  • Key comparison CCEM-K12

The key comparison reference value, xR, is computed as the weighted average of the results of those participants who have an independent realisation of primary standards for current AC-DC difference and a low reported uncertainty (see Section 6 of the CCEM-K12 Final Report).
At 10 mA, the key comparison reference values are based on the measurements carried out by NMIA, NIST, NRC, PTB, BEV, SP, and VNIIM.

The combined standard uncertainty, uR, of xR is the standard uncertainty of the weighted average (see equation 2 on page 11 of the Final Report).
For 10 mA and 10 Hz, xR = 2.6 µA/A and 2uR = 0.9 µA/A

The degree of equivalence of laboratory i relative to the key comparison reference value is given by a pair of terms both expressed in µA/A: Di = xi - xR, and its expanded uncertainty (k = 2) Ui obtained from equations 4, 5 and 6 on page 11 of the CCEM-K12 Final Report.
