电工产品中某些物质的测定.第12部分:同时测定.用气相色谱-质谱法测定聚合物中的多溴联苯、多溴二苯醚和邻苯二甲酸酯

[中文适用范围]： 本部分IEC 62321规定了同时测定电子电气产品聚合物中多溴联苯、多溴二苯醚和四种邻苯二甲酸酯（DIBP、DBP、BBP、DEHP）的参考测试方法。 本文档描述的提取技术是用于样品制备的同时提取的超声辅助提取。 气相色谱-质谱（GC-MS）被认为是测量范围内分析物同时测定的参考技术，范围为25 mg/kg至2000 mg/kg。 使用超声辅助提取后接GC-MS检测的测试方法已通过聚丙烯（PP）、聚氯乙烯（PVC）、丙烯腈-丁二烯-苯乙烯（ABS）、丙烯酸酯橡胶（ACM）、聚苯乙烯（PS）、聚氨酯（PU）和聚乙烯（PE）材料的测试评估。 本文件根据IEC指南108具有水平标准的地位。 [外文原描述]： IEC 62321-12:2023 specifies a reference test method for the simultaneous determination of polybrominated biphenyls, polybrominated diphenyl ethers, and four phthalates: di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP) in polymers of electrotechnical products. The extraction technique described in this document is the ultrasonic-assisted extraction used for simultaneous extraction for sample preparation. Gas chromatography-mass spectrometry (GC-MS) is considered as the reference technique for the measurement of the simultaneous determination of analytes in the range of 25 mg;kg to 2 000 mg;kg. The test method using ultrasonic-assisted extraction followed by GC-MS detection has been evaluated by the tests of polypropylene (PP), polyvinylchloride (PVC), acrylonitrile butadiene styrene (ABS), acrylate rubber (ACM), polystyrene (PS), polyurethane (PU) and polyethylene (PE) materials. This document has the status of a horizontal publication in accordance with IEC Guide 108.
