EN 1186-9 Plastic Materials in Contact with Foodstuffs - Part 9: Test Methods for General Migration into Aqueous Food Equivalents by Stuffing

EUROLAB laboratory provides testing and compliance services within the scope of EN 1186-9 standard. This part of the EN 1186 standard specifies test methods for determining the total migration of container-shaped plastic articles intended to come into contact with foodstuffs from only one surface to aqueous-based food simulants by filling the articles with a liquid. Selected food simulation is used at test temperatures up to (inclusive) 70 °C for selected test times. This method is most suitable for plastics in the form of refillable containers and objects.

The overall migration of non-volatile substances from a plastic sample is determined as the mass of the non-volatile residue after evaporation of the food simulants after filling the test sample.

Test specimens are filled with food simulant for exposure time at temperatures above (inclusive) 70 °C. At the end of the test period, each test sample is emptied. The food simulant from each test sample is evaporated to dryness, the mass of the non-volatile residue determined, and expressed in milligrams per square decimeter of surface area exposed to the food simulant.

In some cases, the procedure described in this standard can be used for exposure at temperatures above 70 °C. Overall migration is reported as the average of three determinations on individual test samples.

It is important that test specimens are clean and free of surface contamination (many plastics can easily attract dust due to static charges). Before preparing test specimens, remove all surface contamination from the specimen by lightly wiping the specimen with a lint-free cloth or brushing it with a soft brush. Under no circumstances should you wash the sample with water or solvent. If it is stated in the instructions for use of the product that it must be washed or cleaned before use, refer to EN 1186-1. Cotton gloves should be worn when necessary to minimize handling of samples.
