This data sheet provides guidance on the maintenance of used turbine oils. In operation turbine oils can degrade by thermal, chemical, physical and mechanical processes and normally these processes cause a deterioration in oil performance. In order for the use of turbine oils to be cost effective they should have a long life and be compatible with the system in which they are used. To achieve these goals the data sheet recommends the analysis of selected oil properties and the intervals at which this examination should be carried out. In addition, warning limits are indicated for these properties and the measures required to restore oil quality when these values are reached.

The data sheet is valid for lubricating and hydraulic oils of ISO viscosity classes VG 32, 46 and 68 that, when new, met the requirements of DIN 51515-1 and DIN 51515-2 turbine oil specifications. Part A of this datasheet is not applicable to phosphate ester fire-resistant hydraulic fluids.
