IEC 62427:2007

Railway applications - Compatibility between rolling stock and train detection systems

Describes a procedure for mutual acceptance of rolling stock to run over specific routes. Describes the methods of measurement of interference currents, the methods of measurement of the susceptibility of train detection systems, the characterisation of traction power supplies and the procedure for acceptance. The result of the acceptance procedure is a structured justification document referred to as a "compatibility case".

Applications ferroviaires - Compatibilité entre matériel roulant et systèmes de détection de train

Décrit une procédure d'acceptation mutuelle des matériels roulants sur un itinéraire donné. Décrit les méthodes de mesure des courants d'interférence, les méthodes de mesure de la susceptibilité des systèmes de détection de train, la caractérisation des alimentations de traction ainsi que la procédure d'acceptation. Le résultat de cette procédure d'acceptation est un document de justification structuré appelé "dossier de compatibilité".

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use
