Foreword
This standard replaces the determination of lead and its migration amount 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 5009.78-2003 “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”, 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 “Determination of lead, cadmium, chromium, arsenic, antimony, germanium migration quantity in polymer for food contact materials - Inductively coupled plasma atomic emission spectrometry method”, 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”, SN/T 2886-2011 “Food contact materials for export - Glasswork - Determination of lead and cadmium in food simulant - Flame atomic absorption spectrometry (FAAS)”, and SN/T 2594-2010 “Food contact materials - Determination of lead, cadmium, chromium, and arsenic in cork stoppers by inductively coupled plasma mass spectrometry”.
Compared with GB/T 5009.62-2003, 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 lead and its migration amount”
——the determination of lead has been added;
——the graphite furnace atomic absorption spectrometry has been added;
——the inductively coupled plasma mass spectrometry has been added
——inductively coupled plasma atomic emission spectrometry has been added;
——the dithizone colorimetry has been deleted.
