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. Please note that some of the content of this document may involve patents. Release mechanism of the present document does not assume responsibility for the identification of these patents. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau. The main drafters of this standard. Iraq male sea, Qu Li, Cao Chen, Guo Dehua, Deng Xiaojun, Zhu Jian, Sheng Yonggang, Yang Huiqin, including Ming. This standard replaces the standards previously issued as follows. --- SN 0693-1997.
