Anotation

IEC TR 63162:2025, which is a Technical Specification, provides failure rates at reference conditions for electric components, considering reference conditions defined in IEC 61709. Reference conditions are useful since they provide a known standard basis from which failure rates can be modified to account for differences in environment from the environments taken as reference conditions. To perform reliability prediction, which is described in IEC 61709:2017, Annex C, failure rates, together with assumptions and limitations, are used. IEC 61709 does not provide failure rates for components, but only provides models that allow failure rates obtained by other means to be converted from one operating condition to another operating condition. This document provides generic failure rates considering those contained in the list of selected sources, calculated at reference conditions, as defined in IEC 61709. In fact, although models are different, calculated values at reference conditions do not appear to be so different, hence allowing a consistent converging process. See also IEC 61709:2017, 4.6. Each user can easily calculate failure rates at any condition using IEC 61709.
