What is Bathtub curve?
A curve showing how the failure rate changes over time. It consists of the early-failure, random-failure and wear-out periods and is shaped like a bathtub.
Field: Reliability
Bathtub curve in the explanations
The bathtub curve consists of the early failure period, when the failure rate is high at the start of use; the random failure period, when the failure rate is low and nearly constant; and the wear-out failure period, when the failure rate rises due to degradation.
Which correctly lists the three periods that make up the ba…Its purpose is to reduce, before shipment, the failures that would occur in the early-failure period of the bathtub curve.
Which correctly describes the purpose of burn-in?
