Description
Summary:Main textSince 2013, 6 laboratories have submitted 7 samples of 68Ge to the International Reference System (SIR) for activity comparison at the Bureau International des Poids et Mesures (BIPM), with comparison identifier BIPM.RI(II)-K1.Ge-68. Recently, the NIM (China) participated in the comparison and the key comparison reference value (KCRV) has been updated. The degrees of equivalencebetween each equivalent activity measured in the SIR or linked to the SIR from the CCRI(II)-K2.Ge-68 comparison and the updated KCRV have been calculated and the results are given in the form of a table. A graphical representation is also given.To reach the main text of this paper, click on Final Report. Note that this text is that which appears in Appendix B of the BIPM key comparison database https://www.bipm.org/kcdb/.The final report has been peer-reviewed and approved for publication by the CCRI, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA).
