Method description:
Automatic method for measuring oil cleanliness class with a laser particle counter using a dilution technique that eliminates interference from water contamination and the presence of soluble sludge.
Interpretation of results:
Mechanical contamination in the oil is the most destructive factor for the life of equipment. The higher the purity class code, the worse the oil purity class. A deterioration of oil cleanliness by one class doubles the amount of contamination in the sample for a given range. Oil cleanliness should meet the requirements of equipment manufacturers. The higher the pressures, speeds and smaller the process clearances, the better the cleanliness class should be.
