CIPM MRA PARTICIPANTS

The KCDB - the BIPM key comparison database – supports the CIPM MRA. The KCDB contains information on the internationally recognized Calibration and Measurement Capabilities (CMCs) for services available from the participating institutes, and the key and supplementary comparisons supporting these CMCs.

All data listed in the KCDB have been reviewed and approved within the CIPM Mutual Recognition Arrangement

Comments	The circulation of the travelling standard restarted in September 2022 and was planned to end in April 2024, but unforseen problems in the end of the circulation caused a delay. The travelling standard was returned to the Pilot laboratory NIM in April 2025 and the final measurements were finalized in June 2025. The ananlyzis of the results and preparation of the Draft A report will be made by NPL.
