MEASURAND : Mass fraction of Sulfur in diesel fuel
NOMINAL VALUE : ~ 42 µg/g
| The key comparison reference value, xR, is computed as the Mixture Model median of all results (see page 11 of the Final Report). Its expanded uncertainty at 95% level of confidence is denoted UR. xR = 42.17 µg/g, UR = 1.32 µg/g |
|
The degree of equivalence of laboratory i relative to the key comparison reference value is given by a pair of terms, both expressed in µg/g: |
| No pair-wise degrees of equivalence are calculated for this key comparison. |
