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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 3657 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee
SC 11, Animal and vegetable fats and oils.
This third edition cancels and replaces the second edition (ISO 3657:1988), which has been technically revised.
Annex A of this International Standard is for information only.
