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 3.
This section drafted in accordance with GB/T 1.1-2009 given rules.
