It further decided that the title be changed to: Joint IEC-CIGRE coordination group to provide guidance to IEC and CIGRE in the development of UHV standardization. While limiting the size of the group, the number of IEC members be increased to 11 and invites NCs who have already submitted nominations to limit them to only one and submit to Central Office by The SMB appointed Mr. Hisatoshi Ikeda as convener of the joint IEC-CIGRE group. The SMB invited CIGRE to concur. 2nd International Symposium on Standards for UHV Transmission , New Delhi
