Infant mortality factor
Note: The steady state failure rate is equal to the failure rate of the system.
The number of failures that a product experiences during the first year of service after
turn-up may be greater than the number of subsequent annual steady state failures. This
is the early life or infant mortality period. The ratio of the first year failure rate to the
steady state failure rate is termed the infant mortality factor (IMF).
