Maintenance Activity Supporting Activity Describes a maintenance or supporting activity where we are not sure of its classification Unspecified Activity p is an adjust activity = Def p is a process and there exists a material artifact m that has a function f and participates in p at some time. The following is also true: - m has state at some time some sub-optimal operating state s1 and optimal operating state s2 - f is impacted by s1 - p occurs at some time tp - tp finishes s1 and p starts s2 Bringing any out of tolerance condition into tolerance.

The following is also true: - m is the bearer of a control and monitoring role ry - m has state at some time some failed state or degraded state or operating state s and operating state s2 - if s is failed state or degraded state then s disables f - if s is sub-optimal operating state then s impacts f - p occurs at some time tp: tp finishes s and tp starts s2 - p is is prescribed by some part of a preventative maintenance strategy ps A task involving testing and adjustment of instrumentation to assess and restore function A BFO:Process performed on equipment instrumentation, to estimate the ability of the instrumentation and restore if needed. calibrate re-calibrate calibrate p is an diagnose activity = Def p is a process and there exists a material artifact m that has a function (or capability) f and participates in p at some time. The following is also true: - m has state at some time some degraded state or failed state state s - f is disabled by s - s is observed in some observation process The cause of failure, or degradation, is investigated but no maintenance action performed, or action is deferred.

The following is also true: - m has state at some time some state s - s is observed in some observation process o - p is prescribed by some part of a preventative maintenance strategy ps Periodic, careful scrutiny of an item carried out with or without dismantling.
