DIN EN 1186-15:2002-12

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 the overall migration into fatty food simulants. Method A is based on the determination of the extraction of migrateable substances from plastics which are intended 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. Method B is applicable in those cases where the total immersion test, EN 1186-15 Method 15A, yields total extraction values that exceed the overall migration or may be technically unsuitable, i.e. in the case of multilayer structures, such as plastics laminates and co-extruded films.
