Iso 14224
ISO 14224 is an international standard for the petroleum, petrochemical, and natural gas industries that defines a structured data architecture, equipment taxonomy, and failure classification scheme for collecting and exchanging reliability and maintenance data. It specifies four record types: equipment inventory, failure events, maintenance events, and equipment population data, enabling statistically valid failure rate calculations across the equipment life cycle.
In shop floor maintenance, ISO 14224 is applied within CMMS/EAM systems like ServiceGrid, IBM Maximo, or HxGN EAM by implementing a nine-level equipment hierarchy from industry segment to maintainable item. This ensures every failure record traces to a specific, comparable component. Engineers use standardized failure, cause, and maintainable item codes to enable cross-facility benchmarking, bad-actor analysis, and Reliability-Centered Maintenance (RCM) input. The standard enforces consistent terminology—distinguishing failure mode, mechanism, and cause—to ensure data quality for RAM analysis, SIL verification, and risk assessments.
How does ISO 14224 differ from RCM (SAE JA1011)?
ISO 14224 uses FMECA-derived terms where failure mode is the effect observed, while RCM defines failure mode as the event causing failure, with taxonomy: object part → damage → cause.
Is ISO 14224 applicable outside oil/gas?
Officially scoped to petroleum/petrochemical/natural gas, but its data structure and taxonomy are increasingly adopted in EAM systems for cross-industry reliability benchmarking.
What data minimums does ISO 14224 require?
Equipment attributes (taxonomy), failure cause/consequence, maintenance action/resources, and equipment population count, which is critical for calculating failure rate per unit time.
