The EURAMET Calibration Guide No. 21 "Guidelines on the Calibration of Standard Capacity Measures Using the Volumetric Method" has been developed in 2013. Since that time the measurement techniques have been improved and therefore it was decided in the EURAMET TC-Flow 2019 meeting that the guide should be revised and updated to the new EURAMET layout.
Final Report 2020-07-21
The revised version of Calibration Guide No. 21 "Guidelines on the Calibration of Standard Capacity Measures Using the Volumetric Method" (Version 2.0) was published on the EURAMET website in June 2020.
The current version reflects the actual practice applied in European National Metrology Institutes in terms of calibration procedures and calculation models for the calibration of Standard Capacity Measures (SCM) with the volumetric method. In particular, the changes to the previous version include: harmonisation with the new edition of ISO 8222 standard, widened measurement range of use, improvement of the criteria and the descriptions of general techniques, a better and more detailed description of the calibration procedure, addition of a new chapter on Neck scale calibration as well as technical details in different chapters and corresponding update of references.
