The key comparison reference value x_{R} is calculated as the weighted mean of the results of all participants in CCEM-K11. The value of the mean of the seven results of SP is used for the computation of x_{R}, see equations 10 and 11 of the Final Report. The standard uncertainty u_{R} of x_{R} is computed as explained in section 6.1.4 of the Final Report. x_{R} = 1.6 µV/V; 2u_{R} = 9.2 µV/V |
The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms both expressed in µV/V: D_{i} = (x_{i} - x_{R}) and its expanded uncertainty U_{i} (k = 2). The equations for the computation of U_{i}_{ }are given in section 6.1.6 of the Final Report. |
The degree of equivalence between two laboratories i and j is given by two terms both expressed in µV/V: D_{ij} = (x_{i} - x_{j}) and its expanded uncertainty U_{ij} (k = 2). The equations for the computation of U_{ij }are given in section 6.1.7 of the Final Report. |

The values reported by the participants in EUROMET.EM-K11 are given in Table 9 (page 14) and Table 10 (page 18) of the EUROMET.EM-K11 Final Report for 100 mV and 10 mV, respectively.
Measurements were conducted between June 2005 and Aoril 2008.
The results after correction for the drift of the travelling standard are reported in Section 6.1.8 of the EUROMET.EM-K11 Final Report (page 22 to page 29).
