	'''Burn-in''' is the process by which components of a system are exercised before being placed in service (and often, before the system being completely assembled from those components). This testing process will force certain failures to occur under supervised conditions so an understanding of load capacity of the product can be established.

This testing process will force certain failures to occur under supervised conditions so an understanding of load capacity of the product can be established.

	The intention is to detect those particular components that would fail as a result of the initial, high-failure rate portion of the [[bathtub curve]] of component [[Reliability engineering\|reliability]]. If the burn-in period is made sufficiently long (and, perhaps, artificially stressful), the system can then be trusted to be mostly free of further early failures once the burn-in process is complete.

	Theoretically, any weak components would fail during the "Burn In" time allowing those parts to be replaced. Replacing the weak components would prevent premature failure, infant mortality failure, or other latent defects.~~<ref name="aegis_ps_glossary"/>~~		Theoretically, any weak components would fail during the "Burn In" time allowing those parts to be replaced. Replacing the weak components would prevent premature failure, infant mortality failure, or other latent defects.

	When the equivalent lifetime of the stress is extended into the increasing part of the bathtub-like failure-rate curve, the effect of the burn-in is a reduction of [[product lifetime]]. In a mature production it is not easy to determine whether there is a decreasing failure rate. To determine the failure time distribution for a very low percentage of the production, one would have to destroy a very large number of devices. By stressing all devices for a certain burn-in time the devices with the highest failure rate fail first and can be taken out of the cohort. Thus by applying a burn-in, early in-use system failures can be avoided at the expense (tradeoff) of a reduced yield caused by the burn-in process.
