ATEX Directive 2014/34/EU Testing

ATEX Directive 2014/34/EU, formerly 94/9/EC
ATEX 2014/34/EU concerns equipment and protective systems intended for use in potentially Explosive Atmospheres.

F2 Labs can assist you in meeting the requirements of the ATEX standards for products intended to be used in potentially explosive atmospheres.

Before a manufacturer places equipment that could be used in an explosive atmosphere on the market, they must have their product tested to the appropriate ATEX standards under the ATEX 2014/34/EU directive, formerly 94/9/EC. The product must also meet the CE marking directive.

F2 Labs knowledgeable staff can assist manufacturers in determining the appropriate CE and ATEX standards for electrical and non-electrical equipment. Get your product to market with our expertise in 2014/34/EU, formerly 94/9/EC, ATEX testing and certification.

  • Zone 2 – An atmosphere where a mixture of air and flammable substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for only a short period.
  • Zone 20 – An atmosphere where a cloud of combustible dust in the air is present frequently, continuously or for long periods.
  • Zone 21 – An atmosphere where a cloud of combustible dust in the air is likely to occur in normal operation occasionally.
