MEASURAND : Activity concentration in 3H
NOMINAL VALUE : 37 kBq g-1
|
The key comparison reference value is obtained by applying the power moderated weighted mean of the results giving |
|
The degree of equivalence of each laboratory with respect to the reference value is given by a pair of terms: |
| When required, the degree of equivalence between two laboratories can be evaluated by a pair of terms: Dij = Di - Dj = (xi - xj) and Uij, its expanded uncertainty (k = 2), both expressed in kBq g-1. The approximation Uij ~ 2(ui2 + uj2)1/2 may be used for the computation of the pair-wise degrees of equivalence. |
