Determination of certain substances in electrotechnical products - Part 12:

Simultaneous determination – Polybrominated biphenyls, polybrominated diphenyl ethers and phthalates in polymers by gas chromatography-mass spectrometry.

IEC 62321-12:2023 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 the following materials:

  • polypropylene (PP)
  • polyvinylchloride (PVC)
  • acrylonitrile butadiene styrene (ABS)
  • acrylate rubber (ACM)
  • polystyrene (PS)
  • polyurethane (PU)
  • polyethylene (PE)

This document has the status of a horizontal publication in accordance with IEC Guide 108.
