This standard BS EN IEC 62321-9:2021 Determination of certain substances in electrotechnical products is classified in these ICS categories:
43.040.10 Electrical and electronic equipment
13.020.01 Environment and environmental protection in general
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.
