Important Updates to IEC 61850 Conformance Testing

by Joe Stevens | May 17, 2018

The UCA is implementing changes to the IEC 61850 certification testing program in order to follow IEC requirements that only one revision of a standard can be valid at one time. Edition 1 was officially withdrawn by the IEC in December 2012 when Edition 2 became the current revision of the IEC 61850 standard. The UCA has therefore decided to phase out the issuing of Edition 1 only certificates and transition to Edition 2 conformance test certificates. The new Edition 2 conformance tests will include an option for certifying backward compatibility for Edition 1. This will allow new test certificates to cover both Edition 1 and 2 as required by utilities that install new equipment into existing Edition 1 systems or mixed systems (containing Ed. 1 and 2 devices).

The end-of-life date for Edition 1 conformance testing and certification is targeted for December 31, 2020. However, the actual date may change depending on when updates to Edition 2 conformance tests are published with procedures for testing Edition 1 backward compatibility. Please read the official press release from the UCA for many more details.
