Marking in accordance with Directive 2014/34/EU and EN standards

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
