The Interamerican Metrology System (SIM) resulted from a broad agreement among national metrology organizations from all 34 member statesof the Organization of American States (OAS). Created to promote international cooperation in metrology, SIM is committed to the implementationof a Global Measurement System within the Americas. 

SIM Program in Chemical Metrology

The Chemical Metrology Working Group (CMWG) is one of 13 SIM Technical Working Groups. In order to most effectively address the uniqueneeds of all 34 countries within SIM, whose capabilities in chemical metrology span a very broad range, we have initially focused SIM ChemicalMetrology Working Group activities on training and capability assessment rather than participation in MRA-driven Key and Supplemental Comparisons:

This is being accomplished through:

  • Outreach and Chemical Metrology Awareness Activities within the ANDIMET CAMET, CARIMET and SURAMET Subregions,
  • Chemical Measurement Proficiency Assessment Comparison Studies and follow-up activities
  • Training in CMC preparation and review.

Long-Term SIM CMWG Goal:  Improved capabilities in chemical metrology and increased participation in CCQM and CIPM MRA-related activities.
