Formal Definition of CBM (condition based maintenance) The gathering, processing, and analyzing of relevant data and observations, in order to make good and timely decisions on whether to: • Intervene immediately and conduct maintenance on an equipment at this time, or to • Plan to conduct maintenance within a specified time, or • Continue operating the equipment until the next CBM inspection interval. Where applicable and effective, CBM is the preferred form of maintenance. CBM is also known as on-condition maintenance and predictive maintenance. Applicable: Practical, realistic.Effective: Increases reliability (availability, productivity, quality, safety, economy) without exceeding any environmental regulated levels.
