Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0639-1997 "export of meat and meat products linuron residues in."
This standard compared with SN 0639-1997, the main technical changes are as follows.
--- Change the standard name, increasing the measured metabolites;
--- Expanding the scope of application of the matrix;
--- Remove the sampling part;
--- Change to gas chromatography liquid chromatography - mass spectrometry/mass spectrometry, lower detection limit.
