The amended Council Directive 82/711/EEC will include the test conditions for plastic materials and articles intended to come into contact with foodstuffs at high temperature. The most stringent test condition (excluding susceptor materials) will be heating of the material for 2 h at 175°C in a conventional oven. For fatty foodstuffs, olive oil (simulant D), synthetic triglycerides or sunflower oil shall be used for the test. If these simulants are found inappropriate, other simulants and conditions of time and temperature may be used. In order to perform a correct evaluation of such materials one must distinguish between volatile and non‐volatile migrants, between additives and decomposition products, and between overall and specific migration. No universally applicable simulant has been found yet which is able to provide all the data needed for evaluation. The advantages and limitations of a high temperature‐resistant simulant will be described.
