    Test to be performed on the final product depending on the composition of the material. The table below shows the methods used for each type of material:

    Analytical method DWD EU

    To identify the methods to use for organic materials, the products or components are classified into risk groups according to their use and a conversion factor (FC) which can be obtained from table 5 of the fourth act. The conversion factor allows the expected concentration in water to be calculated based on the results of the migration tests.

    Based on the conversion factor, the product or component is classified in a risk group (GR) in accordance with table 1 of the fourth act.

    The notified body will appoint testing laboratories which must be EN ISO/IEC 17025:2017 accredited.
