MEASURAND : Electrolytic conductivity of a KCl solution
NOMINAL VALUE : 0.05 S/m
| The key comparison reference value, xR, is calculated as the weighted mean of the participants' results excluding outliers, and its standard uncertainty, uR, is calculated as explained on page 15 of the Final Report. |
xR = 0.0500304 S/m and uR = 0.0000061 S/m
|
The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms: Di = (xi - xR) and Ui, its expanded uncertainty (k = 2), |
| There are no pair-wise degrees of equivalence computed for this key comparison. |
| INMETRO and CENAM provide the link between key comparisons CCQM-K92 and SIM.QM-K92 as described on page 8 of the SIM.QM-K92 Final Report. |
|
The degree of equivalence of laboratory i participant in SIM.QM-K92 only relative to the CCQM-K92 key comparison reference value is given by a pair of terms: Di and Ui, its expanded uncertainty (k = 2), both expressed in S/m and computed according to Equations 2 and 3 of the SIM.QM-K92 Final Report. |
