Determination of migration test temperature (SML and OM) for microwave application
Tests of specific migration (SML) and overall migration (OM) on plastic articles which are intended for use in microwave ovens,in accordance with EN 1186-1 are performed under the appropriate time and temperature conditions in a conventional oven. For this purpose the temperature that occurs at the interface of food / packaging during heating of the contents under the conditions of use in the worst foreseeable conditions must be determined. This is done by using a calibrated microwave oven at the predetermined heat output.
