Information about the International Comparisons DatabaseThe International Comparisons Database (ICDB) provides access to results of comparisons of
National Metrology Institute (NMI) measurements and standards. The ICDB serves the U.S. and the
Inter-American System of Metrology (SIM)
with information based on Appendices B and D of the Comité International des Poids et Mesures (CIPM)
Mutual Recognition Arrangement (MRA).
The official source of the data is The BIPM key comparison database.
The National Institute of Standards and Technology (NIST) signed the CIPM MRA at a meeting of directors of NMIs on
October 14, 1999 in Paris during the 21st quadrennial meeting of the General Conference on Weights and Measures.
Files related to the measurement and calibration capabilities of the NMIs, referred to as Appendix C in the CIPM MRA,
can now be downloaded from this site. Eventually, the records in these files will be added to the database so that users
can search for specific NMI capabilities.
