Annotation of standard text IEC 61810-2-ed.3.0 :
IEC 61810-2:2017 covers test conditions and provisions for the evaluation of endurance tests using appropriate statistical methods to obtain reliability characteristics for relays. This document applies to electromechanical elementary relays considered as non-repaired items (i.e. items which are not repaired after failure). This document does not cover procedures for electromechanical elementary relays where enhanced requirements for the verification of reliability apply. This edition includes the following significant technical changes with respect to the previous edition: - not only graphical but also numerical methods are added; - reduction of number of samples in specified cases; - new subclauses of confidence intervals are added; - the WeiBayes approach is added to facilitate compliance tests (routine test) with lower effort; - annexes have been restructured into an Annex A for data analysis (normative) and Annex B (informative) where various examples of the data analysis are given; - the former Annex C has been incorporated into the modified Annex B; - a new Annex C replaces the old Annex D. L’IEC 61810-2:2017 couvre les conditions d’essai et les dispositions pour l’evaluation des essais d’endurance utilisant les methodes statistiques appropriees pour obtenir les caracteristiques de fiabilite pour les relais. Le present document s’applique aux relais electromecaniques elementaires consideres comme des entites non reparees (c’est-a-dire des entites qui ne sont pas reparees apres defaillance). Le present document ne couvre pas les procedures d’essai relatives aux relais electromecaniques elementaires lorsque des exigences renforcees pour la verification de la fiabilite s’appliquent. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - ajout de methodes non seulement graphiques mais aussi numeriques; - reduction du nombre d’echantillons dans des cas specifies; - ajout de nouveaux paragraphes relatifs aux intervalles de confiance; - ajout de l’approche WeiBayes pour permettre une realisation efficiente des essais de conformite (essai individuel de serie); - reorganisation des annexes en Annexe A (normative), dediee a l’analyse des donnees et en Annexe B (informative), dans laquelle plusieurs exemples d’analyse des donnees sont presentes; - insertion de l’ancienne Annexe C dans l’Annexe B modifiee; - remplacement de l’ancienne Annexe D par une nouvelle Annexe C.
