• peer reviews of the QMS of COOMET NMIs/DIs (including the results of the peer reviews of the QMS of BelGIM (Belarus), NSC "Institute of Metrology" and SE "Ukrmetrteststandart" (Ukraine) and plans for conducting peer reviews of the QMS of DP NDI "Systema" (Ukraine) and KazStandard (Kazakhstan);
• preparation of a draft COOMET recommendation establishing special requirements (criteria) to NMIs and DIs in addition to ISO/IEC 17025:2017 etc.;
• holding of training events for COOMET technical experts on CMC review (in view of the new database KCDB 2.0) and on peer review of the QMS of COOMET NMIs/DIs.

Presidential Council members discussed the issues of appointing and extending the terms of office of the Chairs of a number of technical committees and subcommittees (final approval of all candidatures will take place at the COOMET Committee meeting in 2022) and reviewed the applications for giving the distinguished title "Honorary Metrologist of COOMET".

The issues of preparation for the 33^rd COOMET Committee meeting and a COOMET seminar on digital transformation in metrology (7 to 9 June 2020) were also discussed.
