Foreword

SN/T 1504 "food containers, plastic packaging materials" is divided into five parts. --- Part 1. polypropylene homopolymer phenolic antioxidants and erucamide slip agent liquid chromatography method for the determination; --- Part 2. linear low density polyethylene phenolic antioxidants and erucamide slip agent liquid chromatography method for the determination; --- Part 3. ethylene polymers and ethylene - vinyl acetate (EVA) copolymer butyl - hydroxy toluene (BHT) measured gas Chromatography; --- Part 4. High density polyethylene phenolic antioxidants was measured by liquid chromatography; --- Part 5. Polyolefin Determination of impurity elements in the X-ray fluorescence spectrometry. This section SN/T 1504 Part 1. This section drafted in accordance with GB/T 1.1-2009 given rules. The partial replacement of SN/T 1504.1-2005 "food packaging plastic container materials - Part 1. polypropylene homopolymer phenolic antioxidant Erucamide slip agent and method for measuring liquid chromatography ", this section compared with the SN/T 1504.1-2005, the main differences are as follows. Text --- this section in accordance with GB/T 1.1-2009 write; --- 4.5 filter plate pore size from the original 0.45μm to "pore size 0.45μm or less"; --- Increased 4.5 annotations; --- 5.6 10μL injection volume is changed from "10μL, or based on liquid chromatography systems appropriate to reduce the injection volume." The partial modification using ASTMD6042. Content 2009, where the title changed to "food containers, packaging material polypropylene plastic Homopolymer of phenolic antioxidants and erucamide slip agent liquid chromatography method for the determination. " This section proposed and managed by the National Certification and Accreditation Administration Committee. This section is drafted. Tianjin People's Republic of China Exit Inspection and Quarantine. The main drafters of this section. From Liu Shao, Lu Gang, Ding Yu, Yang Jing, Wang Na, Zhang Bin. This part of the standard replaces the previous editions are. --- SN/T 1504.1-2005.
