Animal and vegetable fats and oils - Determination of water content - Karl Fischer method (pyridine free) (ISO 8534:2008)

This International Standard specifies a method for the determination of the water content of animal and vegetable fats and oils (hereinafter referred to as fats) using Karl Fischer apparatus and a reagent which is free of pyridine.

Tierische und pflanzliche Fette und Öle - Bestimmung des Wassergehalts - Karl-Fischer-Verfahren (pyridinfrei) (ISO 8534:2008)

Diese Internationale Norm legt ein Verfahren zur Bestimmung des Wassergehalts in tierischen und pflanzlichen Fetten und Ölen (nachfolgend als Fette bezeichnet) fest, bei dem die Apparatur nach Karl Fischer und ein pyridinfreies Karl Fischer Reagenz angewendet werden. Die Fette dürfen keine Verunreinigungen enthalten, wie alkalische Verbindungen (Seifen) und Peroxide, die mit dem Reagenz so reagieren, dass ein zu hoher Wert für die Ergebnisse erhalten wird.
Die Größe der zur Wasserbestimmung vorgesehenen Probe wird so ausgewählt, dass ihr Wassergehalt für die volumetrische Titration (Beschreibung im Hauptteil dieser Norm) zwischen 1 mg und 100 mg Wasser liegt und für die coulometrische Titration (Anhang B dieser Norm) zwischen 10 µg und 10 mg, wobei zur Bestimmung die Apparatur nach Karl Fischer und Karl Fischer Reagenzien angewendet werden, die mit Wasserstandard Lösungen über den erforderlichen Bereich validiert wurden. Für die volumetrische Titration muss eine Mindestmenge des Karl Fischer Reagenzes von 0,5 ml angewendet werden.
