1 Scope
This document 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[1], [2]. 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.
This document is a basic environment horizontal publication focusing on test methods and is primarily intended for use by committees in the preparation of publications within the area of environment in accordance with the principles laid down in IEC Guide 123. Wherever applicable, it is the responsibility of committees to make use of environment basic publications in the preparation of their environment group and product publications. Committees can apply this document directly to products when they do not develop a product publication in the area of environment.
