The force and torque standards group's primary mission is to establish, improve, and maintain the national standards of force and torque, which have been developed by NMIJ and NRLM (the former NMIJ). We also retain the international equality of force and torque units with other countries. Finally, we steadfastly disseminate the national standards to the industry.

We establish and strengthen the traceability of measurement in the force field (from force standard machines to force measuring instruments and then, force testing machines), and in the torque field (from torque standard machines to torque measuring devices and then, torque testing machines). We investigate to solve the problems concerned with the traceability of measurements, such as the development of precise and stable force and torque transducers, and the development of effective calibration and measurement techniques of force and torque. In addition, we develop force and torque standards, realizing them more precisely and stably using different principles. Furthermore, we cooperate with the industry to solve technical or social problems through joint research and technical consulting.

1. Developing and improving in national force standard: We are developing tuning-fork type force transducers with good long-term stability in sensitivity and effective comparison methods suitable to calibration and measurement capabilities.

2. Developing and improving in national torque standard: We are studying on the expansion of the calibration range of national torque standard, and developing high accuracy torque transducers.

3. Research and development for torque measurement technique using electromagnetic force: We have been studying a torque standard machine based on a torque generation method using electromagnetic force, and a measurement method for microscopic torque.

4. Research and development for Force measurement technique using electromagnetic force: We are studying the precise microforce generating technique and measurement technique by using electromagnetic force referring to the principle of the Kibble balance experiment.
