In phase : xR = -49.7 nV/V and UR = 5.0 nV/V
Quadrature : xR = 59.6 nV/V
and UR = 3.7 nV/V

The degree of equivalence of each laboratory with respect to the key comparison reference value is given by a pair of terms:
Di and Ui, its expanded uncertainty (k = 2), both expressed in nV/V.

The degree of equivalence between two laboratories i and j is given by a pair of terms: Dij and Uij, its expanded uncertainty (k = 2), both expressed in nV/V, and can be found in section 3 of the Final report, Part 2.

The measurements of this key comparison were made of twenty AC voltage ratios at two possible frequencies: 1 kHz and 55 Hz. The in-phase and quadrature components of each voltage ratio were reported separately giving a total of 80 possible measurement results for each participant. The 1 kHz measurements were compulsory and all the 17 participating laboratories made these measurements. The 55 Hz measurements were optional, with 7 laboratories contributing.
