Key comparison CCPR-K5 and EURAMET.PR-K5

MEASURAND : Spectral diffuse reflectance
WAVELENGTH : 360 nm to 460 nm

CCPR-K5 

Degrees of equivalence are produced from the combined results of both types of samples, but excluding data from 360 nm to 440 nm of ceramic tile samples (reasons for this are explained in Section 12 of the Final Report).
For each wavelength, the key comparison reference value was calculated as a weighted mean of the participants' results with a cut-off, as detailed in Section 13 of the Final Report (see Tables 13.1 and 13.2).

 

The degree of equivalence of each laboratory with respect to the reference value is given by a pair of relative terms:
Di and Ui, its expanded uncertainty (k = 2), both expressed in % (see equations 13.18 and 13.19 on page 147 of the Final Report).

EURAMET.PR-K5

The linking of EURAMET.PR-K5 to CCPR-K5 is made via METAS who participated in both comparisons.
