This standard was drafted. Xiamen, People's Republic of China Exit Inspection and Quarantine. The main drafters of this standard. Cai Yanping, Lai Ying, Zou Jianlong, Lin Rui, Ge Xiuxiu. Importers construction with epoxy adhesive Determination of Bisphenol A

1 Scope

This standard specifies two methods for determining the import and export building of bisphenol A epoxy resin adhesive, the method comprising a first liquid chromatography - mass spectrometry / Mass spectrometry (LC-MS/MS) method and the second high performance liquid chromatography (HPLC). Wherein the first normal liquid chromatography - mass spectrometry/mass spectrometry for the arbitration law. This standard is applicable to the determination of the import and export of bisphenol A epoxy resin adhesives in.
