Animal and vegetable fats and oils - Determination of saponification value (ISO 3657:2002)

This International Standard specifies a method for the determination of the saponification value of animal and vegetable fats and oils. The saponification value is a measure of the free and esterified acids present in fats and fatty acids.
The method is applicable to refined and crude vegetable and animal fats.
If mineral acids are present, the results given by this method are not interpretable unless the mineral acids are determined separately.

Tierische und pflanzliche Fette und Öle - Bestimmung der Verseifungszahl (ISO 3657:2002)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Verseifungszahl von tierischen und pflanz-lichen Fetten und Ölen fest. Die Verseifungszahl ist ein Maß für die Menge an freien und veresterten Säuren, die in Fetten und Fettsäuren vorhanden sind.
Das Verfahren ist für raffinierte und rohe pflanzliche und tierische Fette geeignet.
Bei Vorhandensein anorganischer Säuren sind die nach diesem Verfahren erhaltenen Ergebnisse nicht aus-wertbar, es sei denn, die anorganischen Säuren wurden getrennt bestimmt.

Corps gras d'origines animale et végétale - Détermination de l'indice de saponification (ISO 3657:2002)

La présente Norme internationale spécifie une méthode pour la détermination de l'indice de saponification des corps gras d'origines animale et végétale. L'indice de saponification est une mesure des acides libres et estérifiés présents dans les corps gras et les acides gras.
La méthode est applicable aux corps gras d'origines végétale et animale raffinés et bruts.
En présence d'acides minéraux, les résultats donnés par cette méthode ne sont plus interprétables si l'on ne dose pas séparément l'acidité minérale.
