Annotation of standard text IEC 61373-ed.2.0 :

IEC 61373:2010 specifies the requirements for testing items of equipment intended for use on railway vehicles which are subsequently subjected to vibrations and shock owing to the nature of railway operational environment. To gain assurance that the quality of the equipment is acceptable, it has to withstand tests of reasonable duration that simulate the service conditions seen throughout its expected life. The main technical changes with regard to the previous edition are as follows: - change of the method to calculate the acceleration ratio; - addition of the notion of partially certified against this standard; - addition of guidance for calculating the functional RMS value from service data or the RMS value from ASD levels. La CEI 61373:2010 specifie les exigences dessai des materiels destines a etre utilises sur les vehicules ferroviaires soumis a des vibrations et a des chocs dus a la nature de lenvironnement dexploitation ferroviaire. Pour sassurer que la qualite dun materiel est acceptable, celui-ci doit resister a des essais dune duree raisonnable qui simulent les conditions de service auxquelles il est expose tout au long de sa vie. Les principaux changements techniques par rapport a ledition precedente sont les suivants: - changement de la methode pour calculer le taux dacceleration; - ajout de la notion de certification partielle par rapport a la norme; - ajout de recommandations pour le calcul de la valeur efficace fonctionnelle a partir des donnees de service, ou de la valeur efficace a partir des niveaux dASD.
