The International Organization for Standardization (ISO) created the cleanliness code ISO 4406 to quantify particulate contamination levels per milliliter of fluid at three sizes. The particle sizes range from tiny little chunks to big, irregular shapes, and were grouped into 4 micron, 6 micron and 14 micron sizes. That's why a very valid and important question is: " How do we get and maintain an acceptable fluid cleanliness level?". A Lubrication Reliability strategy consistently uses three words:Īnd when combined they are generally used as cleanliness control and contamination control.Ĭleanliness control is the processes and tools to ensure only clean lubricants are added to the equipment, whereas Contamination Control is the processes and tools to ensure only clean lubricants are operating in the equipmentĬontamination is the major cause of failure in fluid power systems. The number one problem with lubrication today is contaminatio n, and this can be particle contamination or chemical contamination or both. ![]()
