What is the Ex mark (Epsilon X mark)?
The Ex mark is a specific marking for explosive protection equipment. It is used to show that equipment,
protective systems or components comply with the requirements of the European standards that are harmonised
with the 94/9/EC Directive (ATEX Directive, named after the French "ATmosphere EXplosible").
The ATEX Directive 94/9/EC became mandatory on 1 July 2003 and replaced the three old Directives:
76/117/EEC, 79/196/EEC, 97/53/EEC and 83/130/EEC.
The products covered by the ATEX Directive are divided into different groups and categories. The areas
where the explosive atmospheres are present are divided into Zones, mainly based on how long and how
frequently the explosive atmosphere is present. Electrical equipment marked Category 1 may be used in
Zone 0,1 and Zone 2. Equipment marked Category 2 may be used in Zones 1 and 2. Equipment marked Category
3 may be used in Zone 2. Third party certification is mandatory for the electrical equipment that is used
in Zone 0 and Zone 1.
The ATEX Directive is a CE Marking directive, which means that products marked with the Ex mark also have
to be marked with the CE mark before they can be placed on the EU market. The technical assessment to allow
that has to be carried out by a Notified Body (appointed by the authorities in the EU Member States). UL
is a Notified Body to the ATEX Directive through UL International Demko A/S and can provide you with the
EX- certification.
