The lubricant is tested in a frictional system consisting of a cuboid test block through which the test loads are applied onto a rotating ring. The test load is changed by degrees until the OK load and seizure load have been established. The wear is determined by individual weighing of the test pieces. The test duration for each stage is 10 minutes.

The test device establishes the characteristics of lubricants with respect to their behavior in mixed-friction conditions, defined as

• OK values
• Wear values
