Abstract
Significant discrepancies emerged between the density reference standards of the IMGC and of other NMIs, contrasting with the good agreement of previous comparisons. The reason of these contrasting results lies in a systematic effect linked to the individual pair of standards being compared, due to the balance and to the procedure adopted
