What is time-based maintenance?
Time-based maintenance (TBM) is maintenance performed on equipment based on a calendar schedule. This means that time is the maintenance trigger for this type of maintenance.
How it works
Time-based maintenance is performed on a calendar schedule. A maintenance plan for a piece of equipment is put together that needs to be performed regularly. An example is the maintenance that is done on an air-conditioner every year before summer. With the maintenance plan in place, the maintenance is performed each time the calendar rolls over the specified number of days.
