NIST OWM is made up of more than 30 experts that are weights and measures coordinators, physical scientists and engineers, laboratory and scientific metrologists, national and international standards experts, and training and administrative professionals.
Our staff serve as technical advisors and secretariats to SDOs and working groups; investigate new technologies and develop inspection and calibration procedures; progress and maintain NIST Handbooks, guidance documents, test and examination operation procedures and other documentary standards; operate the laboratory metrology program to ensure SI traceability and quality measurement results; and develop and provide in-person, virtual and hybrid training for stakeholders and the U.S. metric and weights and measures communities at-large.
