The key comparison reference value, xR, is calculated as the weighted average of the mean relative deviations from the pilot laboratory obtained by the participating laboratories. Its standard uncertainty, uR, is calculated as explained on page 30 of the CCM.F-K2.a and CCM.F-K2.b Final Report.

 

        xR = 0.47 × 10-5       uR = 0.33 × 10-5

 

The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in × 10-5:

Di = (xi - xR) and its expanded uncertainty Ui at a 95 % level of confidence calculated as the sum in quadrature of the uncertainty associated with the deviation from the pilot value and the uncertainty of the KCRV (see page 32 of the CCM.F-K2.a and CCM.F-K2.b Final Report .

CCM.F-K2.a and CCM.F-K2.b

Measurements in key comparisons CCM.F-K2.a and CCM.F-K2.b correspond to the schemes A and B respectively, as explained on page 4 of the CCM.F-K2 (a and b) Final Report. Two transducers are used in scheme A, and three transducers are used in scheme B:
- in scheme A, the two transducers have a nominal capacity of 100 kN and are used to measure 50 kN and 100 kN forces;
- in scheme B, two transducers have a nominal capacity of 50 kN and are used to measure 50 kN forces, and one transducer has a nominal capacity of 100 kN and is used to measure 50 kN forces.

Detailed results of measurements obtained in both key comparisons are given in Section 9 on page 18 of the Final Report. They are then concatenated (see page 30 of the Final Report) in order to provide one set of measurements for 50 kN forces and one set of measurements for 100 kN forces.
