s or equipment. Its central theme involves directing corrective actions aimed at failure root causes, not active failure symptoms, faults, or machine wear conditions.
A typical proactive maintenance regimen involves three steps:
- (1) setting a quantifiable target or standard relating to a root cause of concern (e.g., a target fluid cleanliness level for a lubricantLubricantA lubricant is a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles and of distributing heat...
), - (2) implementing a maintenance program to control the root cause property to within the target level (e.g., routine exclusion or removal of contaminants),
- and (3) routine monitoring of the root cause property using a measurement technique (e.g., particle counting) to verify the current level is within the target.
