This part of this European Prestandard describes a method of test for the determination of the overall migration from one surface only of plastics in the form of sheet and film, which are intended to come into contact with foodstuffs, by forming the plastics film or sheet into standard pouches and exposure to the aqueous food simulant for 10 days, 24 h or 2 h at 40 °C or for 2 h at 70 °C. A standard pouch is a pouch with the dimensions as described in 6.2. This method is most suitable for plastics in the form of films and sheets which are sealable by heat or pressure.
