The average operating time until failure of a non-repairable asset or component.
Mean Time to Failure (MTTF) is a reliability metric representing the average operating time before a non-repairable asset, component or device fails. It is commonly used to assess the expected service life of items that are replaced rather than repaired, supporting reliability analysis, lifecycle planning and product performance evaluation.
Mean Time to Failure measures the expected service life of non-repairable assets based on historical or predicted performance.
MTTF is primarily applied to non-repairable components such as sensors, electronic devices and consumable items. Repairable equipment is typically evaluated using Mean Time Between Failures (MTBF).
Mean Time to Failure applies to non-repairable assets, whereas Mean Time Between Failures measures the reliability of repairable equipment.
