ATEX Example Products, Tests and Standards

Explosive atmospheres scenario

Specific tests are required on equipment and protective systems intended to be used in potentially explosive atmospheres.

The European ATEX directive 2014/34/EU came into force in 2016. This Directive applies to products, as specified below, intended to be used in potentially explosive atmospheres. Products not in conformity with the requirements of the current ATEX Directive CE and Ex Mark are forbidden to be placed into the market.

  • Components, as any item essential to the safe functioning of equipment and protective systems but with no autonomous function; on these components the CE mark is forbidden, but a written attestation of conformity must be provided for each component to place it on the market;
  • Protections systems, different by components, separately placed on the market, intended to halt incipient explosions;
  • Safety devices, controlling devices and regulating devices intended for use outside potentially explosive atmospheres but required for or contributing to the safe functioning of equipment and protective systems with respect to the risks of explosion.
