Tests on equipment and protective systems intended to be used in potentially explosive atmospheres.The European Directive 94/9/CE, ATEX, has been acknowledged in SEE starting from July the 1st, 2003 - even if published in 1994.- This Directive applies to products, as specified below, intended to be used in potentially explosive atmospheres.When the ATEX Directive came into force, previous rules and standards on the subject were abrogated. Therefore, starting from 01/07/2003, products not in conformity with the requirements of ATEX Directive are forbidden to be put 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.
