(Main)Electronic railway equipment - Train communication network (TCN) - Part 2-8: TCN conformance test
Electronic railway equipment - Train communication network (TCN) - Part 2-8: TCN conformance test
IEC 61375-2-8:2021 applies to all equipment and devices implemented according to IEC 61375-2-3:2015, IEC 61375-2-5:2014 and IEC 61375-3-4:2014, i.e. it covers the procedures to be applied to such equipment and devices when the conformance should be proven. The applicability of this document to a TCN implementation allows for individual conformance checking of the implementation itself, and is a pre-requisite for further interoperability checking between different TCN implementations.
Matériel électronique ferroviaire - Réseau embarqué de train (TCN) - Partie 2-8: Essai de conformité TCN
IEC 61375-2-8:2021 s'applique à l'ensemble des équipements et dispositifs mis en œuvre conformément à l'IEC 61375-2-3:2015, l'IEC 61375-2-5:2014 et l'IEC 61375-3-4:2014, c'est-à-dire qu'elle couvre les modes opératoires à appliquer à ces équipements et dispositifs dont il convient de démontrer la conformité.
