CIE Technical Committees:

  • The technical committees are the basis of the success and activity of the CIE. They consist of experts from around the world who develop reports, recommendations, and standards based on scientific knowledge.
  • All member bodies may provide input by appointing a TC member to a given committee. Consult the Division web sites for lists of currently active committees.
