Our test laboratory performs accredited testing according to DIN EN ISO 16189 for the quantitative determination of N,N-dimethylformamide (DMF) in footwear materials and footwear components. The standard is intended for footwear and components made of or containing PU-coated materials. DMF may occur as a residual solvent particularly in PU-coated materials, artificial leather, coatings, and adhesive systems.
Test Procedure
For the tests, the sample material is prepared and extracted under defined conditions. The quantitative determination of the DMF content is then carried out using analytical measurement methods. The standardized procedure enables reproducible detection of residual solvents in PU-containing materials.
The test is applied to the control of PU-coated upper materials, synthetic footwear materials, artificial leather, textile coatings, and footwear components. It is relevant for supplier evaluations, incoming goods inspections, and the assessment of critical substances in footwear materials. In addition, REACH restrictions exist for N,N-dimethylformamide in substances and mixtures, while footwear products are often also subject to material-related customer specifications and restricted substance lists.
