IEC 62321-12:20 23规定了同时测定多溴联苯、多溴二苯醚和四种邻苯二甲酸酯的参考测试方法:邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二正丁酯(DBP)、邻苯二甲酸苄基丁酯(BBP)、电工产品聚合物中邻苯二甲酸二（2-乙基己基）酯(DEHP)。 本文中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）被认为是同时测定25 mg/kg至2 000 mg/kg范围内分析物的参考技术。 通过对聚丙烯（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，评估了使用超声波辅助萃取然后GC-MS检测的测试方法。根据IEC指南108，本文件具有横向出版物的地位。

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.
