Division 4.2.1 Residues in and/or on plants, plant products, foodstuffs (of plant and animal origin), feedingstuffsF1

Methods submitted must be suitable for the determination of all components included in the residue definition as submitted in accordance with points 6.1 and 6.2 in order to enable F2competent authorities to determine compliance with established MRL’s or to determine dislodgeable residues.

The specificity of the methods must enable all components included in the residue definition to be determined, using an additional confirmatory method if appropriate.

The repeatability must be determined and reported. The replicate analytical portions for test can be prepared from a common field treated sample, containing incurred residues. Alternatively the replicate analytical portions for test can be prepared from a common untreated sample with aliquots fortified at the required level(s).

The results from an independent laboratory validation must be reported.

The limit of determination including the individual and mean recovery must be determined and reported. The overall relative standard deviation, as well as the relative standard deviation for each fortification level must be experimentally determined and reported.
