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.


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.

The Rudolf-Martin-Ehrenurkunde is awarded annually by the DIN/VDI Standards Committee Acoustics, Noise Control and Vibration Engineering (NALS) for special achievements in standardisation. It is dedicated to the former Head of the Mechanics and Acoustics Division at PTB and Founding Chair of NALS Prof. Rudolf Martin. This year it returns to PTB in a way when it was awarded to Dr. Thomas Fedtke,...
