Mass and derived quantities


In the subject area "Mass and Derived Quantities", the activities are focused on the realization and dissemination of the mechanical units of mass, force, torque and pressure (also vacuum pressure) – based on the Units and Time Act, the Measures and Verification Act, and the European Measuring Instruments Directive. This subject area is highly oriented on industry, with a very great number of calibrations as well as tests for conformity assessment. To meet the current and future requirements of industry, science and research for exact measurements, the following tasks are performed:

  1. Advanced investigations for the practical realization and dissemination of the unit of mass, in particular for the time after the expected redefinition of the kilogram

  2. Setting up of standard machines for the measurement of large torques within the scope of the establishment of a Wind Energy Competence Centre; extension and further development of the standard machine for static forces from 1 N to 16.5 MN and torques from 1 mN•m to 5 MN•m; realization of standard machines for small forces in the range from 100 μN to 1 N; extension of the force standard machine to multi-components (force and torque); extension of the force standard facility for large forces up to 50 MN

  3. Realization or extension of the standard machines for dynamic forces and torques, among other things for sinusoidal forces up to 100 kN and pulsed forces up to 250 kN; further development of the standard machine for the traceable calibration of piezoelectric pressure transducers for dynamic pressures up to 800 MPa

  4. Ensuring the pressure scale up to 1.6 GPa; development of pressure primary standards with relative uncertainties smaller than 1 × 10–6 within the scope of the redefinition of the Boltzmann constant

  5. In vacuum metrology: Creation of measurement capabilities for dynamic pressures in low vacuum and for partial pressures in high vacuum.
