What is ATEX?

Potentially Explosive Atmosphere

The term ATEX refers to atmospheres that are potentially explosive due to the possible presence of dusts, vapours or gases that are likely to ignite or explode.

Area Classification

The ATEX Directive 99/92/EC makes it mandatory for manufacturers to assess the explosion risk and classify the area accordingly.

Mandatory Certification

The ATEX Directive 2014/34/EC forces manufacturers to gain certification of electrical and or mechanical products that can be used in a potentially explosive atmosphere.

Certified Equipment

Once an area is classified as potentially explosive, a risk analysis will normally dictate that only electrical and mechanical equipment that is suitably certified can be used.
