Mechanics and Acoustics

Division 1

Weight, force, velocity, loudness -€“ the mechanical and acoustic quantities are cared for by Division 1. Apart from basic research, testing within the scope of legal metrology is a main task.

Tasks

The Division carries out basic research in the field of mechanical and acoustical measurands. On the basis of the Units and Time Act, standards and standard measuring devices are developed with the aid of which the measurement scales for all relevant mechanical and acoustical measurands such as mass, force, torque, acceleration, flowrate of gases and liquids, sound and ultrasound pressure can be realized with maximum accuracy and disseminated, predominantly to DAkkS laboratories. The tasks of the Division also comprise type examinations and certifications of measuring instruments on the basis of national regulations - such as the Verification Act and the Verification Ordinance - of European Measuring Instruments Directives as well as international recommendations of the OIML. In addition, employees of the Division provide advice in all matters of relevant metrology, assess DAkkS and other calibration and test laboratories and cooperate in the respective national and international committees.

News

For the first time, torque measurement in nacelle test benches has been traced to the national standard. Common torque calibration standards only provide methods for static torque calibration. However, for torque measurement in nacelle test benches, calibration at varying rotational speeds is required. The findings and research will contribute to a reliable efficiency determination.
