This standard replaces the determination of cadmium in GB/T 5009.62-2003 Method for analysis of hygienic standard of ceramics for food containers, GB/T 5009.63-2003 Method for analysis of hygienic standard of enamel for food containers, GB/T 5009.72-2003 Method for analysis of hygienic standard of aluminum-wares for food use, GB/T 5009.81-2003, Method for analysis of hygienic standard of stainless steel food containers and table wares, GB/T 3534-2002 Standard testing methods for lead and cadmium release from domestic ceramic, GB 8058-2003 Standard permissible limits and testing method for release of lead or cadmium from ceramic cookware, GB/T 21170-2007 Glass hollowware - Test method for lead and cadmium release, SN/T 2597-2010 Food contact materials - Polymer materials - Determination migration amount of lead, cadmium, chromium, cadmium, cadmium and germanium - Inductively coupled plasma atomic emission spectrometry method, 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 and SN/T 2886-2011 Food contact materials for export - Glasswork - Determination of lead and cadmium in food simulants - Flame atomic absorption spectrometry (FAAS).

As compared to GB/T 5009.62-2003, key changes of this standard are as follows:

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

——the graphite furnace atomic absorption spectrometry has been added;

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

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

——the dithizone colorimetry has been deleted.
