MTTF (Mean Time To Failure)

Examples

1. 01The MTTF of the LED high-bay lamps in the warehouse is about 50,000 hours, so they are replaced on failure, not on a schedule.
2. 02Reliability engineering checks MTTF data from the lamp supplier against its own failure records before changing the strategy.
3. 03MTTF figures help decide how many spare sensors to stock: with 400 units in use, about 20 are expected to fail each year.
