标准范围

IEC 62321-9:20 21规定了两种测定电工产品聚合物中六溴环十二烷(HBCDD)的技术。气相色谱—质谱（GC-MS）检测方法描述于本文件的规范性部分。GC-MS法适用于六溴环十二烷（HBCDD）的测定。给出了使用高压液相色谱-质谱（HPLC-MS）的方法。这些测试方法已经在规定的浓度范围内与EPS（发泡聚苯乙烯泡沫）、XPS（挤出聚苯乙烯泡沫）和ABS（丙烯腈丁二烯苯乙烯）一起使用进行了评估。尚未评估将该方法用于以下规定之外的其他类型的材料或浓度范围。根据IEC指南108，本文件具有水平标准的地位。

IEC 62321-9:2021 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.
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. The use of this method for other types of materials or concentration ranges outside those specified below has not been evaluated.
This document has the status of a horizontal standard in accordance with IEC Guide 108.
