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 Guangxi Exit Inspection and Quarantine.

Introduction

Carbon monoxide is a colorless, odorless, non-irritating Extremely flammable gas. Solubility in water is very small, but soluble in aqueous ammonia. With air Mixed explosion limit 12.0% ~ 74.0%. Pure carbon monoxide is mainly used in the standard gas, carbon monoxide lasers, environmental monitoring and scientific research Studies in. Electronics industry for laser gas. Terminating agent used in ethylene polymerization. For the production of sodium formate, as in the metallurgical industry Reducing agent, also used in chemical synthesis, such as methanol synthesis, such as phosgene. Carbon monoxide and other major importing countries are the United States.

In accordance with the United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" classified as a Class 2.3 (toxic gas) Dangerous Goods, at the same time 2.1 times the risk of having a first class (flammable gases), the United Nations No. 1016. Council and blood hemoglobin after carbon monoxide enters the body Protein binding, causes the body to suffocation. Carbon monoxide may fertility or fetal harm.

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.

Import and export of dangerous chemicals inspection of carbon monoxide Warning. Use of this standard should have the relevant inspection or testing work experience and relevant qualifications. This standard does not indicate the There are potential security issues. Users are responsible for the use of appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.

1 Scope

This standard specifies the requirements for the import and export of carbon monoxide and its packaging, testing and conformity determination and disposal.

This standard applies to the import and export of carbon monoxide and packaging inspection.
