ADA136design lifeLEVEL(MIN,TYP,MAX) OF REAL_MEASURE_TYPE

duration for which specified performance characteristics of an item are granted by the manufacturer

ADA141useful life of an itemLEVEL(MIN,TYP,MAX) OF REAL_MEASURE_TYPE

time interval, from first use until user requirements are no longer met, due to economics of operation and maintenance, or obsolescence

ADA142early life failure periodLEVEL(MIN,TYP) OF REAL_MEASURE_TYPE

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

ADA143constant failure intensity periodLEVEL(MIN,TYP) OF REAL_MEASURE_TYPE

time interval, in the life of a repairable item, during which its failure intensity is considered to be constant

ADA144constant failure rate periodLEVEL(MIN,TYP) OF REAL_MEASURE_TYPE

time interval, in the life of a non-repairable item, during which its failure rate is considered to be constant

ADA145wear-out failure periodLEVEL(MIN,TYP) OF REAL_MEASURE_TYPE

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

ADA234overall lifetimeLEVEL(MIN) OF INT_MEASURE_TYPE

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

ADA236electrical durabilityLEVEL(MIN) OF INT_MEASURE_TYPE

guaranteed number of on-load operating cycles which can be effected without repair at defined normal operation (syn.: service) conditions
