Research Activities

The Dimensional Metrology Group (683.01) conducts research to lower the uncertainty of our calibrations, to develop new measurement technology, and to advance national and international standards. The group actively collaborates with universities, other national laboratories, and industrial partners.

Current Research Activities

Fundamental aspects of measurement uncertainty Pioneer research in traceability and uncertainty Research in support of ASME and ISO documents as well as the Guide to the Expression of Uncertainty in Measurement (GUM) Papers: Measurement Uncertainty
