[′fāl·yər ‚rāt]
The probability of failure per unit of time of items in operation; sometimes estimated as a ratio of the number of failures to the accumulated operating time for the items.

Failure Rate


the index of dependability of a device that is not subject to repair. Most often it is used to define the dependability of the subassemblies of electronic and automatic systems. In numerical terms the failure rate is equal to the failure probability of the device during a time period beginning at a certain moment provided that no failure has occurred before.

Failure Rate


an index of the reliability of repairable tools and machines. The failure rate is defined as the average number of failures of the repairable device per unit of time and varies with time.
