This year, EURAMET's Technical Committee for Mass and Related Quantities (TC-M) published a new guide on the "Calibration of Automatic Weighing Instruments’ (No. 26, Version 1.0), which is available to download for free. This is the first internationally harmonized document of its kind.
Automatic catchweighing instruments (or “catchweighers”) are a type of automatic weighing instrument (AWI) used to quickly determine the mass of individual items, such as packages, without the intervention of a human operator.
EURAMET’s calibration guidelines provide guidance to help harmonize calibrations across the European metrology community. The new guide provides a consistent approach to improve mass measurements. The guide covers key aspects of the calibration process including determining test load reference values, evaluating uncertainty, and the contents of the associated calibration certificate, and is applicable to both dynamic and static (“start-stop”) weighing systems.
As part of its work developing methods for AWIs, completed EMPIR project “Traceable calibration of automatic weighing instruments operating in the dynamic mode” (AWICal, 14RPT02) produced a draft version of Calibration Guideline No. 26. This draft was then finalized as a EURAMET calibration guide by the EURAMET Technical Committee for Mass and Related Quantities (TC-M).
Matej Grum (MIRS) was the coordinator of the EMPIR AWICal project (2015-2018) and coordinator of the EURAMET 1536 project for Finalisation of the draft Calibration Guideline on the Calibration of Automatic Catchweighing Instruments (2021-2023). IMBiH participated in these projects, and it is one of the authors.
The authors are from MIRS Slovenia, IMBiH Bosnia and Herzegovina, Mettler Toledo Spain, UME Türkiye, PTB Germany, CMI Czechia, DMDM Serbia, AMSS-CMV Serbia, and BEV Austria.
