MEASURAND : Mass fraction of Iodine (I) in infant formula
|
The key comparison reference value, xR, is calculated as the median of the participants’ results without INM (RO) results, and its standard uncertainty, uR, is computed as explained in section 5.2 of the Final Report. |
| The degree of equivalence of each laboratory i with respect to the key comparison reference value is given by a pair of terms, both expressed in mg/kg: Di = (xi - xR) and Ui, its expanded uncertainty (k = 2), Ui = 2(ui2 + uR2)1/2. |
