Contamination is by far the most common cause of faults and failures in oil lubricated machines and hydraulic systems. The adequate cleanliness of lubricating and hydraulic oils is often viewed more as a necessary evil as the key to trouble free operation. At the same time excessive purity requirements can be found in the market born partly of uncertainly and partly from commercial interests.

Like no other measurement method particle counting and the system of cleanliness classes is often misunderstood and misinterpreted in practice. Different counting methods can lead to different cleanliness classes that are liked attributed solely to wrong sampling procedures. However, particle counting and cleanliness classes have a different nature in comparison to other test methods, such as the viscosity measurement. This fact has to be considered in interpretation of the results to be applied successfully in practice.

The online course offers a thorough, practical introduction to the subject and demonstrates the efficiency of particle counting technology using case studies.
