Equipment History
Equipment history is the chronological record of an asset's failures, maintenance, inspections, changes, costs, parts, readings, and operating events.
What this term means in maintenance
Equipment history is the chronological record of an asset's failures, maintenance, inspections, changes, costs, parts, readings, and operating events.
What equipment history includes
An asset history may show:
- Work requests
- Work orders
- Preventive maintenance
- Failures
- Downtime
- Parts used
- Labor
- Contractor work
- Calibration
- Condition readings
- Modifications
- Warranty events
- Documents
Practical example
A repeated pump seal failure is reviewed using earlier work orders, parts, alignment readings, operating conditions, and root cause actions.
How equipment history is used
History supports troubleshooting, bad-actor identification, PM optimization, replacement decisions, warranty claims, spare-parts planning, audits, and cost analysis.
Data quality
History is only as useful as the records feeding it. Consistent asset identity, work completion, failure coding, and dates are essential.
Common mistake
Recording work against the production line instead of the failed component can leave the component's history incomplete.
How this term differs
Equipment History is the chronological collection of records associated with an asset. It is related to Maintenance Logbook, Audit Trail, and Maintenance Record, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
