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.
Researchers at the National Institute of Standards and Technology (NIST) have designed and built an optical device that could set a new standard for measuring
Mechanical engineers at the National Institute of Standards and Technology (NIST) have just finished calibrating several dozen large metal masses, which will be
Researchers at the National Institute of Standards and Technology (NIST) have conducted the first demonstration of a faster and more accurate way to calibrate
NIST provides calibration services for force-measuring instruments by applying known forces, compression, tension or both, to the elastic transducer and
The NIST Mass and Force Group disseminates the unit of mass, the kilogram, to the US measurement system through calibrations of customer weights and weight sets
The Dynamic Mechanical Metrology Project develops methods to provide accuracy in, and provides calibration services for, acoustic, vibration, acceleration, and

We demonstrate a microfabricated optomechanical accelerometer that is capable of percent-level accuracy without external calibration. To achieve this capability
We simulate the effect of gimbal-alignment errors and rotational step-size errors on measurements of the sensitivity matrix and intrinsic properties of a
