Definition
A service interval is the specific time, runtime, or usage span (such as every six months, 2,000 operating hours, or 50,000 cycles) between two occurrences of the same recurring maintenance task. It is the concrete unit that maintenance interval optimization adjusts, and the building block a maintenance schedule is built from.
Key facts
- A concrete unit of measure (calendar time, operating hours, or usage cycles) not a strategy or planning process.
- The specific value that maintenance interval optimization reviews and adjusts based on evidence.
- Sourced initially from OEM recommendations, then refined using site-specific failure and inspection history.
- Multiple service intervals for different tasks on the same asset are what a maintenance schedule coordinates.
Why does Service interval matter in maintenance?
A service interval is the specific span (a number of days, operating hours, or cycles) that separates two occurrences of the same task, such as a filter change every 500 hours or a calibration check every twelve months, defining when the next occurrence of that task is due.
How do maintenance teams apply Service interval?
Maintenance interval optimization is the activity of reviewing and adjusting a service interval's value based on evidence. Maintenance scheduling is the separate activity of assigning the resulting due dates to specific calendar slots and personnel. A service interval is the unit of measure both of those activities work with.
