7. IEC: Hazardous Area Standards

IEC: Hazardous Area Standards (The Global Concept of Industrial Safety)

HISTORY

On 15 September 1904, delegates to the International Electrical Congress, being held in St. Louis, USA, adopted a report that included the following words:
“…steps should be taken to secure the co-operation of the technical societies of the world, by the appointment of a representative Commission to consider the question of the standardization of the nomenclature and ratings of electrical apparatus and machinery.” (http://www.iec.ch/about/history/overview/)

As a result, the IEC was officially founded in June 1906, in London, England, where its Central Office was set up.

Technical Committee No. 31(established in JULY, 1948) is responsible for IEC 60079 Series of Standards & Specifications

The complete team consists of :-
1. Technical Committee : TC 31 Equipment for explosive atmospheres
2. Sub-Committee : SC 31 G Intrinsically-safe apparatus
3. Sub-Committee : SC 31 J Classification of Hazardous Areas and installation requirements
4. Sub-Committee : SC 31 M Non-electrical equipment and protective systems for explosive atmospheres
