EN ISO 12966-4:2015

Animal and vegetable fats and oils - Gas chromatography of fatty acid methyl esters - Part 4: Determination by capillary gas chromatography (ISO 12966-4:2015)

ISO 12966-4:2015 specifies a method for the determination of fatty acid methyl esters (FAMEs) derived by transesterification or esterification from fats, oils, and fatty acids by capillary gas chromatography (GLC). Fatty acid methyl esters from C8 to C24 can be separated using this part of ISO 12966 including saturated fatty acid methyl esters, cis- and trans-monounsaturated fatty acid methyl esters, and cis- and trans-polyunsaturated fatty acid methyl esters.
The method is applicable to crude, refined, partially hydrogenated, or fully hydrogenated fats, oils, and fatty acids derived from animal and vegetable sources.
This method is not suitable for the analysis of dairy, ruminant fats and oils, or products supplemented with conjugated linoleic acid (CLA). Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this part of ISO 12966.
ISO 12966-4:2015 is not applicable to di-, tri-, polymerized and oxidized fatty acids, and fats and oils.

Tierische und pflanzliche Fette und Öle - Gaschromatographie von Fettsäuremethylestern - Teil 4: Bestimmung mittels Kapillargaschromatographie (ISO 12966-4:2015)

Dieser Teil der ISO 12966 legt ein Verfahren zur Bestimmung von Fettsäuremethylestern (FAME), die durch Umesterung oder Veresterung von Fetten, Ölen und Fettsäuren gewonnen wurden, mittels Kapillar-gaschromatographie (GLC) fest. Durch die Anwendung dieses Teiles von ISO 12966 können Fett-säuremethylester von C8 bis C24, einschließlich gesättigte Fettsäuremethylester, einfach ungesättigte cis  und trans Fettsäuremethylester sowie mehrfach ungesättigte cis  und trans-Fettsäure¬methylester abgetrennt werden.
Das Verfahren ist geeignet für rohe, raffinierte, teilweise oder vollständig hydrierte Fette, Öle und Fettsäuren, die aus tierischen und pflanzlichen Quellen gewonnen wurden.
Dieses Verfahren ist nicht geeignet für die Untersuchung von Milch, Fetten und Ölen von Wiederkäuern, oder Produkten ergänzt mit konjugierter Linolsäure (CLA). Milch und Milcherzeugnisse (oder Fett aus Milch und Milcherzeugnissen) sind vom Anwendungsbereich dieses Teiles der ISO 12966 ausgeschlossen.
Dieser Teil der ISO 12966 ist nicht geeignet für di-, tri-, polymerisierte und oxidierte Fettsäuren und Fette und Öle.

Corps gras d'origines animale et végétale - Chromatographie en phase gazeuse des esters méthyliques d'acides gras - Partie 4: Détermination par chromatographie capillaire en phase gazeuse (ISO 12966-4:2015)

ISO 12966-4:2015 spécifie une méthode de détermination des esters méthyliques d'acides gras (EMAG) obtenus par transestérification ou estérification de corps gras et d'acide gras par chromatographie en phase gazeuse (CPG) sur colonne capillaire. Les esters méthyliques d'acides gras de C8 à C24 peuvent être séparés en utilisant la présente partie de l'ISO 12966, y compris les esters méthyliques d'acides gras saturés, les esters méthyliques d'acides gras mono-insaturés cis et trans et les esters méthyliques d'acides gras poly-insaturés cis et trans.
La méthode s'applique aux corps gras et acides gras bruts, raffinés, partiellement hydrogénés ou totalement hydrogénés d'origines animale et végétale.
La présente méthode ne convient pas à l'analyse des matières grasses laitières provenant des ruminants, ou des produits supplémentés en acide linoléique conjugué (CLA). Le lait et les produits laitiers (ou corps gras dérivés du lait et des produits laitiers) ne relèvent pas du domaine d'application de la présente partie de l'ISO 12966.
ISO 12966-4:2015 ne s'applique pas aux acides gras et corps gras dimérisés, trimérisés, polymérisés et oxydés.

Živalske in rastlinske maščobe in olja - Plinska kromatografija metilnih estrov maščobnih kislin - 4. del: Določevanje s kapilarno plinsko kromatografsko metodo (ISO 12966-4:2015)

Ta del standarda ISO 12966 določa metodo za določanje metilnih estrov maščobnih kislin (FAME), pridobljenih s transesterifikacijo ali esterifikacijo iz maščob, olj in maščobnih kislin, s kapilarno plinsko kromatografsko metodo. Metilne estre maščobnih kislin C8 do C24 je mogoče ločiti z uporabo metode iz tega dela standarda ISO 12966, vključno z metilnimi estri nasičenih maščobnih kislin, metilnimi estri cis- in trans-enkratnenasičenih maščobnih kislin in metilnimi estri cis- in trans-večkratnenasičenih maščobnih kislin.
Ta metoda velja za surove, rafinirane in delno ali povsem hidrogenirane maščobe, olja in maščobne kisline, pridobljene iz živalskih in rastlinskih virov. Ta metoda ni primerna za analizo mlečnih izdelkov, maščob in olj prežvekovalcev ali izdelkov z dodano konjugirano linolno kislino (CLA). Mleko in mlečni izdelki (ali maščoba iz mleka in mlečnih izdelkov) niso zajeti v tem delu standarda ISO 12966. Ta del standarda ISO 12966 ne velja za dimerne, trimerne, polimerne in oksidirane maščobne kisline.

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).
