The Physikalisch-Technische Bundesanstalt (PTB), the National Metrology Institute of Germany, is developing new methods for the calibration of torque transducers with dynamic torque. In this case the traceability is based on the measurands of moment of inertia and angular acceleration. This contribution describes the experimental determination of the moment of inertia intrinsic to the standard device. For the measurement a torsional pendulum was realized and its oscillation was traced by the laser interferometric measurement system of the device.
