Characterization of waste. Determination of brominated flame retardants (BFR) in solid waste Ingestion-build-48974 The PD CEN/TR 16931 series1 Scope This European Standard specifies a method for the determination of selected polybrominated flame retardants (BFR), chemically known as polybrominated diphenylethers (BDE), in waste materials using gas chromatography mass spectrometry (GC MS) in the electron impact (EI) ionisation mode (GC EI MS). When applying GC EI MS, the method is applicable to samples containing 100 g kg to 5 000 g kg of tetra to octabromodiphenylether congeners and 100 g
