Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces SN 0127-1992 "export milk and dairy BHC and DDT residues in", SN 0128-1992 "Export eggs and egg products BHC and DDT residues in", SN 0129-1992 "export of aquatic BHC and DDT Residue testing methods ", SN 0130-1992" bee export of BHC, DDT residues in. " This standard integration SN/T 0127, SN/T 0128, SN/T 0129 and SN/T 0130 and other industry standards. This standard compared with SN 0127-1992, SN 0128-1992, SN 0129-1992 and SN 0130-1992, major technological changes as follows. --- Extend the scope of the standard detection matrix; --- Improved sample preparation techniques; Alternative gas chromatography mass spectrometry, and use negative chemical ionization (GC-MS/NCI) Technical Verification - --- by gas chromatography. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Jiangsu Entry-Exit Inspection and Quarantine Bureau. Drafters of this standard.
