Materials and articles in contact with foodstuffs - Plastics - Part 5: Test methods for overall migration into aqueous food simulants by cell

Asnjë informacion i shtuar.

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, into aqueous based food simulants, by exposure in a standard cell for 10 days, 24 h or 2 h at 40 °C or for 2 h at 70 °C. This method is most suitable for plastics in the form of films and sheets, but is particularly applicable to those materials consisting of more than one layer or of surfaces that differ in their migration characteristics,...
