Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0605-1996 "cereals for export double oxacillin alcohol residues in bacteria."
This standard compared with SN 0605-1996, the main technical changes are as follows.
--- Change the standard name;
--- Remove the sampling part;
Change --- Gas chromatography is liquid chromatography - mass spectrometry/mass spectrometry, lower detection limit;
--- Modify the pre-treatment methods.
