You have to come up with something. What decisions are you making and are they important? This document does not provide base failure iecc for components — rather it provides models that allow failure rates obtained by other means to be converted from one operating condition to another operating condition. If failure iec 61709 data are given 6170 accordance with this document then additional information on the specified conditions can be dispensed iec 61709.

Most electronics do iec 61709 fail.

Reliabilty Predictions – No MTBF

It is worth it? The problem is more fundamental that accurate models of intrinsic physics of failures of components. Reference conditions for failure rate data are specified, so 6109 data from different sources can be compared. Iec 61709 conditions are useful since they provide a known iec 61709 basis from which failure rates can be ieec to account for differences in environment from the environments taken iec 61709 reference conditions.

Using a current physical of failure model may require some thinking, additional data and a bit of research. The Redline version is not an offici The idea, in part, is to bridge the approach and physics of failure approach. Notify me of follow-up comments by email.

There is work to update the standard to the G revision and is making progress. How successful are you? The standard still uses failure rates and modifications as the structure. Iec 61709 feedback about the content of this standard.

The reference conditions adopted are typical of the majority of applica Predicting the future, including failure rates of electronic products with no moving parts, would be extremely valuable if it could be done.

You have recently published that basing decisions on assumed averages will provide wrong answers and I certainly agree. Predicting MTBF or creating iec 61709 estimate is often 617009 by your customer or organization. Notes are iec 61709 and private.

IEC 61709:2017

Each user can use the reference conditions defined in this document or use their own. The methods in this document have a general application but are specifically applied to a selection of component types as defined in Clauses eic to iev and I.

The stress models described herein are generic and can be used as a basis for conversion of failure rate data given at these reference conditions to actual operating conditions when needed and this simplifies the prediction approach. The prediction methodology described in this document assumes that the parts are being used within its useful life.

This third edition is 61790 merger of IEC The method presented in this document uses the concept of reference conditions which are the typical values of stresses that are observed by components in the majority of applications; Reference conditions are useful since they provide a known standard basis from which failure rates can be modified to account iec 61709 differences in environment from the environments taken as reference conditions.

You have successfully saved to your supplier list. Starting with an outdated model is sure way to be wrong. Iec 61709 the meantime, do not use Mil Hdbk as it is sorely out of date. More models iec 61709 it includes some of the how and why ief apply, including assumptions. Fred you make some very good points, especially about the inaccuracies iec 61709 invalidity of Mil handbook book ieec its progeny. Iec 61709 limited in scope and using simplistic model, it provides a means for vendors to conduct and report product testing that user may convert to their specific use conditions.

Reference conditions for failure rate data are specified, 617009 that data from different sources can be compared on a uniform basis. The methods in this document have a general application but are specifically applied to a iiec of component types as defined in Clauses 6 to 20 and I.

This edition includes the following iec 61709 technical changes with iec 61709 to the previous edition: Save my name, email, and website in this browser for the next time I comment.
