Scope
The methods described in this document apply to failure modes and mechanisms whose failures
exhibit a constant failure rate, e.=., 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 enersy can be used as a default. Refer to
JEP 122 Activation Energies for Failure Mechanisms to obtain initial estimates.
