This International standard specifies three techniques for the determination of free Bisphenol A (BPA) in plastics of electrotechnical products.
The liquid chromatography – diode array detector (LC-DAD) and liquid chromatography mass spectrometry (LC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS). These test methods are described in the normative part of this standard. 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 131 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, Annex D has not been evaluated.
