MEASURAND : Temperature T90 expressed in K
NOMINAL TEMPERATURE : T90 = 2.601 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. TR = 2.600776 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. |

For each temperature in the comparison the key comparison reference value, TR, is the weighted mean of Ti, the individual temperature values of thermometers. TR = 22.676998 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.
