ActiveDetermination of certain substances in electrical and electronic products—Part 3-3：Screening polybrominated biphenyls, polybrominated diphenyl ethers and phthalates in polymers by gas chromatography-mass spectrometry using a pyrolyser/thermal desorption accessory (Py/TD-GC-MS)
电子电气产品中某些物质的测定 第3-3部分：配有热裂解/热脱附的气相色谱-质谱法 （Py/TD-GC-MS）筛选聚合物中的多溴联苯、多溴二苯醚和邻苯二甲酸酯
Application Summary AI generated
This standard specifies a screening method using pyrolysis/thermal desorption gas chromatography-mass spectrometry (Py/TD-GC-MS) to detect polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), and phthalates in polymer materials. It is applied in the electrical and electronic products industry for rapid compliance testing of plastic components, such as casings, cables, and connectors, against hazardous substance restrictions like RoHS. The method enables efficient preliminary screening without extensive sample preparation, supporting quality control and regulatory verification in manufacturing and supply chain management.
