Hybrid Comparison: Calibration of 50 L neck type proving tank – volumetric method

Project Description:

The objective of this Hybrid Comparison (HC) is to ensure the evidence to Institute of Metrology of Bosnia and Herzegovina (IMBIH) to publish CMC for calibration of standard capacity measures – volumetric method.

The Hybrid Comparison will be conducted in accordance to "APMP Guideline for Using Hybrid Comparisons as CMC Evidence", 2023, when TS requires stability check provided by Applicant NMI.
The participants of HC are IMBIH (Applicant NMI), Directorate for Measures and Precious Metals, Serbia (issuing NMI) and TC-Flow Chair (independent Third Party).

Final Report 2026-03-31

The results of Hybrid Comparison with En score significantly lower than threshold demonstrate the IMBIH competence to calibrate volumetric vessels with volumetric method.
