| Comments | The protocol will be updated to reflect new time lines. The comparison is starting late due to shipping delays. New circulation schedule confirmed by participants - 11 Nov 2021. Due to delayes, the schedule had to be revised. Confirmed schedule of 12 Jan 2022 is being implemented. First leg of circulation completed. Current circulation as per AFRIMETS.AUV.V-K5_Schedule_(Ver-20-05-2022).pdf INTI completed measuerements. Artifacts in the process of beeing returned to NMISA, All participants completed measurements. Artefacts were returned to NMISA, pilot laboratory. |
