duration for which specified performance characteristics of an item are granted by the manufacturer
time interval, from first use until user requirements are no longer met, due to economics of operation and maintenance, or obsolescence
time interval of early life during which the instantaneous failure intensity of a repairable item, or the instantaneous failure rate of a non-repairable item, decreases significantly with time
time interval, in the life of a repairable item, during which its failure intensity is considered to be constant
time interval, in the life of a non-repairable item, during which its failure rate is considered to be constant
time interval in the life of an item for which the instantaneous failure intensity of a repairable item, or the instantaneous failure rate of a non-repairable item, increases significantly with time
lifetime of the item which should not be exceeded in order to maintain the validity of the estimated failure rates due to random hardware failures, starting at date of production
date at which the item was produced, being ready for use
guaranteed number of on-load operating cycles which can be effected without repair at defined normal operation (syn.: service) conditions
