Materials and articles in contact with foodstuffs - Plastics - Part 4: Test methods for overall migration into olive oil by cell
This part of this European Prestandard describes test methods for the determination of the overall migration from one surface only of plastics in the form of sheet and film, which are intended to come into contact with fatty foodstuffs by exposure to olive oil in a standard cell or equivalent cell for 10 days, 24 h or 2 h at 40 °C or for 2 h at 70 °C. This method is most suitable for plastics in the form of films and sheets, but is particularly applicable to those materials consisting of more than one layer or of surfaces that differ in their migration characteristics,...
Werkstoffe und Gegenstände in Kontakt mit Lebensmitteln - Kunststoffe - Teil 4: Prüfverfahren für die Gesamtmigration in Olivenöl mittels Zelle
1 Anwendungsbereich
Dieser Teil dieser Europäischen Norm beschreibt Prüfverfahren für die Bestimmung der Gesamtmigration in fettige Prüflebensmittel aus nur einer Oberfläche von Kunststoffplatten oder -folien bei Temperaturen von über 20 °C bis zu, aber nicht einschließlich, 100 °C innerhalb ausgewählter Zeiten.
Dieses Verfahren eignet sich am besten für Kunststoffe in Form von Platten und Folien, ist jedoch speziell auf solche Materialien anwendbar, die aus mehr als einer Schicht oder Oberfläche bestehen, die sich in ihren Migrationseigenschaften unterscheiden, wobei nur die Oberfläche mit dem Prüflebensmittel zu prüfen ist, die für das In-Kontakt-Kommen mit Lebensmitteln vorgesehen ist.
ANMERKUNG Dieses Verfahren wurde für die Verwendung von Olivenöl als fettiges Prüflebensmittel geschrieben. Das Prüfverfahren kann auch bei geeigneten Modifikationen mit "anderen fettigen Prüflebensmitteln", genannt Prüflebensmittel D, angewendet werden, einer künstlichen Mischung von Triglyceriden, Sonnenblumenöl und Maiskeimöl. Diese anderen fettigen Prüflebensmittel werden Chromatogramme der Methylester von den Prüflebensmitteln ergeben, die sich von denen der Methylester von Olivenöl unterscheiden. Für die quantitative Bestimmung des von den Prüfmustern extrahierten Prüflebensmittels sind geeignete Chromatogramm-Peaks der Methylester von anderen fettigen Prüflebensmitteln auszuwählen.
Das beschriebene Prüfverfahren ist auf die meisten Kunststoffsorten anwendbar, obgleich es einige Kunststoffe gibt, für die es bekanntermaßen nicht anwendbar ist.
Matériaux et objets en contact avec les denrées alimentaires - Matière plastique - Partie 4: Méthodes d'essai pour la migration globale dans l'huile d'olive en cellule
La présente partie de cette norme européenne spécifie une méthode d'essai de vérification de la migration globale de plastiques dont une seule face est destinée à entrer en contact avec des simulants gras à des températures supérieures à 20 °C mais inférieures à 100 °C pendant des durées définies.
Cette méthode est généralement applicable aux plastiques sous forme de films et de feuilles, mais plus particulièrement aux matériaux composés de plusieurs couches ou surfaces ayant des migrations différentes, qui doivent être essayés avec des simulants en contact uniquement avec la surface destinée à entrer en contact avec les denrées alimentaires.
NOTE La présente méthode d'essai a été écrite pour l'huile d'olive. Elle peut également être utilisée, avec les modifications qui s'imposent pour d'autres simulants gras appelés du terme générique « simulant D », mélange synthétique de triglycérides, d'huile de tournesol et d'huile de maïs. Ces autres simulants gras donneront des chromatogrammes des esters méthyliques du simulant utilisé différents de ceux des esters méthyliques de l'huile d'olive. Choisir pour le dosage quantitatif du simulant extrait des éprouvettes les pics de chromatogramme correspondant aux esters méthyliques des autres simulants gras.
La méthode d'essai décrite est applicable à la plupart des types de plastiques, bien qu'il soit connu qu'elle ne le soit pas à certains.

Further Directives andamendments to existing Directives are expected which could change the legislative requirements which thisstandard supports.
It is therefore strongly recommended that users of this standard refer to the latest relevantpublished Directive(s) before commencement of any of the test or tests described in this standard.EN 1186-4 should be read in conjunction with EN 1186-1.Further Parts of this standard have been prepared concerned with the determination of overall migration fromplastics materials into food simulants.

The test method can also be usedwith appropriate modifications with 'other fatty food simulants ' called simulant D - a synthetic mixture of triglycerides, sunfloweroil and corn oil.
These other fatty food simulants will produce different chromatograms for the simulant methyl esters to those ofthe methyl esters of olive oil.
Select suitable chromatogram peaks of the methyl esters of the other fatty food simulants for thequantitative determination of the simulant extracted from the test specimens.The test method described is applicable to most types of plastics, although there are some plastics for which it isknown not to be applicable.2 Normative referencesThis European Standard incorporates by dated and undated reference, provisions from other publications.

Methylation is carried out by reacting a borontrifluoride/methanol complex with fatty acids formed by hydrolysing the oil with potassium hydroxide.
An internalstandard, triheptadecanoin, is added prior to the extraction of the absorbed olive oil from the test specimens.
Thisensures that any active or extractable components of the plastics react with the internal standard, as well as withthe extracted olive oil. The internal standard is also subjected to the hydrolysis and methylation reactions, providingcompensation for any inefficiencies in the hydrolysis and methylation processes.Migration into the olive oil is calculated by subtracting the mass of olive oil retained by the test specimen from theSIST EN 1186-4:2002
If an unacceptable amount of interference is present thensuitability of one of the 'other fatty food simulants' should be examined, see annex A and 9.3 and 9.5 of EN 1186-1:2002.
If aninterference is present which would interfere with the triheptadecanoin internal standard an alternative internal standard shouldbe used, see annex A, and 9.3 of EN 1186-1:2002.4 ReagentsNOTEAll reagents should be of recognized analytical quality, unless otherwise specified.4.1Olive oil, reference simulant D, as specified in 5.2 of EN 1186-1:2002.4.2Extraction solvent (see 10.1 of EN 1186-1:2002).4.2.1For non-polar plastics, such as polyethylene and polypropylene:- Pentane 98 % boiling point 36 °C.For polar plastics, such as polyamide and polyacetal:- 95/5 by volume azeotropic mixture of pentane 98 % and ethanol 99 %.NOTE 1Pentane is a very volatile and highly flammable solvent.
