GB 31604.26-2016 Translated English of Chinese Standard. GB31604.26-2016: National Food Safety Standard - Food contact materials and products - Determination of epichlorohydrin and determination of migrationThis standard is applicable to the determination of epichlorohydrin in food contact materials and products (plastics, paints, paper and cardboard) and the determination of the migration of epichlorohydrin. The high performance liquid chromatography (HPLC) is suitable for the determination of epichlorohydrin in food contact materials and products (plastics, coatings, paper products). The gas chromatography-mass spectrometry is suitable for the determination of the migration of epichlorohydrin in food contact materials and products (plastics, coatings, paper and cardboard). |
