Welcome to the IEC TC57 Working Groups Collaboration Site!
Access to this site requires membership on a National Committee participating in the IEC TC57 WGs residing here. The UCAIug is a Category D Liaison Organization with IECTC57 WG10 and WG13. This Liaison agreement provides UCAIug members access to draft standards and working documents form these two WGs. The documents that are available are kept in the Document libraries listed in the "left quick launch bar" on this page.
