Assigned values and scores
Reference values of the comparison samples will be established either by gravimetric spiking, reference values from one expert laboratory or consensus values from participants’ measurement values. The individual reported results will be compared to these assigned values and performance statistics scores will be calculated.
Homogeneity and stability of the PT test items will be checked and confirmed during the PT exercise.
Participation costs
The participation in this PT is at a cost of 250 EUR, but the sample analysis related costs have to be covered by the participants and not by the PT organizer.
