TC 1.2 Meeting September 2021 TC 1.2 Meeting September 2021 TC 1.2 Meeting September 2021 TC 1.2 Meeting September 2021 TC 1.2 Meeting September 2021

The 16th online meeting of COOMET TC 1.2 "Acoustics, Ultrasound, Vibration" was held on 29 September 2021. Representatives of 5 COOMET member countries (Belarus, China, Russia, Turkey, Ukraine) took part in the meeting.


The progress in implementation of the current projects within TC 1.2 and other issues, provided for in the agenda were discussed: proposals to the COOMET Program of Comparisons; issues on the implementation of the CIPM MRA, activities under the COOMET Development Program for 2020-2022 and Plan for Cooperation between COOMET and EURAMET within the TC, as well as organizational issues (update of the Regulation on the TC, changes in the membership of the TC).


The main adopted decisions:

  • to continue work on the current COOMET comparisons under the following COOMET projects: 706/RU/16 "Pilot comparison of longitudinal ultrasonic wave propagation velocity in solid media", 757/RU/18 "Comparisons of national measurement standards of the sound pressure units in air in the infrasound frequency range from 0.1 to 100 Hz" (COOMET.AUV.A-S3), ), 786/RU/19 "Comparisons of the results of amplitude-phase calibrations of hydrophones in the frequency range from 10 kHz to 500 kHz", 790/TR/19 "Supplementary comparison on calibration of sound calibrators", 846/RU/21 "Regional key comparisons in the field of ultrasound power measurement in water";
  • to consider it appropriate to conduct new COOMET comparisons (comparisons of calibrations of tone audiometers, comparisons of calibrations of ear simulators and calibrations of mechanical couplers, comparisons of calibrations of reference microphones in elaboration of key comparisons CCAUV.A-K6, comparisons in the field of vibration in elaboration of key comparisons CCAUV.V-K5, comparisons of measurement standards of vibration in the low-frequency region);
  • to request TC members to prepare proposals on development of model calibration procedures to assist CEEMS and  a list of issues to be addressed under COOMET project 825/BY/21 "Development of a COOMET concept for digitalization in metrology";
  • to request the NMIs, represented in the TC, to elaborate on appointing authorized representatives, whose tasks will include preparation and review of CMCs under the KCDB 2.0 platform etc.


The next COOMET TC 1.2 meeting is scheduled for September 2022.

Owing to the uncertain situation related to the Covid-19 pandemic, the venue of the meeting will be specified in a due course.
