ATEX Directive 2014/34/EU Ex Products & Standards

ATEX Example Products, Tests and Standards

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.
