CCRI(II)-K2.Fe-55.2019
MEASURAND Activity concentration of a solution
NOMINAL VALUE 100 kBq/g
The key comparison reference value xR and its associated standard uncertainty uR are computed from a power moderated mean of the reported results, see CCRI(II)-K2.Fe-55 Final Report where
xR = 101.49 kBq/g uR = 0.23 kBq/g
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 kBq/g.
