For most of the substances in the table 1 there are no official and validated migration test
methods available. Taking this into account migration modelling is of great help for a first
orientation and a further selection of the most appropriate strategy of testing.
4.3
Examples
In this section the use and potential of migration modelling is demonstrated with a few
examples obtained from reference /13/. These examples are presented with the aid of a
market available software which is specifically tailored (MIGRATEST Lite 2001), according
to the requirements mentioned above and includes all the equations given in this report.
