Part 3-3 of IEC 62321 specifies the screening and semi-quantitative analysis of polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), di-isononyl phthalate (DINP), and di-isodecyl phthalate (DIDP) in polymers of electrotechnical products using the analytical technique of gas chromatography-mass spectrometry using a pyrolyzer/thermal desorption accessory. (Py/TD-GC-MS). This test method has been evaluated by the test of PP (polypropylene), PS (polystyrene), and PVC (polyvinyl chloride) materials containing the analyte in the range of 100 mg/kg to 1 000 mg/kg. Use of the methods described in this document for other polymer types, PBBs (mono-deca), PBDEs (mono-deca) and the phthalates or concentration ranges other than those specified above has not been specifically evaluated.
