The CT2M organized in 2018 a european inter-laboratory comparison (ILC) for the calibration of masses. The proficiency testing was particulary intended for the calibration laboratories (accredited or not) but also the testing laboratories carrying out their own calibrations and / or controls of their masses. This circuit took place between April 2018 to October 2018 in five European countries: England, France, Germany, Portugal and Switzerland. The results were processed according to the statistical principle of ISO 13528  and in compliance with the requirements of ISO 17043 . This article presents the organization of this inter-laboratory comparison and the results. The performances of the participants are evaluated and an interpretation of the results is proposed in order to highlight the predominant influence parameters on the mass calibration results (nominal values: 200mg, 2g, 20g, 200g and 20kg).
