Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces SN 0692-1997 "turpentine chloride residues in meat and meat products for export." This standard compared with SN 0692-1997, the main changes are as follows. --- Abolition of the "sampling and sample preparation," adds "Sample Preparation and Storage" (see Chapter 5, Chapter 2, 1997 edition); --- Sample extraction by the Soxhlet extraction method to extract high-speed vortex (see 61, 1997 version 3.4.1.); --- Sample purification method consists of two sulfonated gel permeation purification to purify (see 62, 1997 edition of 3.4.2 and 3.4.4.); --- Canceled the step of sample extract in methanol was added a solution of potassium hydroxide dehydrochlorination (see the 1997 version 3.4.3); --- Determination by gas chromatography to gas chromatography - mass spectrometry (see 63, 1997 edition of 3.4.5.); --- Quantitative methods limit the 0.2mg/kg amended to 0.01mg/kg (see 7.1, 4.1, 1997). 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 Hunan Exit Inspection and Quarantine. The main drafters of this standard. Li Yongjun, Fushan Liang, Wang Meiling, Yanhong Fei, Jiao Yanna, Dai Hua, Xiao Jiayong. This standard replaces the standards previously issued as follows. --- SN 0692-1997. Exports of meat and meat products turpentine chloride residues By Gas Chromatography - Mass Spectrometry
