ABSTRACT
The load Fv is the vertical component of the force, acting on the ball bearings. It will be measured with an accuracy of at least 2% of the maximum value during the test.
The COD is measured on the specimen by means of transducers, or a
clip gauge, which should be fixed at the same level as the axles of the ball bearings. Alternatively, the COD can also be measured on a lower level. The measured values
