Abstract: Two new participations in the BIPM.RI(II)-K1.Lu-177 comparison have been added to the previous results and this has produced a revised value for the key comparison reference value (KCRV), calculated using the power-moderated weighted mean. A link has been made to the CCRI(II)-K2.Lu-177 comparison held in 2009 through the NPL and IRMM who participated in both comparisons. Two NMIs used the K2 comparison to update their degree of equivalence. The degrees of equivalence between each equivalent activity measured in the International Reference System (SIR) and the KCRV have been calculated and the results are given in the form of a table for the remaining two NMIs in the BIPM.RI(II)-K1.Lu-177 comparison and the nine other participants in the CCRI(II)-K2.Lu-177 comparison. A graphical presentation is also given.
