IEC 61375-2:2007

Electric railway equipment - Train bus - Part 2: Train communication network conformance testing

Applies to all equipment and devices implemented according to IEC 61375-1, that is covers the procedures to be applied to such equipment and devices when the conformance should be proven. The applicability of this standard 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.
