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. For dated reference, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendment) applies.
