Foreword


This standard replaces GB/T 5009.152-2003 “Determination of residual acrylonitrile monomer in styrene-acrylonitrile copolymers and rubber-modified acrylonitrile-butadiene-styrene resins and their products used for foods packaging”, GB/T 23296.8-2009 “Food contact materials - Polymer - Determination of acrylonitrile in food simulants - Gas chromatography” and SN/T 2197-2008 “Food contact materials - Polymer - Determination of acrylonitrile in food and food simulants - Gas chromatography”.

Compared with GB/T 5009.152-2003, the major changes of this standard are as follows:

——the name of this standard has been revised to “National food safety standard - Food contact materials and articles - Determination of acrylonitrile and migration amount thereof”;

——the gas chromatography with hydrogen flame detector has been deleted, and the gas chromatograph with nitrogen-phosphorus detector is reserved;

——the determination of migration amount of acrylonitrile in food contact materials and articles has been added.
