GB/T 39560.8-2021《电子电气产品中某些物质的测定》第8部分标准解析

Analysis of GB/T 39560.8-2021,Determination of certain substances in electrical and electronic products—Part 8:Phthalates in polymers by gas chromatography-mass spectrometry(GC-MS),gas chromatography-mass spectrometry using a pyrolyzer/thermaldesorptio

本文对新发布的GB/T 39560.8-2021《电子电气产品中某些物质的测定》第8部分:气相色谱-质谱法(GC-MS)与配有热裂解/热脱附的气相色谱-质谱法(Py/TD-GC-MS)测定聚合物中的邻苯二甲酸酯进行了标准解析。该标准使用翻译法等同采用IEC 62321-8:2017,修改了标准名称,规定了聚合物中邻苯二甲酸酯类物质测定的两种标准方法和两种参考方法。本文是对该标准中四种方法的详细解析,旨在为标准的使用提供参考。

The paper interprets the new test method of GB/T 39560.8-2021,Determination of certain substances in electrical and electronic products—Part 8:Phthalates in polymers by gas chromatography-mass spectrometry(GC-MS),gas chromatography-mass spectrometry using a pyrolyzer/thermaldesorption accessory(Py/TD-GC-MS).This standard adopts the translation method equivalent to IEC 62321-8:2017,and has a different name,specifying two standard detection methods and two reference methods of the determination of phthalates in polymer.This paper interprets the four methods in the new standard,in order to provide a reference for users.
