Animal and vegetable fats and oils - Determination of acid value and acidity (ISO 660:2009)
This International Standard specifies three methods (two titrimetric and one potentiometric) for the determination of the acidity in animal and vegetable fats and oils, hereinafter referred to as fats. The acidity is expressed preferably as acid value, or alternatively as acidity calculated conventionally. This International Standard is applicable to refined and crude vegetable or animal fats and oils, soap stock fatty acids or technical fatty acids. The methods are not applicable to waxes. Since the methods are completely non-specific, they cannot be used to differentiate between mineral acids, free fatty acids, and other organic acids. The acid value, therefore, also includes any mineral acids that may be present.
Tierische und pflanzliche Fette und Öle - Bestimmung der Säurezahl und der Azidität (ISO 660:2009)
Diese Internationale Norm legt drei Verfahren (zwei titrimetrische und ein potentiometrisches) zur Bestimmung der Azidität in tierischen und pflanzlichen Fetten und Ölen, die im Folgenden als Fette bezeichnet werden, fest. Die Azidität wird vorzugsweise als Säurezahl ausgedrückt, alternativ als konventionell berechnete Azidität.
Die Norm gilt für raffinierte und rohe pflanzliche oder tierische Fette und Öle, Soapstock Fettsäuren oder technische Fettsäuren. Die Verfahren gelten nicht für Wachse.
Da die Verfahren vollkommen unspezifisch sind, können diese zur Unterscheidung zwischen Mineralsäuren, freien Fettsäuren und sonstigen organischen Säuren nicht angewendet werden. Die Säurezahl umfasst daher auch möglicherweise vorhandene Mineralsäuren.
Corps gras d'origines animale et végétale - Détermination de l'indice d'acide et de l'acidité (ISO 660:2009)
L'ISO 660:2009 spécifie trois méthodes (deux titrimétriques et une potentiométrique) pour la détermination de l'acidité dans les corps gras d'origines animale et végétale dits corps gras. L'acidité est exprimée, de préférence, en indice d'acide ou bien en acidité calculée conventionnellement.
L'ISO 660:2009 est applicable aux corps gras d'origines végétale ou animale à l'état brut ou raffinés, aux acides gras des pâtes de neutralisation ou aux acides gras de qualité technique. Ces méthodes ne sont pas applicables aux cires.
Ces méthodes ne sont en aucun cas spécifiques, elles ne peuvent donc pas être utilisées pour différencier les acides minéraux, les acides gras libres et autres acides organiques. De ce fait, l'indice d'acide inclut tout acide minéral potentiellement présent.
