Foreword

This standard replaces the determination of arsenic and migration amount thereof in GB/T 5009.68-2003 Method for analysis of hygienic standard of perchlorovinyl-coating for inner wall of food container, GB/T 5009.72-2003 Method for analysis of hygienic standard of aluminum-wares for food use, GB/T 5009.78-2003 Method for analysis of hygienic standard of papers for food packaging, GB/T 5009.81-2003 Method for analysis of hygienic standard of stainless steel food containers and table wares, SN/T 2900-2011 Food contact materials for export - Paper and regenerated fibre materials - Determination of arsenic - Hydride generation-atomic fluorescence spectrometry, SN/T 2594-2010 Food contact materials - Determination of lead, cadmium, chromium and arsenic in cork stoppers - Inductively coupled plasma mass spectrometry, SN/T 2597-2010 Food contact materials - Polymer materials - Determination migration amount of lead, cadmium, chromium, arsenic, antimony and germanium and SN/T 2829-2011 Food contact materials - metal material - Determination of the content of heavy metal in food simulant - Inductively coupled plasma atomic emission spectrometry.

As compared to GB/T 5009.68-2003, key changes are as follows:

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

——the determination of arsenic has been added;

——the inductively coupled plasma mass spectrometry has been added;

——the inductively coupled plasma atomic emission spectrometry has been added;

——the silver salt method and arsenic stain method have been deleted.
