Welcome to the IEC TC57 Working Groups Collaboration Site!
Access to this site requires membership on a National Committee participating in the IEC TC57 Working Groups. UCA International Users Group hosts this site for the benefit of these groups. Working group members on this site can access information on other UCA sites, since a common site account is shared across all the sites.
UCAIug members can access draft standards and working documents from IEC TC57 Working Groups 10, 13, and 14, since UCAIug has Category D Liaison Organization status with the IEC.
These documents are made available to CIM Users Group members on the CIMug site, IEC TC57 WG Draft Documents section (click here to access).
