Abstract
From October 2009 to November 2010 a star-shaped comparison in mass measurements was carried out between CARIMET countries. The Bureau of Standards Jamaica (BSJ) acted as the pilot laboratory.Six travelling standards were circulated with the following nominal values: 2 kg, 1 kg, 200 g, 50 g, 1 g and 200 mg. These travelling standards complied with the accuracy requirements of OIML class E2. The results of the intercomparison are presented here.In general, the agreement between all participants is very good, except for the 50 g weight where one laboratory clearly made an outlier measurement.Main text.To reach the main text of this paper, click on Final Report.
