scope:
The methods described in this document apply to failure modes and mechanisms whose failures exhibit a constant failure rate, e.g., an Arrhenius behavior characterized by an activation energy for failure. If data on the distributions of failure with time exist, these activation energies can be assumed from prior knowledge or failure analysis signatures. If the default activation energies are not known or can't be determined, an activation energy can be used as a default. Refer to JEP122 Activation Energies for Failure Mechanisms to obtain initial estimates.
The purpose of this method is to provide a reference to the way failure rates are calculated in FITs.

Methods for Calculating Failure Rates in Units of FITs
This standard establishes methods for calculating failure rates in units of FITs by using data in varying degrees of detail such that results can be obtained from almost any data set. The objective...
