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.
