DIN EN IEC 62321-12:2024-07

This part of the IEC 62321 standard specifies a reference test method for the 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. The extraction technique described in this document is the ultrasonic-assisted extraction used for simultaneous extraction for sample preparation. Gas chromatography-mass spectrometry (GC-MS) is considered as the reference technique for the measurement of the simultaneous determination of analytes in the range of 25 mg/kg to 2 000 mg/kg. The test method using ultrasonic-assisted extraction followed by GC-MS detection has been evaluated by the tests of polypropylene (PP), polyvinylchloride (PVC), acrylonitrile butadiene styrene (ABS), acrylate rubber (ACM), polystyrene (PS), polyurethane (PU) and polyethylene (PE) materials. This document has the status of a horizontal publication in accordance with IEC Guide 108. Persons using this document should be familiar with standard laboratory practice. This document does not claim to address all safety issues that may arise from its use. It is the responsibility of the user to take appropriate safety and health precautions and to ensure compliance with any national regulations. The use of certain substances (for example, lead (Pb), cadmium (Cd), polybrominated diphenyl ethers (PBDE), and specific phthalates) in electrical and electronic products is of concern in current and proposed legislation in many regions of the world. The purpose of the IEC 62321 series of standards is therefore to provide test methods that enable the electrical industry to determine the content of certain problematic substances in electrical products on a consistent global basis.
