Overall migration testing – simulant A, B, D2 (all foodstuff), repeated use

Overall migration (OML) testing with simulant A, B, and D2 (as repeated use) is used to ensure the compliance of plates, utensils, cups, appliances, lunch boxes, trays, cookware, kitchenware, and all other articles which are intended for contact with all types of foods.

Overall migration (OM) is the sum of all the non-volatile compounds that migrate from the food contact material into the food.

According to Regulation (EU) No 10/2011 materials and articles intended for contact with all types of food shall be tested with food simulants A (10% ethanol), B (3% acetic acid), and D2 (olive oil).

With aqueous simulants (i.e., simulants A and B), compliance for repeated use is determined by measuring the overall migration three consecutive times from the same sample.

Due to its destructive nature, testing for three consecutive overall migrations with simulant D2 from the same test object is not technically feasible. Hence, the test is carried out on three sets of the same sample material with varying exposure times.

In order to comply with Regulation (EU) No 10/2011, the overall migration must not exceed 10 mg/dm2 (or 60 mg/kg). In the case of repeated use articles, compliance is evaluated from the 3rd migration.
