The requirements and assessments (incl. the
marking) concerning electrical and non-electrical
“equipment and protective systems intended for
use in potentially explosive atmospheres” are
uniformly defined in Directive 2014/34/EU. The
marking of equipment and components is furthermore specified in the standards for general
technical requirements (EN 60079-0 for electrical
equipment or EN ISO 80079-36 for non-electrical
equipment).
Accordingly, the overall marking on an ATEX
equipment or component is made up of the
require-ments under Directive 2014/34/EU and the
requirements of EN standards. Both sources define
the same requirements in some areas, which leads
to redundant information on the identification label.
It is impossible to estimate whether and when this
duplicated information will be synchronized.
1. The manufacturer with name + address that has
placed the equipment on the market
2. The type designation by which the equipment
can be identified
3. The application area under ground Mining I or
other surface areas II
4. The application area for gases and vapours (G),
dusts (D) or mines (M)
5. The categories (1, 2 or 3) that state which safety
level applies and whether the equipment may be
used in certain zones
6. The type(s) of protection that the equipment
satisfies
7. The group and the sub-group that the equipment
is suitable for
8. The temperature class (G) or max. surface
temperature (D) that the equipment complies
with.
9. The equipment protection level (EPL in
accordance with EN 60079-0 and EN ISO 80079-
36) and the gases and vapours (G), dusts (D) or
mining (M) application area that state whether
the equipment may be used in certain zones
10.The specific conditions of use, where necessary,
that must be followed, recognizable to an X
either behind the certificate number (category 1
and 2) or behind the type of protection (category
3 when no voluntary Type Examination Certificate
exists)
11.The type examination certificate with the
Notified Body, the year of issue and the
registration number of the certificate at the
NoBo. for example PTB 20 ATEX 9999 X
