mean time to failure. The average period of time that a component will work until failure.

Mean Time to Failure. The mean time expected for the first failure of an item. It is meant to be the mean time over an infinite period of time for fully repairable items and for replaceable ones with new spares. MTTF is equal to MTBF.

mean time to failure. The average or mean time between initial operation and the first occurrence of a failure or malfunction, as the number of measurements of such time on many pieces of identical equipment approaches infinity.

Mean Time To Failure. This is the average length of time that the system will remain in service before failing. You want this to be as long as possible.

Mean Time to Failure. The mean time expected to the first failure of a piece of equipment. It is a statistical value and is meant to be the mean over a long period of time and large number of units. For constant failure rate systems, MTTF is the inverse of the failure rate. If failure rate is in failures/million hours, MTTF = 1,000,000 / Failure Rate for components with exponential distributions. Technically MTBF should be used only in reference to repairable items, while MTTF should be used for non-repairable items, but MTBF is commonly used for both repairable and non-repairable items.

Mean Time To Failure. This is a common measure of software reliability.

Mathematical calculation of the duration of normal operation of an irreparable device, i.e. for which a MTBF is not possible. The product, expressed in hours, is an indication on the reliability of the device.

Mean Time to Failure: The average time between hardware breakdown or loss of service. This may be an empirical measurement or a calculation based on the MTTF of component parts.
