电气设备中某些材料的确定 第13部分：使用二极管阵列检测器的高效液相色谱（LC-DAD）、液相色谱 质谱（LC-MS）和液相色谱.. 测定塑料中的双酚 A

IEC 62321-13:2026 specifies three techniques for the determination of free Bisphenol A (BPA) in plastics of electrotechnical products. This document describes the use of liquid chromatography–diode array detector (LC-DAD), liquid chromatography mass spectrometry (LC-MS), liquid chromatography tandem mass spectrometry (LC-MS/MS) with these test methods detailed in Annex A and Annex B. These test methods have been evaluated for use with PC, PC/ABS, PP matrices containing free BPA between 20 mg/kg to 500 mg/kg as shown in the Pre-IIS 13 results in Annex C and IIS 13 results in Annex D. The use of these methods for BPA concentration ranges of plastics, other than those specified in Annex C and Annex D, has not been evaluated.
