Yelizaveta TARASENKO Director of the Research and Production Institute for Measurement of the Composition, Properties and Quantity of Substances and Materials and Assessing the Conformity of Measuring Instruments (Institute № 2) is a Member of Inorganic analysis working group (CCQM-IAWG) and PROFICIENCY TESTING SCHEME OR ROUND FOR YOUR LABORATORY (EPTIS).

Institute represents Ukraine in the international measurement community as:

• a full member in Eurachem (a network of organizations in Europe focusing for analytical chemistry and quality). Eurachem's technical activity is carried out by its various working groups (WGs). Our specialists currently take an active part in the following WGs: Measurement Uncertainty and Traceability and Qualitative Analysis;
• a representative of the institute is an observer in the EURAMET Technical Committee for Metrology in Chemistry (TC - MC), it’s a Joint EURAMET - Eurachem TC.  The Institute as the Secretariat of the TC for Standardization TC 122 "Analysis of gases, liquids and solids". 
  Participates in the in the work of ISO TCs for Metrology in Chemistry.

Where Ukraine is P - member:
