Methods suitable for official control shall produce results with a combined standard measurement uncertainty (u) less than the maximum standard measurement uncertainty calculated using the formula below:\nUf=LOD∕22+αC2where:\nUf is the maximum standard measurement uncertainty (μg/kg);\nLOD is the limit of detection of the method (μg/kg). The LOD must meet the performance criteria set out in point C.3.3.1 for the concentration of interest;\nC is the concentration of interest (μg/kg);\nα is a numeric factor to be used depending on the value of C.
