This standard replaces the determination of migration amounts of chromium in GB/T 5009.80-2003 “Method for analysis of hygienic standard of polytetrafluorethylene coating for inner wall of food container”, GB/T 5009.81-2003 “Method for analysis of hygienic standard of stainless steel food containers and table wares”, SN/T 2597-2010 “Determination of lead, cadmium, chromium, arsenic, antimony, germanium migration quantity in polymer for food contact materials – Inductively coupled plasma atomic emission spectrometry method” and SN/T 2829-2011 “Food contact materials for export – metal materials – Determination of migrant heavy metals in food simulant – Inductively coupled plasma atomic emission spectrometric method”.

Compared with GB/T 5009.81-2003, 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 migration amounts of chromium”;

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

——the inductively coupled plasma atomic emission spectrometric method has been added.
