Equipment Failure Classifier
Classify equipment failures per ISO 14224. Select equipment type and observed symptoms to identify failure modes, typical MTBF ranges, and maintenance strategies.
Classification Results
Failure Mode Hierarchy
ISO 14224 defines a structured hierarchy for recording reliability data:
- Equipment class — e.g. pump, compressor, motor
- Subunit — e.g. rotating equipment → bearing subunit
- Maintainable item — e.g. bearing, seal, impeller
- Failure mode — observed effect (vibration, leakage, etc.)
- Failure mechanism — root cause (fatigue, corrosion, erosion)
Common Failure Modes per ISO 14224
| Code | Failure Mode | Description |
|---|---|---|
| FTS | Fail to start | Equipment does not start on demand |
| STP | Spurious stop | Unexpected shutdown during operation |
| ELU | External leakage — utility | Leakage of utility fluids |
| ELP | External leakage — process | Leakage of process medium |
| INL | Internal leakage | Leakage across internal barriers |
| VIB | Abnormal vibration | Vibration exceeding acceptable limits |
| OHE | Overheating | Excessive temperature |
| LOO | Low output | Reduced performance (flow, pressure) |
| NOI | Abnormal noise | Unusual sound during operation |
| ERO | Erratic output | Fluctuating or unstable performance |
Note: MTBF values shown are typical industry ranges from OREDA and similar databases. Actual MTBF depends on operating conditions, maintenance quality, and equipment design.
Professional field balancing instruments and vibration analyzers. Detect failures early with condition monitoring.
Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
