WebNote: Equipment MTBF value represents the expected rate of failure at a specific operation profile, under specific environmental conditions. Conversion factors may be required to adapt the MTBF value for different conditions. Prediction methods usually provide “end item” MTBF according to the following MTBF formula: MTBF=1/(λ 0 ·Π S ·Π ... This critical relationship between a system's MTBF and its failure rate allows a simple conversion/calculation when one of the two quantities is known and an exponential distribution (constant failure rate, i.e., no systematic failures) can be assumed. The MTBF is the expected value, average or mean of the exponential … See more 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 arithmetic mean (average) … See more Mean time between failures (MTBF) describes the expected time between two failures for a repairable system.
