MEASURAND : Temperature T90 expressed in K
NOMINAL TEMPERATURE : T90 = 16.999 K

For each temperature in the comparison the key comparison reference value, TR, is the weighted mean of Ti, the individual temperature values of thermometers.
The weighted mean is calculated using the laboratory uncertainty combined with the comparison uncertainty, to set the weights.
TR is used as the baseline for the comparison, but has no special significance with respect to the ITS-90, and is used without uncertainty.

TR = 16.999335 K

The degree of equivalence of each temperature Ti with respect to the key comparison reference value, TR, is given by a pair of terms:
Di = (Ti -TR) and Ui, its expanded uncertainty at 95 % confidence, both expressed in mK. Ui includes the uncertainties in the original laboratory calibrations and in the comparison measurements, but not in TR.

EURAMET.T-K1 was linked to CCT-K1 via NPL, PTB and VSL who participated in both comparisons.
