This document specifies performance criteria for the selection of single-laboratory validated or collaborative-trial validated methods of analysis of elements and their chemical species in feed. The terms and definition of the relevant parameters for method validation are included. The performance requirements and characteristics are provided. This document may serve as a guide:
— to assess the quality of new European Standard methods under validation;
— to review the quality of previous collaborative trials;
— to confirm the extension of the scope of an already published European Standard applied to other analyte concentrations or matrices; or
— to evaluate the fitness-for-purpose of single-validated methods.
The performance criteria can apply to methods dedicated to the determination of heavy metals, trace elements, major elements and minerals.
