IEC 62427-ed.2.0

Annotation of standard text IEC 62427-ed.2.0 :

IEC 62427:2024 describes a process to demonstrate compatibility between rolling stock (RST) and train detection systems (TDS). It describes the characterization of train detection systems, rolling stock and traction power supply systems. It is worth noting that the demonstration of technical compatibility between the rolling stock and infrastructure with respect to physical dimensions is not detailed in this document. This document is not generally applicable to those combinations of rolling stock, traction power supply and train detection system which were accepted as compatible prior to the publication of this document. However, as far as is reasonably practicable, this document can be applied to modifications of rolling stock, traction power supply or train detection systems which can affect compatibility. The detailed process can be used where no rules and processes for compatibility are established. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) generic compatibility process, which is broken into a two-stage process depending on whether there are established compatibility limits or not; b) rules for characterization of train detection systems; c) rules for characterization of rolling stock; d) rules for characterization of the power system; e) informative references are provided in notes to established CENELEC standards for compatibility; f) terminology is updated. IEC 62427:2024 Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) procedure de compatibilite generale a deux niveaux (selon que les limites de compatibilite etablies sont respectees ou non); b) regles de caracterisation des systemes de detection de train ; c) regles de caracterisation du materiel roulant ; d) regles de caracterisation de lalimentation de traction ; e) ajout de references normatives aux normes CENELEC etablies dans les notes pour la compatibilite ; f) mise a jour de la terminologie. La presente version bilingue (2025-11) correspond a la version anglaise monolingue publiee en 2024-12. Le present document decrit une procedure qui permet de demontrer la compatibilite entre le materiel roulant (MR) et les systemes de detection de train (SDT). Il fournit egalement des informations sur la caracterisation des systemes de detection de train, du materiel roulant et des alimentations de traction. Il est a noter que le present document ne couvre pas la demonstration de compatibilite technique entre le materiel roulant et linfrastructure en termes de dimensions physiques. Le present document ne sapplique generalement pas aux ensembles materiels roulants, alimentations de traction et systemes de detection de train qui ont deja ete reconnus compatibles avant la publication du present document. Toutefois, le present document peut etre applique, dans des limites raisonnables, aux modifications du materiel roulant, de lalimentation de traction et des systemes de detection de train qui sont susceptibles de compromettre la compatibilite. La procedure decrite dans le present document peut etre utilisee lorsquaucune regle ni procedure de compatibilite nont ete definies. Cette seconde edition annule et remplace la premiere edition parue en 2007. Cette edition constitue une revision technique.
