This standard replaces GB/[3]18-91 "Analysis method for hygienic standard of polycarbonate resin used as food containers andpackagingmalerials". The main adjustments of this standard and Gn/18118-01 are as follows: According to the preparation rules of G3/T20001.420018 standard Part 1, the chemical analysis method has a different structure from the standard. This standard was proposed and approved by the Health Ministry of the People's Republic of China. The standard was drafted by Shanghai Food Hygiene Inspection Institute. The main contributors to the standard are: 1 Standard

4.1.4 Special determination
Filter the solution after 1 day of decomposition with qualitative saturated paper, wash with the same kind of wave to a certain density, transfer to a constant amount of Fe3 solution, cool in a water bath at 15°C, weigh, and then dry in a refrigerator at 15°C. Take out the solution and put it in a cold place for 3 hours. At the same time, do a short test. 4. 1.5 Calculate the content of the compound in mg by X=(m/m)x10g. The mass of the extracted sample is in g (). The mass of the empty sample is in g (). 4.2 Consumption of manganese dioxide After water extraction, the test sample shall be processed according to Chapter 1 of GB/T533.60-203. 4.3 Gold (in Ph) After acid extraction, the test piece shall be processed according to GB/T533.50-2003. 4.4 Acid-free sample shall be processed according to GB/T533.17.1 of 221.
