电工产品中某些物质的测定 - 第10部分:气相色谱 - 质谱（GC-MS）在聚合物和电子学中的多环芳烃（PAHs）

[中文适用范围]： IEC 62321-10 规定了一种测定电气产品聚合物中多环芳烃 (PAHs) 的规范性技术。这些 PAHs 尤其存在于各类消费品的塑料和橡胶部件中。它们作为杂质存在于生产此类产品的某些原材料中，特别是增容油和炭黑中。它们不是有意添加到产品中，也不作为塑料或橡胶部件的组分执行任何特定功能。气相色谱 - 质谱法 (GC-MS) 测试方法适用于测定多环芳烃 (PAHs)。这些测试方法已针对塑料和橡胶进行评估。这些测试方法已针对含有单个 PAHs 从 37,2 mg/kg 到 119 mg/kg 的 ABS (丙烯腈丁二烯苯乙烯) 以及含有单个 PAHs 从 1 mg/kg 到 221,2 mg/kg 的橡胶进行评估。 [外文原描述]： IEC 62321-10:2020 specifies one normative technique for the determination of polycyclic aromatic hydrocarbons (PAHs) in polymers of electrotechnical products. These PAHs can especially be found in the plastic and rubber parts of a wide range of consumer articles. They are present as impurities in some of the raw materials used in the production of such articles, in particular in extender oils and in carbon black. They are not added intentionally to the articles and do not perform any specific function as constituents of the plastic or rubber parts. The gas chromatography-mass spectrometry (GC MS) test method is suitable for the determination of polycyclic aromatic hydrocarbons (PAHs). These test methods have been evaluated for use with plastics and rubbers. These test methods have been evaluated for use with ABS (acrylonitrile butadiene styrene) containing individual PAHs ranging from 37,2 mg;kg to 119 mg;kg and rubbers containing individual PAHs ranging from 1 mg;kg to 221,2 mg;kg.
