标准范围

IEC 62321-10:20 20规定了一种测定电工产品聚合物中多环芳烃(PAH)的标准技术。这些多环芳烃尤其存在于各种消费品的塑料和橡胶部件中。它们作为杂质存在于用于生产此类制品的一些原料中，特别是存在于增量油和炭黑中。它们不是有意添加到制品中的，并且不作为塑料或橡胶部件的成分执行任何特定功能。气相色谱-质谱（GC MS）测试方法适用于多环芳烃（PAHs）的测定。这些测试方法已被评估用于塑料和橡胶。这些测试方法已被评估用于含有37.2毫克/千克至119毫克/千克单个多环芳烃的ABS（丙烯腈丁二烯苯乙烯）和含有1毫克/千克至221.2毫克/千克单个多环芳烃的橡胶。警告-本文件并不旨在解决与其使用相关的所有安全问题（如果有）。本文件用户有责任在使用前建立适当的安全和健康实践并确定法规限制的适用性。本横向标准主要供技术委员会根据IEC指南108中规定的原则编制标准时使用。技术委员会的职责之一是在适用的情况下，在编写其出版物时利用横向标准。除非相关出版物中特别提及或包含，否则本横向标准的内容将不适用。

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.
