Electronic railway equipment - Train communication network (TCN) - Part 2-8: TCN conformance test

This part of IEC 61375 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.

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.
