This Part of this European Standard specifies test methods for the determination of the overall migration into fatty food simulants from one surface only of plastics in the form of film or sheet, which is intended to come into contact with foodstuffs, by forming the plastics film or sheet into standard pouches and exposing them by filling at temperatures above 20 °C and up to, but not including, 100 °C for selected times. A standard pouch is a pouch with dimensions as defined in 6.3. This method is most suitable for plastics in the form of films and sheets, which are sealable by heat or pressure, but it is particularly applicable to those materials consisting of more than one layer, which has to be tested with the food simulant in contact only with the surface which is intended to come into contact with the foodstuffs. The test method described is applicable to most types of plastics, although there are some plastics for which it is known not to be applicable.
