UNE EN IEC 62321-12:2023
This part of IEC 62321 specifies one normative extraction and measurement technique for simultaneous determination of polybrominated biphenyls, polybrominated diphenyl ethers, and four phthalates (di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP)) in polymers of electrotechnical products. Ultrasonic-assisted extraction is described for simultaneous extraction for sample preparation in this document. Gas chromatography-mass spectrometry (GC-MS) is considered the normative technique for measurement of simultaneous determination of the analytes in range of 25 mg/kg to 2 000 mg/kg. This test method has been evaluated by the test of PP, PVC, ABS, ACM, PS, PU and PE materials.
