1 Scope
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.
