CCM.F-K1.a and CCM.F-K1.b

MEASURAND : Force
NOMINAL VALUE : 5 kN

The key comparison reference value, xR 5 kN, has been calculated as the weighted mean of the mean relative deviations obtained for 5 kN (CCM.F-K1.a and CCM.F-K1.b together). Its standard uncertainty, uR 5 kN, is obtained as the standard uncertainty of the weighted mean (see Section 3.4.4 on page 52 of the Final Report).

xR 5 kN = -0.59 10-5 and 2uR 5 kN = 0.66 10-5

The degree of equivalence of each laboratory with respect to the reference value is given by a pair of terms, both expressed in 10-5: Di and Ui, its expanded uncertainty (k = 2), (see Section 3.4.8 on page 53 of the Final Report).

The degree of equivalence between two laboratories is given by a pair of terms, both expressed in 10-5: Dij and Uij, its expanded uncertainty (k = 2), (see Section 3.4.8 on page 53 of the Final Report).

CCM.F-K1.a

MEASURAND : Force
NOMINAL VALUE : 10 kN

The key comparison reference value, xR 10 kN, has been calculated as the weighted mean of the mean relative deviations obtained for 10 kN (CCM.F-K1.a only). Its standard uncertainty, uR 10 kN, is obtained as the standard uncertainty of the weighted mean (see Section 3.4.4 on page 52 of the Final Report).

xR 10 kN = -1.05 10-5 and 2uR 10 kN = 0.77 10-5

The degree of equivalence of each laboratory with respect to the reference value is given by a pair of terms, both expressed in 10-5: Di and Ui, its expanded uncertainty (k = 2), (see Section 3.4.8 on page 53 of the Final Report).

The degree of equivalence between two laboratories is given by a pair of terms, both expressed in 10-5: Dij and Uij, its expanded uncertainty (k = 2), (see Section 3.4.8 on page 53 of the Final Report).
