Materials and articles in contact with foodstuffs - Plastics - Part 2: Test methods for overall migration into olive oil by total immersion
This part of this European Prestandard describes test methods for the determination of the overall migration from plastics intended to come into contact with a fatty foodstuff, by total immersion in olive oil for 10 days, 24 h or for 2 h at 40 °C or 2 h at 70 °C. This method is most suitable for plastics in the form of films and sheets, but can be applied to a wide range of articles or containers from which test pieces of a suitable size can be cut. The test method described is applicable to most types of plastics, althoug there are some plastics for which it is known not to be applicable.
Werkstoffe und Gegenstände in Kontakt mit Lebensmitteln - Kunststoffe - Teil 2: Prüfverfahren für die Gesamtmigration in Olivenöl durch völliges Eintauchen
1 Anwendungsbereich
Dieser Teil der Europäischen Norm beschreibt Prüfverfahren zur Bestimmung der Gesamtmigration aus Werkstoffe und Gegenständen aus Kunststoff in Simulanzlösemittel für fetthaltige Lebensmittel durch völliges Eintauchen der Prüfmuster in das Simulanzlösemittel bei Temperaturen über 20°C bis zu (jedoch nicht einschließlich) 100°C während bestimmter Zeiten.
Dieses Verfahren ist bestens geeignet für Kunststoffe in Form von Folien und Platten, kann aber auch angewendet werden für einen weiten Bereich von Gegenständen und Behältern, aus denen Prüfabschnitte geeigneter Größe geschnitten werden können.
ANMERKUNG Dieses Prüfverfahren wurde beschrieben für die Verwendung von Olivenöl als Simulanzlösemittel für fetthaltige Lebensmittel. Das Prüfverfahren kann mit entsprechender Modifikation auch mit ¿anderen Simulanzlösemitteln für fetthaltige Lebensmittel" angewendet werden, dem sogenannten Simulanzlösemittel D - einer synthetischen Mischung von Triglyceriden, Sonnenblumenöl und Maiskeimöl. Diese anderen Simulanzlösemittel für fetthaltige Lebensmittel ergeben für ihre Methylester andere Chromatogramme als für die Methylester des Simulanzlösemittels Olivenöl. Aus den Chromatogrammen der Methylester der anderen Simulanzlösemittel werden geeignete Peaks zur quantitativen Bestimmung des aus dem Prüfmuster extrahierten Simulanzlösemittels ausgewählt.
Das beschriebene Prüfverfahren kann auf die meisten Kunststoffsorten angewendet werden. Es gibt jedoch einige Kunststoffe, von denen bekannt ist, dass es nicht angewendet werden kann.
Matériaux et objets en contact avec les denrées alimentaires - Matière plastique - Partie 2: Méthodes d'essai pour la migration globale dans l'huile d'olive par immersion totale
La présente partie de cette norme européenne décrit une méthode d'essai de vérification de la migration globale des matériaux et objets en matière plastique destinés à entrer en contact avec une denrée alimentaire grasse, par immersion totale d'éprouvettes dans un simulant gras à des températures supérieures à 20 °C mais inférieures à 100 °C pendant des durées définies.
Cette méthode est plus particulièrement applicable aux matières plastiques sous forme de films et de feuilles, mais peut être aussi appliquée à une large gamme d'objets ou de récipients à partir desquels des morceaux de taille appropriée peuvent être prélevés.
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 matières 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 1186-2 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.Their titles are as follows:EN 1186 Materials and articles in contact with foodstuffs - Plastics –Part 1Guide to the selection of conditions and test methods for overall migrationPart 3Test methods for overall migration into aqueous food simulants by total immersionPart 4Test methods for overall migration into olive oil by cellPart 5Test methods for overall migration into aqueous food simulants by cellPart 6Test methods for overall migration into olive oil using a pouchPart 7Test methods for overall migration into aqueous food simulants using a pouchPart 8Test methods for overall migration into olive oil by article fillingPart 9Test methods for overall migration into aqueous food simulants by article fillingPart 10Test methods for overall migration into olive oil (modified method for use in cases whereincomplete extraction of olive oil occurs)Part 11Test methods for overall migration into mixtures of

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.

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.
