EN IEC 62321-12:2023

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 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.

Détermination de certaines substances dans les produits électroniques - Partie 12: Détermination simultanée - Biphényles polybromés, diphényléthers polybromés et phtalates dans les polymères par chromatographie en phase gazeuse-spectrométrie de masse

IEC 62321-12:2023 spécifie une méthode d’essai de référence pour le dosage simultané des polybromobiphényles, des polybromodiphényléthers et de quatre phtalates: phtalate de di-isobutyle (DIBP), phtalate de di-n-butyle (DBP), phtalate de benzylbutyle (BBP), phtalate de bis (2-éthylhexyle) (DEHP) dans les polymères de produits électrotechniques. La technique d’extraction décrite dans le présent document est l’extraction assistée par ultrasons utilisée pour l’extraction simultanée pour la préparation des échantillons. La chromatographie en phase gazeuse-spectrométrie de masse (CG-SM) est considérée comme la technique de référence pour la mesure de la détermination simultanée des analytes dans la gamme de 25 mg/kg à 2 000 mg/kg. La méthode d’essai utilisant l’extraction assistée par ultrasons suivie d’une détection GC-MS a été évaluée par les essais de polypropylène (PP), de polychlorure de vinyle (PVC), d’acrylonitrile butadiène styrène (ABS), de caoutchouc acrylate (ACM), de polystyrène (PS), de polyuréthane (PU) et de polyéthylène (PE). Le présent document a le statut de publication horizontale conformément au Guide CEI 108
