Specification of two empiric methods for the quantitative determination of the loss in mass of test specimens in presence of activated carbon under given conditions of temperature and time. They are intended for the determination of plasticiser migration from plastics which are exposed to heat. In method A the test piece is in direct contact with activated carbon, while in method B the contact is prevented by a metallic fabric. These methods are preferably used for a fast comparation of plasticised thermoplastics.
