Annotation of standard text IEC 61649-ed.2.0 :
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. La CEI 61649:2008 fournit des methodes pour analyser les donnees dune distribution de Weibull en utilisant les parametres continus tels que temps avant defaillance, nombre de cycles avant defaillance, contraintes mecaniques, etc. La presente norme est applicable des que des donnees sur des parametres cruciaux tels que temps avant defaillance, contraintes, etc. sont disponibles pour un echantillon aleatoire dentites fonctionnant dans des conditions dessais ou en service, afin destimer des mesures de performance de fiabilite de la population dont ces entites sont issues. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: le titre a ete raccourci et se lit maintenant comme "Analyse de Weibull"; et des methodes pour des solutions a la fois analytiques et graphiques ont ete ajoutees.
