ISO 14224 Predictive Maintenance

In one sentence

Puts every piece of equipment into one reliability taxonomy so that failure rates mean the same thing across all fields, and maintenance is planned from them.

The problem

Two fields in the same company report pump reliability differently because they classify equipment, failure modes and criticality differently. Comparing them is impossible, so capital and spares are allocated by argument rather than by evidence.

How it works

Equipment registers and maintenance history are mapped onto the ISO 14224 taxonomy — equipment class, boundary, failure mode, failure mechanism — with the mapping reviewed by the reliability engineer rather than accepted automatically. Reliability statistics and remaining-life models are then computed on that common basis and used to set maintenance intervals.

Data required

  • Equipment register with tags, classes and boundaries
  • Maintenance work-order history, preferably five years or more
  • Failure reports with the mode and mechanism as found
  • Operating hours and duty context per asset

What you get

  • ISO 14224-conformant reliability database across the portfolio
  • MTBF and failure-mode distribution by equipment class, comparable between fields
  • Interval recommendations and criticality-weighted spares policy

What it cannot do

Mapping a legacy maintenance history to ISO 14224 is a substantial manual effort; typically forty to sixty per cent of historical work orders lack enough detail to classify the failure mode, and no automation recovers information that was never written down. Those records are marked unclassified rather than assigned a plausible mode, which keeps the statistics honest and makes the gap visible.

Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
