1 Scope This standard specifies the methods of testing level of polybrominatde biphenyls and polybrominatde diphenyl ethers in automotive materials. "X-ray fluorescence spectrometry" is applicable to screening and rapid judgment of bromine content in automotive materials by X-ray fluorescence spectrometry. "Gas chromatography-mass spectrometry (GC-MS) method" is applicable to determination of content of PBBs and PBDEs in automotive materials by gas chromatography - mass spectrometry. 2 Normative References The following documents for the application of this document are essential.
