Railway applications - Electric equipment for rolling stock - Part 1: General service conditions and general rules
IEC 60077-1:2017 is now available as IEC 60077-1:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60077-1:2017 specifies the general service conditions and requirements for all electric equipment installed in power circuits, auxiliary circuits, control and indicating circuits etc., on railway rolling stock. The purpose of this document is to harmonize as far as practicable all rules and requirements of a general nature applicable to electric equipment for rolling stock. This new edition includes the following main technical changes with regard to the previous edition:
- descriptions regarding insulation coordination, environmental conditions and those of current return and protective bonding are deleted and replaced by references to IEC 62497‑1, IEC 62498-1 and IEC 61991;
- classification of equipment type is introduced;
- temperature limits and temperature rise tests are reviewed.

IEC 60077-1:2017 est disponible sous forme de IEC 60077-1:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L’IEC 60077-1:2017 spécifie les conditions générales de service et les exigences pour l'ensemble de l'équipement électrique installé dans les circuits de puissance, les circuits auxiliaires, les circuits de commande, les circuits de signalisation et de surveillance, etc., sur le matériel roulant ferroviaire. Le présent document a pour objet d’harmoniser dans la mesure du possible l’ensemble des règles et des exigences de caractère général applicables aux équipements électriques du matériel roulant. Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- suppression et remplacement des descriptions concernant la coordination de l’isolement, les conditions d’environnement et celles du retour de courant et de la mise à la masse par des références à l'IEC 62497-1, l'IEC 62498-1 et l'IEC 61991;
- introduction d’une classification de type d’équipement;
- révision des températures limites et des essais d'échauffement.
