The key comparison reference value, xR, is calculated as the weighted mean of the participants' results for Re = 70 000 and Re = 300 000. For Re = 100 000, xR is calculated as the median. Its expanded uncertainty is UR. |
| The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms, both expressed in relative terms: Di and Ui. Di = (xi - xR). For Re = 70 000 and Re = 300 000 its expanded uncertainty is Ui = (ULab i2 - UR2)1/2. For Re = 100 000 the uncertainty was calculated using Monte carlo methods. |
| The degree of equivalence between two laboratories i and j may be calculated approximately by Dij = (Di - Dj) and the associated expanded uncertainty Uij = (ULab i2 + ULab j2)1/2. |
