GB 11662-2012Health protection zone for sintering industry (English PDF)

Foreword

4.2 to 4.4 of this standard are recommended, the rest are mandatory.

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

This standard replaces GB 11662-1989 "from the sintering plant health protection standards", compared with GB 11662-1989 major technological changes as follows.

--- Adjust the standard name, and according to GB/T 1.1-2009 standard structure adjustment;

--- Amendments to the definition of health protection distance, increasing the sensitive area, complex terrain, firing three terms and definitions;

--- Revised the Health protection zone standard limits;

--- Increased requirements for greening.

This standard is proposed and administered by the People's Republic of China Ministry of Health.

The standard by the China Center for Disease Control Environmental Health and Related Product Safety, Medical College of Wuhan University of Science and Technology is responsible for drafting.

1 Scope

This standard specifies the health protection distance required between businesses and sintering sensitive areas.

This standard applies to new construction, renovation, expansion project is located in the plains of sintering enterprises. Existing companies may refer to sintering.

3 Terms and Definitions

The following terms and definitions apply to this document.

Health protection healthprotectionzone Factors adversely department (workshop or workplace) to the sensitive border zone boundary minimum distance.

Sensitive area Residential areas, schools, hospitals and other air pollution sensitive areas.

Complex terrain complicatedlandform Mountains, hills, coastal.

Sintering

The powder compacts or powder which is heated to below the melting point of the main component, and to certain methods and speed of the cooling to room temperature, Thereby effect bonding between the particles, increasing the strength of the sintered body.
