CCM.D-K4

The key comparison CCM.D-K4 was carried out in two "petals". A reference value was calculated for each transfer instrument and petal. The method how to calculate a common key comparison reference value, xR , and associated expanded uncertainty at a 95% confidence level, UR,and the reciprocal Degrees of Equivalence is described  on pages 14 to 19 of the CCM.D-K4 Final Report and in Section 3.2.1 of the Supplement to CCM.D-K4.

 

The degree of equivalence, Di, of laboratory i with respect to the key comparison reference value is given by a par of therms: the difference Di and its expanded uncertainty (95% confidence level) Ui .
