IEC 61709:2011 PDF (Not Available)

IEC 61709:2011 is a standard that provides guidance on how to use failure rate data to predict the reliability of electric components in equipment. It defines reference conditions, which are typical values of stresses experienced by components in most applications. These reference conditions serve as the basis for calculating failure rates under any operating conditions by applying stress models that consider the actual conditions. The standard also offers direction on how to build a component failure data database to obtain failure rates that can be used in conjunction with the provided stress models. This edition of the standard introduces updates and additions, including new component types and revised models for existing component types. Additionally, it includes annexes on reliability prediction, sources of failure rate data, and component classification information.
