This Part of this European Standard specifies test methods for the determination of the overall migration into fattyfood simulants from plastics materials and articles, by total immersion of test specimens in a fatty food simulant attemperatures from 5 C, up to and including 20 C, for selected times.This method is most suitable for plastics in the form of films and sheets, but can be applied to a wide range ofarticles or containers from which test pieces of a suitable size can be cut.The fatty food simulant used in these test methods is dewaxed sunflower oil since, unlike olive oil, remains liquid atthe lower test temperature.The test method described is applicable to most types of plastics, although there are some plastics for which it isknown not to be applicable.
