Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0159-1992 "fruit for export aldrin, dieldrin, heptachlor residues in."
This standard compared with SN 0159-1992, in addition to editorial changes outside the main technical amendments are as follows;
--- Modify the standard name; the "test method" to "measured"; the name of increased "BHC", "DDT", "GC";
--- Standard Scope adds orange, apple;
--- Original standard "2 sampling and sample preparation" to "6 Sample preparation and preservation";
--- Modify the original sample before standard processing methods; the column to commodity SPE column (TPT);
--- Original criteria used to fill the column capillary column.
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.
