First key comparison of Josephson voltage standards for AC voltage completed by BIPM and PTB — a major step for global traceability in electrical measurements. The third Consensus Value of the kilogram is now in effect since March 1, 2026.

Updated kilogram Consensus Value: −12 μg relative to the IPK, uncertainty 20 μg. All mass calibration laboratories must update their traceability statements. NIST hosted an informational webinar on April 8.

GAS Analysis 2026 is shaping up as a key event for NMIs, instrument manufacturers, and advanced analyser users. The DCC2GO initiative continues building digital calibration certificate capabilities across European metrology institutes.

New CMC entry published for Uzbekistan in AC current measurements (via COOMET). Final report of EURAMET.TF-S1 supplementary comparison on time interval released — 24 participants, piloted by GUM Poland.

New findings in gas pressure metrology at PTB reveal a novel physical phenomenon that will help reduce measurement uncertainty — results published in 2026.

The metrology community honors the memory of Dr. Zafar Taqvi (†February 2026), a respected leader in robotics measurement and longtime Chair of TC17. Preparations for the IMEKO World Congress continue.
