Standard DIN 10955 specifies test methods for the sensory analysis of food contact materials and articles that are intended for direct food contact. This analysis is performed according to the standard to determine the migration of odor and flavor from the packaging material into the food. By default, test is performed as Difference from Control-Test (DfC-Test) with a scoring scale. Test is also available as a triangle test for an additional cost.

Determination of the specific migration of elements listed in Annex II of Commission Regulation (EU) No 2020/1245 (15th amendment of the Commission Regulation (EU) No 10/2011). The test covers the following elements or parameters: Lithium (Li), Sodium (Na), Magnesium (Mg), Aluminum (Al), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As), Cadmium (Cd), Antimony (Sb), Barium (Ba), Lanthanum (La), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Mercury (Hg), Lead (Pb), Sum of lanthanides – Eu, Gd, La, Tb.

Overall migration (OML) testing with simulants A, B, and D2 is used to ensure the compliance of food packaging, cling film, freezer bags, nitrile gloves, takeaway boxes, and all other materials or articles that are intended for contact with all types of foods. Overall migration is the sum of all the non-volatile compounds that migrate from the food contact material into 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). To comply with the regulation, overall migration must not exceed 10 mg/dm2 (or 60 mg/kg). If testing with simulant D2 is not technically feasible, it is substituted with simulants D2e (95% ethanol) and D2i (isooctane). In case the contact temperature exceeds 100 °C, testing overall migration with simulant E (Tenax) is also necessary (not included in the cost). Our experts will provide guidance for selecting the appropriate simulants and migration conditions. Do not hesitate to ask for more information or a quote for testing repeated-use articles (the displayed price applies to single-use materials).

Primary aromatic amines (PAA) are a class of compounds that are generated when residual isocyanate groups in food contact materials react with the water in foods. In addition, articles in which aniline, benzidine, or other PAAs have been used as precursors for pigments or as curing agents can be a source for restricted PAA. Certain PAAs are known carcinogens, and these are listed in entry 43 to Appendix 8 of Annex XVII to Regulation (EC) No 1907/2006 of the European Parliament and Council (known as the REACH Regulation). These PAAs are not allowed to migrate into food or food simulants. Primary aromatic amine testing is especially relevant for products that contain, for example, the following: Aromatic isocyanate groups containing SML substances, Polyurethane-based materials, Azo dyes, Recycled plastic.
