EN IEC 61375-2-8:2021

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.

Železniške elektronske naprave - Komunikacijsko omrežje vlaka (TCN) - 2-8. del: Preskus skladnosti TCN

Ta del standarda IEC 61375 se uporablja za vso opremo in naprave, ki se uporabljajo v skladu s standardi IEC 61375-2-3:2015, IEC 61375-2-5:2014 in IEC 61375-3-4:2014, tj. zajema postopke, ki jih je treba uporabljati za tako opremo in naprave v primeru dokazovanja skladnosti. Uporaba tega dokumenta za izvedbo komunikacijskega omrežja vlaka (TCN) omogoča posamezno preverjanje skladnosti same izvedbe in je pogoj za nadaljnje preverjanje interoperabilnosti med različnimi izvedbami komunikacijskega omrežja vlaka.
