Proficiency testing for calibration of multimeter
CT2M, Route de Lançon, Centre des Creusets, 13250 Saint-Chamas, France
In 2018 and 2019, CT2M organize an inter-laboratory comparison of multimeter calibration in which 27 Europeans laboratories participated. Among them were calibration laboratories (accredited or not) but also laboratories performing themselves the calibrations of their multimeter. The principle of this inter-laboratory comparison is to circulate a multimeter from one laboratory to another in order to compare the calibration results (including correction and calibration uncertainty). The processing of the results is carried out according to the ISO 13528 statistical principles and in compliance with the requirements of ISO 17043. A final report in 2019 will indicate to the participants all the results in anonymous way and the performance scores to evaluate the ability of laboratories to carry out this calibration. This article will present the organization of this inter-laboratory comparison as well as the results obtained.
