SN/T 4209-2015Inspection rules for import and export dangerous chemical products. Ammonia (English PDF)

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 Beijing Entry-Exit Inspection and Quarantine Bureau.

Introduction

Ammonia at normal temperature and pressure (101.3kPa, 21.1 °C) under a colorless gas with a strong pungent odor. At 20 °C, 891kPa, gas State to liquefied ammonia, and release a lot of heat. Ammonia is a colorless liquid with a strong pungent odor. Ammonia can be below -77.7 °C Curing become colorless crystals having odor. Ammonia is an important industrial raw material, widely used in chemical, light industry, chemical fertilizer, pharmaceutical industries, Used as refrigerants, may also be used in the production of ammonia, ammonium salts, nitrate, synthetic fibers, plastics, dyes and the like. The main industrial use of ammonia into nitrogen and hydrogen production Direct synthesis of high temperature and pressure and in the presence of a catalyst. Ammonia main origin of Shandong, Shanxi, Henan and Hubei, the main importing countries Australia Australian, Indonesia, Egypt and Qatar.

United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" will be classified as Class 2.3 toxic ammonia gas subsidiary risk of Class 8 Corrosion, the use of pressure vessels transport UN number 1005. Ammonia human eye, nose and throat irritation and other effects, the light appeared in tears, Sore throat, cough rinse, expectoration, and conjunctiva, nasal, pharyngeal edema; severe pulmonary edema can occur, severe cough, respiratory distress, faint Fans, shock, laryngeal edema and bronchial mucosa or necrotic asphyxiation; high concentrations of ammonia can cause reflex respiratory arrest. Ammonia can cause Eye burns, skin burns. Ammonia flammable, mixed with air can form explosive mixtures case of fire, high-heat combustion caused the explosion.

In March 2011 the State Council issued the "dangerous chemical safety regulations" [591 State Council Decree] 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.

Import and export of dangerous chemicals inspection of ammonia 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

This standard specifies the import and export of hazardous chemicals ammonia, and packaging requirements, testing, qualified judgment and disposition.
