Introduction to WP2

The aim of this work package is to implement calibration methods to realise, improve and maintain the mass scale (e.g. from 1 mg to 20 kg with uncertainties of 0.001 mg –3 mg or better) in countries where mass scale measurement capabilities are less developed (e.g. Bosnia and Herzegovina, North Macedonia, Ireland, Belgium, Serbia, Bulgaria). This work package aims to provide practical experience of the dissemination process (this is different from WP1 where the work is focused on the development of the written procedures). Small and developing NMIs will use their available accurate weighing systems, which they have obtained in recent years, as well as their 1 kg mass standards.
