New Marking – EPL's (Explosion Protection Levels)

The introduction of the EPL's and changes in the EN 60079 and EN 61241 series standards has introduced new marking requirements.

Gas (Surface)

The gas group that was previously (II) for increased safety in surface applications is now IIA, IIB or IIC, depending upon the certification.

Dust

Grouping has also been applied to dusts where the marking is differentiated from gases by the addition of another I i.e. IIIA, IIIB or IIIC.

Explosion Protection Levels

The explosion protection levels are identified by their lettering:-

Gases Typical Zone Dusts Typical Zone
Ga 0 Da 20
Gb 1 Db 21
Gc 2 Dc 22

The protection by enclosure symbol ExtD is now being replaced by Exta, Extb or Extc.
