Key comparison reference value:

Resistance ratios are used with calibration equations for each thermometer to obtain temperature Ti.
The key comparison reference temperature, TR, is calculated from the mean of the average temperatures from the participants' results, excluded SRPT measurements that fail the cutoff criteria described in section 3.5 of the Final Report, and its associated  standard uncertainty uR is  computed as explain in section 2.4 of the Final Report.

 

        TR = -0.20 mK     uR = 0.11 mK

 

The degree of equivalence of laboratory i relative to the key comparison reference value TR is given by a pair of terms, both expressed in mK:

 

Di = (Ti - TR) and its expanded uncertainty Ui at a 95 % level of confidence is computed as described in section 2.3 of the Final Report.
