标准范围

IEC 62321-3-3:20 21规定了使用热解器/热解吸附件（Py/TD-GC-MS）的气相色谱-质谱分析技术对电工产品聚合物中的多溴联苯（PBBs）、多溴联苯醚（PBDEs）、邻苯二甲酸二异丁酯（DIBP）、邻苯二甲酸二正丁酯（DBP）、邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二正辛酯（DNOP）、邻苯二甲酸二异壬酯（DINP）和邻苯二甲酸二异癸酯（DIDP）进行筛选分析。如附件J所示，通过对含有100毫克/千克至1 000毫克/千克十溴二苯醚和100毫克/千克至4 000毫克/千克邻苯二甲酸酯的PP（聚丙烯）、PS（聚苯乙烯）和PVC（聚氯乙烯）材料的分析，对该测试方法进行了评估。本文件中描述的方法用于其他聚合物类型、PBBs（mono deca）、PBDEs（mono-deca）、PBDEs（mono-deca）deca)和邻苯二甲酸盐或除上述规定之外的浓度范围尚未具体评估。根据IEC指南108，本文件具有水平标准的地位。

IEC 62321-3-3:2021 specifies the screening analysis of polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), di-isononyl phthalate (DINP), and di-isodecyl phthalate (DIDP) in polymers of electrotechnical products using the analytical technique of gas chromatography-mass spectrometry using a pyrolyser/thermal desorption accessory (Py/TD-GC-MS).
This test method has been evaluated through the analysis of PP (polypropylene), PS (polystyrene), and PVC (polyvinyl chloride) materials containing deca-BDE between 100 mg/kg and 1 000 mg/kg and individual phthalates between 100 mg/kg to 4 000 mg/kg as depicted in Annex J. Use of the methods described in this document for other polymer types, PBBs (mono deca), PBDEs (mono-deca) and phthalates or concentration ranges other than those specified above has not been specifically evaluated.
This document has the status of a horizontal standard in accordance with IEC Guide 108.
