Part Explanation
II: Equipment group (non mining)
h: The letter ”h” as specified in EN ISO 80079-36.
IIB: Equipment of Group II is intended for use in places with an explosive gas atmosphere
other than mines susceptible to firedamp.
Equipment of Group II is subdivided according to the nature of the explosive gas
atmosphere for which it is intended.
Group II subdivisions:
• IIA, a typical gas is propane;
• IIB, a typical gas is ethylene;
• IIC, a typical gas is hydrogen.
IIIC: Equipment of Group III is intended for use in places with an explosive dust atmosphere
other than mines susceptible to firedamp.
Equipment of Group III is subdivided according to the nature of the explosive dust
atmosphere for which it is intended.
Group III subdivisions:
• IIIA: suitable for combustible flyings;
• IIIB: suitable for combustible flyings and non-conductive dust;
• IIIC: suitable for combustible flyings, non-conductive dust and conductive dust.
T60ºC…150ºC The maximum surface temperature in degrees Celsius.
This is set as a range since it depends on the temperature of the media used.
Gb: Equipment protection level Gb. Same as old 2G marking.
For explosive atmospheres, caused by mixtures of air and gases, the equipment does not
contain any effective ignition sources in normal operation and expected malfunctions.
Db: Equipment protection level Db. Same as old 3D marking.
For explosive atmospheres, caused by mixtures of air and combustible dusts, the
equipment does not contain any effective ignition sources in normal operation and
expected malfunctions.
-10ºC≤Ta≤60ºC Ambient temperature range
