Animal and vegetable fats and oils - Determination of insoluble impurities content (ISO 663:2017)
ISO 663:2017 specifies a method for the determination of the insoluble impurities content of animal and vegetable fats and oils.
If it is not desired to include soaps (particularly calcium soaps) or oxidized fatty acids in the insoluble impurities content, it is necessary to use a different solvent and procedure. In this case, an agreement is to be reached between the parties concerned.
Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this document.
Tierische und pflanzliche Fette und Öle - Bestimmung des Anteils an unlöslichen Verunreinigungen (ISO 663:2017)
Dieses Dokument legt ein Verfahren zur Bestimmung des Anteils an unlöslichen Verunreinigungen in tierischen und pflanzlichen Fetten und Ölen fest.
Falls es unerwünscht ist, Seifen (besonders Calciumseifen) oder oxidierte Fettsäuren dem Anteil an unlös-lichen Verunreinigungen zuzurechnen, ist es notwendig, ein anderes Lösemittel und Verfahren anzuwenden. In diesem Fall sollte das Verfahren zwischen den Beteiligten vereinbart werden.
Milch und Milcherzeugnisse (oder Fett aus Milch und Milcherzeugnissen) sind vom Anwendungsbereich dieses Dokumentes ausgenommen.
Corps gras d'origines animale et végétale - Détermination de la teneur en impuretés insolubles (ISO 663:2017)
ISO 663:2017 spécifie une méthode de détermination de la teneur en impuretés insolubles des corps gras d'origines animale et végétale.
S'il est préférable de ne pas inclure les savons (en particulier les savons de calcium) ou les acides gras oxydés dans la teneur en impuretés insolubles, l'utilisation d'un solvant et d'un mode opératoire différents est nécessaire. Dans ce cas, un accord est à convenir entre les parties concernées.
Le lait et les produits laitiers (ou les corps gras issus du lait et des produits laitiers) sont exclus du domaine d'application du présent document.
Rastlinske in živalske maščobe in olja - Določevanje netopnih nečistoč (ISO 663:2017)
Ta dokument določa metodo za določevanje vsebnosti netopnih nečistoč živalskih in rastlinskih masti in olj.
Za izključitev mil (zlasti mil na osnovi kalcija) ali oksidiranih maščobnih kislin iz vsebnosti netopnih nečistoč je treba uporabiti drugo topilo in postopek. V tem primeru morajo zadevne stranke skleniti dogovor.
Mleko in mlečni izdelki (ali maščoba iz mleka in mlečnih izdelkov) niso zajeti v tem dokumentu.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

insoluble impurities content
quantity of dirt and other foreign matter insoluble in n-hexane or light petroleum under the conditions
specified in this document
Note 1 to entry: The content is expressed as a percentage by mass.
Note 2 to entry: These impurities include mechanical impurities, mineral substances, carbohydrates, nitrogenous
substances, various resins, calcium soaps, oxidized fatty acids, fatty acid lactones, and (in part) alkali soaps,
hydroxy-fatty acids and their glycerides.
4 Principle
A test portion is treated with an excess of n-hexane or light petroleum, then the solution obtained is
filtered. The filter and residue are washed with the same solvent, then dried at 103 °C and weighed.
