Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

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

This standard was drafted. People's Republic of China Anhui Exit Inspection and Quarantine, Ningbo Entry-Exit Inspection and People's Republic of China Quarantine Bureau.

Introduction

Sulfur dioxide, sulfurous acid anhydride alias at room temperature is a colorless gas with a pungent odor, easily liquefied. Sulfur dioxide can dissolve in water, acetone, ethyl More solvent alcohols, formic acid, acidic aqueous solution. Liquid sulfur dioxide is a good solvent. Sulfur dioxide in the chemical industry and pharmaceutical industry Preparation for the main bisulfites such as sodium bisulfite as a paper mill bleach; converted associated bisulfite and sulfite, such as sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium bisulfite, sodium thiosulfate, preparation of sulfuryl chloride, thionyl chloride, production of gelatin and glue, used Reducing agents or solvents. At present, China's domestic production of sulfur dioxide can basically meet the demand, production capacity wide distribution.

United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" (UNRTDG) sulfur dioxide primary hazard classified as class 2.3 Toxic gases, dangerous times classified as Class 8 corrosive substances, UN number 1079. Sulfur dioxide can cause respiratory inflammation, bronchitis, lung Emphysema, conjunctivitis psychosis. While also making immunity adolescents decreased disease resistance becoming weaker. The role of sulfur dioxide in antioxidants, light Next, can generate sulfate aerosols, sulfate aerosols that can cause disease, increased patient mortality.

In March 2011 the State Council issued the "dangerous chemical safety regulations" (State Council Decree No. 591) provides for inspection and quarantine departments Responsible for the import and export of hazardous chemicals and their packaging implementation of the inspection. To ensure the effective implementation of the relevant inspection and quarantine operations, standardize import and export Dangerous chemicals and packaging inspection and supervision work, the development of this standard.

Inspection of import and export of hazardous chemicals sulfur dioxide Warning. Use of this standard should have the relevant inspection or testing work experience and relevant qualifications. This standard does not indicate all possible security issues. Users are responsible for the use of appropriate safety and health practices and to ensure compliance with relevant national regulations condition.

1 Scope
