EN IEC 62321-9:2021

Determination of certain substances in electrotechnical products - Part 9: Hexabromocyclododecane in polymers by chromatography-mass spectrometry (GC-MS)

This part of IEC 62321 specifies two techniques for the determination of hexabromocyclododecane (HBCDD) in polymers of electrotechnical products. The gas chromatography-mass spectrometry (GC-MS) test method is described in the normative part of this document. The GC-MS method is suitable for the determination of hexabromocyclododecane (HBCDD). A method using high-pressure liquid chromatography-mass spectrometry (HPLC-MS) is given in informative Annex A. These test methods have been evaluated for use with EPS (expanded polystyrene foam), XPS (extruded polystyrene foam) and ABS (acrylonitrile butadiene styrene) within the concentration ranges as specified in Table 1. The use of this method for other types of materials or concentration ranges outside those specified below has not been evaluated. [Table 1] This document has the status of a horizontal standard in accordance with IEC Guide 108.

Détermination de certaines substances dans les produits électrotechniques - Partie 9: Hexabromocyclododécane dans les polymères par chromatographie en phase gazeuse-spectrométrie de masse (GC-MS)

L'IEC 62321-9:2021 spécifie deux techniques pour la détermination de l’hexabromocyclododécane (HBCDD) dans les polymères des produits électrotechniques. La méthode d’essai par chromatographie en phase gazeuse-spectrométrie de masse (GC-MS) est décrite dans la partie normative du présent document. La méthode GC-MS convient à la détermination de l’hexabromocyclododécane (HBCDD). L’Annexe A informative spécifie une méthode utilisant la chromatographie en phase liquide sous haute pression-spectrométrie de masse (HPLC-MS). Ces méthodes d’essai ont été évaluées pour une utilisation avec une mousse EPS (polystyrène expansé), XPS (polystyrène extrudé) et de l’ABS (acrylonitrile-butadiène-styrène) dans les plages de concentrations spécifiées. L’utilisation de ces méthodes pour d’autres types de matériaux ou des plages de concentrations en dehors de celles spécifiées ci-dessous n’a pas été évaluée. Le présent document a le statut d'une norme horizontale conformément au Guide IEC 108.
