Hawke Cable Glands - ATEX
ATEX is the term used when referring to the European Unions (EU) Directive 94/9/EC. The ATEX Directive main objectives are to guarantee the free circulation of goods within the European Union by aligning the technical and legal requirements of the Member States.
"ATEX" is derived from the French "Atmosphères Explosibles".
The Atex Directive is named: - "Approximation of the laws of the Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres".
The Atex Directive covers electrical and non-electrical equipment and protective systems intended for use in potentially explosive atmospheres in mining and surface industries.
The Atex Directive Covers.....
* Equipment and products that have potential ignition sources.
* Protective Systems - products that control the effects of incipient
explosions.
* Safety Devices - products that may be outside a potentially explosive
atmosphere but that have an explosion safety function.
* Components - products that are intended to form parts of equipment
or protective systems.
To ensure compliance with the Atex Directive, electrical equipment must meet with the essential requirements specified in the Directive and be marked with the CE marking.
The process of ensuring that equipment complies with the Atex Directive, conformity assessment procedure(s) must be complied with. These procedures may involve a Notified Body. A Notified body is a body that is independent of the product manufacturer and assesses conformity of the products and the manufacturer with the Directive. The Notified Body has to be approved and appointed by its government.
