For each transfer thermometer, the key comparison reference value x_R was calculated using the median of the reported results and its associated standard uncertainty u_R calculated using the 'median of absolute deviations (MAD)' method as described in Section 10.3 of the CCT-K10 Final report. u_R-totalis the total uncertainty of the reference value, including components for drift, corrections and uncertainty in the median value.

Thermometer	x_R	u_R	u_R-total
LP3 thermometer	4.19878 × 10^-11 A	0.04 °C	0.06 °C
Chino thermometer	0.004871 V	0.03 °C	0.10 °C

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 °C:

D_i and its expanded uncertainty U_i (at 95% level of confidence) are computed according to Section 11 of the CCT-K10 Final report, where for each participant at each temperature, D_i has been calculated by taking the average (simple mean) of the differences between each participant's LP3 and Chino thermometer values, from their respective reference values (medians). The uncertainty U_i at each temperature was taken to be, for that participant, the largest total uncertainty (laboratory uncertainty combined with the uncertainty in the reference value); that is, the larger of the total uncertainty for the LP3 and Chino thermometer. Where data for one of the thermometers had been withdrawn from the comparison, the uncertainty was simply the total uncertainty related to the remaining thermometer.

The key comparison reference value x_R and its associated standard uncertainty u_R are calculated from the weighted mean with cut-off according to Section 12 of the CCT-K10 Final report. u_R-totalis the total uncertainty of the reference value, including components for the furnace, cell stability, corrections and uncertainty in the weighted mean value.

x_R = 1324.75 °C u_R = 0.04 °C u_R-total = 0.16 °C

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 °C:

D_i = (x_i - x_R) and U_i its expanded uncertainty (at 95%level of confidence) is computed according to equation (14) in Section 12 of the CCT-K10 Final report.
