Footwear - Critical substances potentially present in footwear and footwear components - Test method to quantitatively determine dimethylformamide in footwear materials (ISO/TS 16189:2013); German version CEN ISO/TS 16189:2013
Schuhe - Möglicherweise in Schuhen und Schuhbestandteilen vorhandene kritische Substanzen - Prüfverfahren zur quantitativen Bestimmung von Dimethylformamid in Schuhwerkstoffen (ISO/TS 16189:2013); Deutsche Fassung CEN ISO/TS 16189:2013
This Technical Specification specifies a method to determine the amounts of dimethylformamide (DMFo) in footwear and footwear components containing polyurethane (PU) coated material. The sample is cut into small pieces and extracted with methanol in a sealed vial at 70 °C in an ultrasonic bath. An aliquot of the extract is analysed with GC-MS in SIM mode. This DIN SPEC is directed at footwear manufacturers and independent test laboratories. The committee responsible for this DIN SPEC is NA 062-04-52 AA "Schuhe" ("Footwear") at DIN.
