Our test laboratory performs accredited testing according to DIN EN ISO 16189 for the quantitative determination of N,N-dimethylacetamide (DMAC) in footwear materials and footwear components. The standard describes an analytical method for determining solvent residues in materials and components used in footwear production. DMAC is particularly used as a polar aprotic solvent in the manufacture of polyurethane (PU) coatings, artificial leather, polymer films, and adhesive systems and may remain as a residual solvent in coated or polymer-containing materials.
Test Procedure
For the test, the sample material is prepared under defined conditions and extracted using suitable solvents. Quantitative determination of the DMAC content is subsequently carried out by instrumental analytical methods. The standardized procedure enables reproducible and sensitive determination of solvent residues even in complex material composites and PU-containing materials.
The test is applied particularly to the control of PU-coated upper materials, artificial leather, synthetic footwear materials, coatings, polymer films, adhesive systems, and other footwear components. It is used for quality monitoring, supplier evaluation, and the assessment of critical substances within product safety requirements and restricted substance lists (RSLs). N,N-dimethylacetamide is subject to restrictions and exposure-related requirements under the European REACH regulation, making the analytical control of DMAC residues increasingly important.
