MAINTENANCE TERMS AND DEFINITIONS (Part 1)

This section presents some terms and definitions directly or indirectly used in engineering maintenance:
 

·         Maintenance: All actions appropriate for retaining an item/part/equipment in, or restoring it to, a given condition.

·         Maintenance engineering: The activity of equipment/item maintenance that develops concepts, criteria, and technical requirements in conceptional and acquisition phases to be used and maintained in a current status during the operating phase to assure effective maintenance support of equipment.

·         Maintenance Management:   Maintenance management is the collective term for describing the management process of leadership and organization, planning and scheduling, preventive maintenance, condition monitoring, execution of maintenance repairs, recording, root cause failure analysis, spare parts management, and management of technical data supporting the processes above.

·         Preventive maintenance: All actions carried out on a planned, periodic, and specific schedule to keep an item/equipment in stated working condition through the process of checking and reconditioning. These actions are precautionary steps undertaken to forestall or lower the probability of failures or an unacceptable level of degradation in later service, rather than correcting them after they occur.

·         Corrective maintenance: The unscheduled maintenance or repair to return items/equipment to a defined state and carried out because maintenance persons or users perceived deficiencies or failures.

·         Predictive maintenance: The use of modern measurement and signal processing methods to accurately diagnose item/equipment condition during operation.
