Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0663-1997 "heptachlor and heptachlor epoxide residues in meat and meat products for export."
This standard compared with SN 0663-1997 main changes are as follows.
--- Modify the standard name. the "export of meat and meat products for heptachlor and heptachlor epoxide residues in" to "export meat and meat
Products in the heptachlor and heptachlor epoxide residues in the determination ";
--- Standard Scope increased beef, chicken, ham, sausage;
--- Original standard "2 sampling and sample preparation" to "6 Sample preparation and preservation";
--- Modify the original standard sample preparation method. the chromatography column to the commercialization of solid-phase extraction column, an increase of gel permeation chromatography (GPC)
Purification;
--- Increased by Gas Chromatography - Mass Spectrometry.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Jiangxi Exit Inspection and Quarantine.
