The ATEX 2014/34/EU directive harmonises the regulations of the member states for devices and protective systems for the intended use in potentially explosive atmospheres. It regulates the placing on the EU market of electrical and non-electrical equipment and protective systems and is directed at manufacturers and / or importers.
This directive applies:
a) Equipment and protective systems intended for use in potentially explosive atmospheres,
(b) safety, control and regulation devices for use outside potentially explosive atmospheres, but which are required or contribute to the safe operation of equipment and protective systems with respect to explosion risks;
c) Components (U-mark in the certificate, no CE marking) intended for installation in the equipment and protective systems referred to (a).
