SN/T 0502-2013Determination of toxaphene residues in aquatic products for export. GC method (English PDF)

Foreword

Accordance with the standards GB/T 1.1-2009 given rules drafted.

This standard replaces SN 0502-1995 "Fern residues in aquatic products for export poisoned." this standard compared with SN 0502-1995, in addition to editorial changes outside the main technical changes are as follows.

--- Standard name "Fern residues in aquatic products for export poisoned" by a modification of the "export of aquatic toxaphene residues measure GC set ";

--- Expand the scope of the standard detection object;

--- Deletion of a portion of the sample;

--- Improved sample preparation techniques;

--- Reducing the lower limit of detection, and detection of different objects, given the recovery of different substrates by adding different concentrations of the standard substance range.

This standard is proposed and managed by the National Certification and Accreditation Administration Committee.

This standard was drafted. People's Republic of China Shandong CIQ.
