Physical Measurement Laboratory /Quantum Measurement Division

Mass and Force Group

The Group performs the research and development needed to provide traceability, measurement solutions, and calibration services to the US industry, government, and academia in the areas of mass, force, and the dynamic mechanical quantities of acoustics, force, and vibration.

The group also

  • Represents the interests of the US in the national, regional, and international metrology communities, through participation and/or leadership in consultative committees, working groups, and standards organizations to guarantee US competitiveness and the equivalence of standards worldwide.
  • Carries out research and development and provides technical support in legal metrology, measurement science, instrumentation design, development, and testing to develop new physical measurement services, new realization of the units, new transfer standards, new methods and data, and custom tests to improve NIST capabilities in providing traceability and leadership to meet the needs and demands of U.S. industry, government, and the scientific community.
