• discussion of proposals on new comparisons under the auspices of TC 1.7;
• about the resolutions of the Joint Committee for Measurement Standards and discussion of (1) CEEMS proposals on the organization and conduct of comparisons and (2) prospects for creating COOMET courses on the BIPM e-learning platform on the issues of photometry and radiometry;
•  about intra- and interregional CMC review, update of the list of technical experts on CMC review and peer review of the QMS of COOMET NMIs/DIs.
