This European Standard specifies two alternative test methods, in the sense of an extraction test with a 'moresevere' test character, for the assessment of the overall migration into fatty food simulants.Method A is based on the determination of the extraction of migrateable substances from plastics which areintended to come into contact with foodstuffs, by total immersion in non-polar, iso-octane, and/or polar, ethanol,solvents depending on the polarity of the packaging material. According to results obtained by this method (see[1], [2], [3], [4], [5]) and taking physio-chemical considerations into account, the obtained extraction efficiency has,generally, been found to be equivalent to or higher than overall migration results obtained under the test conditions,10 days at 40 °C, 2 h at 70 °C, 1 h at 100 °C, 30 min at 121 °C and 30 min at 130 °C.To ensure as complete as possible extraction of the potential migrants, a strong interaction, e.g. swelling, of thesample by the extraction solvent is necessary. For this purpose, iso-octane is used as an extraction solvent forplastics materials and articles containing non polar food contact layers, such as polyolefins. For test samples madefrom polar food contact plastics such as polyamide and polyethylene terephthalate, 95 % (v/v) aqueous ethanol isused. For polystyrenes, plasticized polyvinyl chloride and other polymers where the identification or polarity of thepolymer is not clear, two parallel extraction tests should be conducted using both of the proposed extractionsolvents and taking the higher value obtained as the relevant result.
