Extent: E+W+S+N.I.

Methods for analysis in water for parent compound and/or relevant metabolites must be submitted.
The specificity of the methods must enable the parent compound and/or relevant metabolites to be determined, using an additional confirmatory method if appropriate.
The repeatability, recovery and 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.
For drinking water the proposed limit of determination must not exceed 0,1 μg/l. For surface water the proposed limit of determination must not exceed a concentration which has an impact on non-target organisms deemed to be unacceptable in accordance with the requirements of the Annex to Commission Regulation (EU) No 546/2011.
