stability, but the corresponding reference (FED-STD-791D, Method 3411) is no longer supported by the sanctioning organization. This test method will specify an updated means for determination of corrosivity and thermal stability as called out in AS5780.
