The most recent results issued from the continuous key comparison BIPM.QM-K2.b have been published in the KCDB, including the results obtained with E+E Elektronik, Austria in May 2026. This comparison underpins the capabilities of participants to value assign the amount fraction of CO₂ in air with a method that ensures traceability of the measurements to the SI.

The results of the key comparison APMP.EM.RF-K8.CL linked to those of CCEM.RF-K8.CL, have recently been published in the KCDB. This is a comparison on power in 50 ohm coaxial lines, coordinated by the National Metrology Institute of Japan (NMIJ), with participants from 11 state economies.

The results of the key comparison APMP.L-K3.n01 have been published in the KCDB. This is a comparison of calibration of angle gauge blocks, coordinated by the National Institute of Metrology (NIMT), Thailand, with participants from 10 state economies.

The Final report of the supplementary comparison EURAMET.L-S2.2.n01 has been published in the KCDB. This is a comparison on gauge block calibration by mechanical comparison, piloted by the Central Office of Metrology (AS METROSERT), Estonia in which 11 state economies participated.
