EN 16778:2016 (E) 4 1 Scope This document specifies a test method for the determination of Dimethylformamide (DMFa – CAS N° 68-12-2) in glove materials. NOTE For Dimethylformamide the following abbreviations can be used: DMF, DMFa DMFo. The test method is applicable for the following materials: — polyurethane (PU) materials (except elastane), PU Coated material (textile, leather), PU foam, PU blended materials; — adhesives; — all materials manufactured with a dipping process using DMFa. 2 Normative references Not applicable. 3 Principle The sample is cut into small pieces and extracted with methanol in a sealed flask in an ultrasonic bath. An aliquot of the extract is analysed with GC-MS. 4 Consumables 4.1 Reagents The substances are given in Table 1.
