SUBJECT Anionic impurities and lead in salt solutions
MEASURAND Mass fraction of bromide
The key comparison reference value xR and its associated standard uncertainty uR are determined from the median.
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 the same unit:
Di = (xi - xR) and its expanded uncertainty Ui at a 95 % level of confidence.
