CCAUV.V-K3,  EURAMET.AUV.V-K3 and APMP.AUV.V-K3.1 

MEASURAND:  Magnitude

FREQUENCY :  0.1 Hz

 

CCAUV.V-K3

The computation of the key comparison reference value at each frequency, xR, and of its expanded uncertainty, UR (k = 2), is explained in Section 8 of the CCAUV.V-K3 Final Report and is based on a weighted mean.

 

        xR = 136.75 mV / (m/s2)      UR = 0.15 mV / (m/s2)

 

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: Di where Di = xi - xR, and its expanded uncertainty Ui (k = 2), computed as explained in Section 8 of the CCAUV.V-K3 Final Report.
