OEL is a global metric designed to assess the critical areas that may compromise an effective program of lubrication. It is the implementation in similar way of the Metrics OEE (Overall Equipment Efectiveness) used by the production departments, as the multiplication of three measurements of compliance:
1.Compliance Percentage of lubrication with the elements related to preventive maintenance tasks (PCpmt)
2.Percentage of compliance with the objectives of control tasks of the Pollution Control Tasks (PCpct) and
3.Percentage of compliance with the objectives of lubricant quality tasks (PClqt).
