For each nominal pressure value, the key comparison reference value, pR, is obtained from an unweighted mean of the measurement method means, excluding CENAM for the determination of pR at 10 Paz and 30 Pa.
The combined standard uncertainty of pR is uR .
| The degree of equivalence of each laboratory with respect to the reference value is given by a pair of terms: Di = (pi - pR) and Ui, its expanded uncertainty at a (k = 2), both expressed in Pa. |
| The degree of equivalence between two laboratories is given at p. 29 of the Final Report. |
