Title Electric components - Reliability - Reference conditions for failure rates and stress models for conversion
Project Number 22543
Abstract/Scope IEC 61709:2011 gives guidance on how failure rate data can be employed for reliability prediction of electric components in equipment. Reference conditions are numerical values of stresses that are typically observed by components in the majority of applications. Reference conditions are useful since they are the basis of the calculation of failure rate under any conditions by the application of stress models that take into account the actual operating conditions. This standard also gives guidance on how a database of component failure data can be constructed to provide failure rates that can be used with the included stress models. This edition includes the following significant technical changes with respect to the previous edition: - the addition of a number of component types and the updating of models for a large number of component types; - the addition of annexes on reliability prediction, sources of failure rate data and component classification information.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
