ATEX – Explosive Atmosphere


The new Directive ATEX 2014/34/EU was approved on 26 February 2014 by the European Union and repealed the previous Directive 94/9/EC.
The Directive harmonises the legislation of member states with regards to equipment and protection systems intended to be used in a potentially explosive atmosphere.
The scope of application of Directive 2014/34/EU, as well as the preceding 94/9/EC, concerns the design and construction of equipment and protection systems intended to be used in a potentially explosive atmosphere, regulates the safety requirements of said equipment and systems and defines the criteria that guarantee their free circulation on the market.

Since 20 April 2016 all equipment, protection systems, safety, monitoring and regulation devices, even if installed in safe area, and assemblies installed in a potentially explosive atmosphere must bear the CE Marking.

The new Directive has no substantial changes and reiterates the manufacturer’s responsibility for the design and construction and for preparing the technical file proving compliance of the product with the essential safety requirements, indicates the end user as the person responsible for identifying the “zones” classified “with explosion hazard” and for choosing the most appropriate equipment for the areas of use as well as the procedure to assess product compliance with the Directive.
The assessment by a notified body – where required – is the condition for the product’s Declaration of conformity to the Directive and affixing the CE marking.

ICIM is notified body No. 0425  with authorisation issued by the Ministry for Economic Development.
