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.
