IEC 62321-13:2026 pdf download,Determination of certain substances in electrotechnical products – Part 13: Bisphenol A in plastics by liquid chromatography-diode array detection (LC-DAD), liquid chromatography-mass spectrometry (LC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS).
IEC 62321-13:2026 establishes analytical methods for determining free bisphenol A (BPA) in plastic materials used in electrotechnical products. Its objective is to provide a consistent and reliable procedure for laboratories assessing restricted or environmentally relevant substances in electrical and electronic equipment.
The standard describes three instrumental techniques: liquid chromatography with diode-array detection (LC-DAD), liquid chromatography–mass spectrometry (LC-MS), and liquid chromatography–tandem mass spectrometry (LC-MS/MS). It covers essential stages of analysis, including sample selection, preparation, extraction of BPA from plastics, chromatographic separation, instrument operation, calibration, identification, quantification, and quality-control evaluation. The detailed methods are presented in the annexes, together with interlaboratory and pre-interlaboratory study information supporting method performance.
The procedures have been evaluated for polycarbonate (PC), polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS), and polypropylene (PP) matrices containing free BPA at approximately 20–500 mg/kg. Laboratories should therefore confirm applicability when testing other plastic types or concentrations outside this evaluated range. The document focuses on free BPA rather than total BPA released after chemical degradation of polymers. It is intended for trained laboratory personnel familiar with chromatography, mass spectrometry, chemical handling, and normal laboratory safety practices. The standard supports comparable test results, regulatory compliance, material screening, supplier control, and environmental assessment of electrotechnical products.
