The key comparison reference value x_R and its associated standard uncertainty u_R are determined from the median of eight results. Secondary measurement results traceable to CRMs from SMU (a participating NMI) and those using non-NMI CRMs as calibrants were excluded. Secondary measurement results traceable to DFM (a non-participating NMI) were first combined into a single result using the uncertainty-weighted mean without dispersion before being included in the x_R calculation (see section 8 of the CCQM-K170 Final report).

The degree of equivalence of laboratory i relative to the key comparison reference value x_R is given by a pair of terms, both expressed in S.m^-1:

D_i = (x_i - x_R) and its expanded uncertainty U_i at a 95 % level of confidence calculated as described in section 9 of the CCQM-K170 Final report.

The key comparison reference value x_R and its associated standard uncertainty u_R are determined from the median of six results. Measurement results for participants who reported technical problems and those using non-NMI CRMs as calibrants were excluded. Secondary measurement results traceable to DFM (a non-participating NMI) were first combined into a single result using the uncertainty-weighted mean without dispersion before being included in the x_R calculation (see section 8 of the CCQM-K170 Final report).
