| Comments | First half of the measurements are completed, running about 3 months late. Pilot mid-cycle checks are complete. As of 10 November 2022 artefacts now in first laboratory for second half. Request of addition of USA to schedule received no objections so remaining schedule has been amended with lab approvals. Protocol version 6 will soon be issued with changes only to schedule and participant lists (no change to artefacts or measurement requirements). |
