| Comments | Second cycle is almost complete after approximately 4 months lost due to customs issues. With participant agreement, Uzbekistan has been added to the remaining schedule, making 19 participants. No further additions will be considered. By October 2023, 15 laboratories will have completed measurements. It is now anticipated to have the draft report ready around May/June 2024 (which will be about 15 months later than the original schedule). |
