International Laboratory Comparisons

As the U.S. National Metrology Institute (NMI) for chemical measurements, the Chemical Sciences Division of NIST cooperates in international laboratory comparisons with other NMIs and Designated Institutes (DIs) through International Committee of Weights and Measures (CIPM)-based engagements. This includes activities within the Consultative Committee for Amount of Substance – Metrology in Chemistry and Biology (CCQM) and the Inter-American Metrology System (SIM) as the Regional Metrology Organization (RMO) for the Americas. Additionally, CSD maintains numerous strategic bi- and multi-lateral collaborations with institutes and other standards-based organizations around the world.  [International Comparisons for Chemistry]
