Documented PMT. Rigorous. formal documentation of postmaintenance
testing required, when specified by the equipment owner.

Maintenance Job Request (MJR). Means of obtaining maintenance services,
available on both paper and electronic mediums and initiated by maintenance
customers. An MJR is normally issued to Maintenance Planners and
Estimators and is used to define, plan, and execute maintenance activities. It
serves as documentation of a deficient equipment condition and requires
detailed documentation of work performed, spare parts, procedures, or testing
to verify that maintenance was performed correctly. The MJR may also serve
as documentation for completion of minor maintenance activities such as
lubrication, light-bulb replacement etc. ("MJR" is the equivalent of a "Work
Request")

policy, comply with external directives, or meet operational objectives in a
consistent manner. A procedure provides necessary delineation of roles,
responsibilities, action steps, and requirements.

2.12
Periodic Maintenance. Maintenance activities accomplished on a routine basis
(typically based on operating , hours or calendar time). Periodic Maintenance
includes inspections, lubrications, and technical safety specifications
surveillance (functioning testing, bearing temperature, pump speeds, etc.).
2.13
Planned Maintenance. Preventive maintenance activities performed prior to
structure, system, or component failure and may be initiated by predictive or
periodic maintenance results, by vendor recommendations, or by
experience/lessons learned. These include items such as scheduled valve
repacking, replacement of bearings as indicated from vibration analysis, major
or minor overhauls based on experience factors or vendor recommendations
and replacement of known life-span components. For example, repacking a
valve due to packing leakage would be corrective maintenance, but scheduled
repacking prior to leakage would be planned maintenance.
