IEC TC100 US TAG Rules and Guides

CTA is the U.S. National Committee (USNC) Technical Advisory Group (TAG) Administrator for the International Electrotechnical Commission (IEC) Technical Committee 100 (TC100), Audio, Video and Multimedia Systems and Equipment. The U.S. TAG provides the management for U.S. participation in TC100. It initiates New Proposals for nationally accepted Standards and Technical Reports and approves proposals and committee drafts submitted by Standards Developing Organizations or Consortia for consideration by TC100 as International Standards. The U.S. TAG also determines U.S. positions on IEC standards, technical reports, committee drafts, questionnaires, TC100 meeting agenda items (and allows delegate flexibility on them), and meeting reports. It assists with resolving comments on draft IEC standards. The U.S. TAG provides U.S. representation to TC100 meetings, designates heads and members of delegations, and ensures proper U.S. participation. The U.S. TAG identifies and establishes close liaison relationship with other U.S. TAGs in related areas. The TAG recommends the acceptance of Secretariats for IEC Technical Committees to the United States National Committee (USNC), and it makes recommendations to the USNC on TC100 meetings in the U.S. The U.S. TAG also recommends candidates for leadership and participation in IEC TC100 Technical Areas, working groups, project teams, and maintenance teams to the USNC.


Membership in the U.S. TAG is open to all US national interested parties who indicate that they are directly and/or materially affected by the activity of the TAG, after being informed concerning TAG working procedures and scope of activities.
