Edition date: 2025-03-07
In Force
Available languages: English, German, French
Summary: Dieses Dokument legt Leistungskriterien für die Auswahl von in Einzellaboratorien validierten oder in Laborvergleichsuntersuchungen validierten Analyseverfahren für Elemente und ihren Verbindungen in Futtermitteln fest. Enthalten sind die Begriffe der relevanten Parameter für die Verfahrensvalidierung. Die Leistungsanforderungen und merkmale werden zur Verfügung gestellt. Dieses Dokument darf als Orientierung dienen für: - die Beurteilung der Qualität neuer Europäischer Normverfahren während ihrer Validierung; - die Überprüfung der Qualität vorangegangener Laborvergleichsuntersuchungen; - die Bestätigung der Erweiterung des Anwendungsbereichs einer bereits veröffentlichten Europäischen Norm, die für andere Analytkonzentrationen oder Matrices angewendet wurde; oder - die Evaluierung der Gebrauchseignung einfach validierter Verfahren. Die Leistungskriterien können bei Verfahren zur Bestimmung von Schwermetallen, Spurenelementen, Hauptelementen und Mineralien verwendet werden.

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.

Le présent document spécifie les critères de performance pour la sélection de méthodes validées par un ou plusieurs laboratoires pour l’analyse des éléments minéraux et de leurs espèces chimiques dans les aliments composés pour animaux. Les termes et définitions de paramètres pertinents pour la validation des méthodes sont inclus. Les exigences de performance et les caractéristiques sont fournies. Le présent document peut servir de guide : - pour évaluer la qualité des nouvelles méthodes de Norme européenne en cours de validation ; - pour examiner la qualité de précédents essais interlaboratoires ; - pour confirmer l’extension du domaine d’application d’une Norme européenne déjà publiée appliquée à d’autres concentrations ou matrices d’analytes ; ou - pour évaluer l’adaptation à l’objectif de méthodes validées par un seul laboratoire. Les critères de performance peuvent s’appliquer aux méthodes dédiées au dosage des métaux lourds, des éléments trace, des éléments majeurs et des minéraux.
