Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0172-1992 "food for export Staphylococcus aureus test methods."
This standard compared with SN 0172-1992, the main technical changes are as follows.
--- The original standard name "food for export Staphylococcus aureus test methods" to "import and export food Staphylococcus aureus
Testing method".
--- The original scope of the standard revised to read. "This standard applies to imported and exported food Staphylococcus aureus test";
--- Increasing the pH meter in the instrument and equipment, scales, homogenizer and adds slap slap-style homogenizer speed test sample preparation
And time.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Tianjin Entry-Exit Inspection and Quarantine Bureau, People's Republic of China Shandong Entry-Exit Inspection and
