All previously published reports remain available in the Metrologia Technical Supplement and all reports continue to be accessible via the BIPM’s Key Comparison Database (KCDB).
Hosting the new CIPM MRA Comparison Reports to bipm.org will:
- provide direct and central access through the BIPM’s own platform,
- ensure faster updates and publication workflows, and
- enhance discoverability and usability alongside other CIPM MRA resources.
We encourage the international metrology community to update bookmarks and begin accessing new Comparison Reports directly via bipm.org.
What are the CIPM MRA Comparison Reports?
The CIPM MRA Comparison Reports are formal reports presenting the results of key and supplementary comparisons conducted under the CIPM Mutual Recognition Arrangement (CIPM MRA). They provide the technical details that underpin the internationally recognized Calibration and Measurement Capabilities (CMCs) published in the BIPM Key Comparison Database (KCDB).
These documents were previously published in the Metrologia Technical Supplement — a section of the journal Metrologia.
