EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1186-15 testing. This European standard specifies two alternative test methods in the sense of an extraction test with a 'more severe' test character for the assessment of overall migration to fatty food simulants.
Method A is based on the determination of the extraction of transportable substances from plastics intended to come into contact with foodstuffs, by total immersion in solvents such as non-polar, iso-octane or polar, ethanol, depending on polarity.
According to the results obtained with this method and taking into account the physico-chemical aspects, it was found that the obtained extraction yield was generally as follows. Equivalent to overall migration results obtained under test conditions 40 days at 10°C, 70 hours at 2°C, 100 hour at 1°C, 121 minutes at 30°C, and 130 minutes at 30°C or higher than these.
A strong interaction with the extraction solvent, such as swelling, is required to ensure as complete extraction of potential migrant as possible. For this purpose, iso-octane is used as an extraction solvent for plastic materials and articles containing non-polar food contact layers such as polyolefins.
95% (v/v) aqueous ethanol is used for test samples made from polar plastics that come into contact with food, such as polyamide and polyethylene terephthalate. For polystyrenes, plasticized polyvinyl chloride and other polymers where the identity or polarity of the polymer is unclear, two parallel extraction tests should be performed using both recommended extraction solvents and taking the higher value obtained as the relevant result.
