Primes¶
- Maintenance
- Unlike repair, which responds to failure after it occurs, and unlike improvement, which extends capacity or scope, maintenance works ahead of catastrophic failure—sustaining stable function over time despite continuous degradation, as Moubray (1997) develops in his canonical treatment of reliability-centered maintenance.
This sourceFoundational RCM text: explicitly reframes maintenance from reactive repair toward proactive, function-preserving interventions tied to measured failure modes and degradation patterns.

- Temporal Decay and Degradation
- This shifts thinking from reactive crisis ("the system broke") to proactive lifecycle management ("the system followed its degradation curve, and we failed to restore it on schedule"), the explicit reframing Moubray (1997) operationalizes as Reliability-Centred Maintenance.

Mechanisms¶
- Case History
- Reliability-centred maintenance
This sourceReliability-centered maintenance selects preventive and condition-monitoring tasks by analyzing failure modes and consequences.
- Reliability-centred maintenance
- Condition-Monitoring Sensor
- A subtler trap is the P-F interval: if the sampling interval is longer than the window between detectable onset and functional failure, the sensor is real but useless — decline is happening faster than it can be caught.
This sourceDefines the P-F interval and explains that condition-monitoring intervals must be short enough to detect deterioration before functional failure.

- Infrastructure Preventive Maintenance
- The interval between when a fault first becomes detectable and when it causes functional failure — the P-F interval — is the window this program is built to exploit.
This sourceDefines the P-F interval as the time between detectable potential failure and functional failure and uses it to set on-condition task frequency.
- The interval between when a fault first becomes detectable and when it causes functional failure — the P-F interval — is the window this program is built to exploit.
- Maintenance Schedule
- The gap between first detectable sign and functional failure sets the outer bound on how long an interval can safely be.
This sourceDefines the P–F interval from detectable potential failure to functional failure as the upper bound governing inspection-task frequency.

- Maintenance Trigger
- A Maintenance Trigger is the core of condition-based maintenance: it fits wherever a measurable indicator leads failure with enough warning to act, replacing both wasteful fixed-calendar servicing and reactive run-to-failure.
This sourceUses detectable potential-failure conditions and their warning interval to trigger condition-based maintenance early enough for preventive action.

- Preventive Inspection Schedule
- But a slightly frayed hoist cable, still well within safe limits, gets logged as a watch item — caught inside the interval between detectable and dangerous, which is exactly what a good inspection cadence is tuned to catch.
This sourceDefines the P–F interval from detectable potential failure to functional failure and relates inspection cadence to that interval.

- Scheduled Cleaning or Scraping Protocol
- It is the right choice when fouling pressure is steady and predictable, or when inspection would cost more than just cleaning on a sensible rhythm — which is why it dominates settings where the load is regular and the interface easy to work.
This sourceReliability-centered maintenance uses scheduled restoration or discard for predictably age-related deterioration and considers whether condition inspection is technically feasible and worth doing.

- Weak-Signal Recovery Test
- … that the latest gain reduction has pushed two of those early signatures below the alert threshold, the team learns it has traded nuisance alerts for a blind spot precisely where the monitoring earns its keep — the early part of the P-F interval, the run-up between the first detectable sign and functional failure.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 10 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
