→ od:hasLippertNote → "Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation.
MTBF can be calculated as the average time between failures of a system.
The term is used for repairable systems, while mean time to failure (MTTF) denotes the expected time to failure for a nonrepairable system.
The definition of MTBF depends on the definition of what is considered a failure for the system."@en
