MEASURAND     Mass fraction of Deoxynivalenol (DON) in acetonitrile (ACN)

NOMINAL RANGE   9 mg/kg to 125 mg/kg

Degrees of equivalence represented by D_i = (x_I - x_Ri) and its expanded uncertainty U_i at a 95 % level of confidence, both expressed in mg/kg.

The samples are indicated by A and B.

(CBKT) – sample provided by the laboratory is prepared using a value assigned stock solution of DON in ACN supplied within the "Metrology for Safe Food and Feed in Developing Economies" Capacity Building Programme;
(own) – sample provided by the laboratory is prepared based on the laboratory’s own characterized source material.

NOMINAL RANGE   9 mg/kg to 125 mg/kg

For each sample preparation, the value of the DON mass fraction, x_Ri,  assigned by the BIPM according to the calibration procedure described in the Final report, and its associated combined uncertainty, u_Ri,  is taken as the key comparison reference value for laboratory i.

For each sample, the degree of equivalence of each laboratory i with respect to the reference value is given by a pair of terms both expressed in mg/kg:

D_i = (x_i - x_Ri ) and U_i, its expanded uncertainty at a 95% level of confidence, U_i = 2(u_i ² + u_Ri ²)^1/2
