A subgroup has been set up with members from CMI, GUM and PTB.
Activities will be synchronised to a planned CCEM comparison with a similar scope which will be organised by NRC, Canada.
Final Report 2012-09-29
Project 637 was postponed until a CCEM key comparison is carried out. Since the CCEM comparison has not yet started, the TC-EM decided to close project 637 and to start a new project once the results of the CCEM comparison are available.
