What Does Mean Time Between Failure (MTBF) Mean?

Mean Time Between Failures (MTBF) is defined as 1 divided by the failure rate. If, for example, there is a system with 948 failures in 106 hours, the average time between failure is 106 hours/948 (=1054 hours). The MTBF figure is not a guaranteed failure-free period. It is a mean value (average) of operating times between failures.
