MEASURAND : Equivalent activity of 207Bi
|
Key comparison reference value: |
| The degree of equivalence of each laboratory with respect to the reference value is given by a pair of terms: Di = (xi - xR) and Ui, its expanded uncertainty (k = 2), both expressed in kBq, and Ui = 2((1 - 2wi)ui2 + uR2)1/2 when each laboratory has contributed to the calculation of xR with a weight wi. |
