Weibull analysis

IEC 61649:2008 provides methods for analysing data from a Weibull distribution using continuous parameters such as time to failure, cycles to failure, mechanical stress, etc. This standard is applicable whenever data on strength parameters, e.g. times to failure, cycles, stress, etc. are available for a random sample of items operating under test conditions or in-service, for the purpose of estimating measures of reliability performance of the population from which these items were drawn. The main changes with respect to the previous edition are as follows: the title has been shortened and simplified to read 'Weibull analysis'; and provision of methods for both analytical and graphical solutions have been added.

Weibull-Analyse

Analyse de Weibull

La CEI 61649:2008 fournit des méthodes pour analyser les données d'une distribution de Weibull en utilisant les paramètres continus tels que temps avant défaillance, nombre de cycles avant défaillance, contraintes mécaniques, etc. La présente norme est applicable dès que des données sur des paramètres cruciaux tels que temps avant défaillance, contraintes, etc. sont disponibles pour un échantillon aléatoire d'entités fonctionnant dans des conditions d'essais ou en service, afin d'estimer des mesures de performance de fiabilité de la population dont ces entités sont issues. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: le titre a été raccourci et se lit maintenant comme 'Analyse de Weibull'; et des méthodes pour des solutions à la fois analytiques et graphiques ont été ajoutées.
