Note: IEC 60079-0 divides equipment into three categories:
---Class I: equipment for coal mine gas environment;
---Class II: equipment for all other explosive gas atmospheres except coal mine gas atmospheres, and this type of equipment is further divided into several categories;
---Class III: Equipment for all other explosive dust atmospheres other than coal mines, and this type of equipment is divided into several categories:
426-01-04
Achievable by any part or any surface of Ex equipment when operating under the most adverse operating conditions (but within the specified tolerances)
maximum temperature:
Note 1: For Ex equipment for explosive gas atmospheres, the temperature appears on the internal components or on the outer surface of the enclosure, depending on the type of protection:
Note 2: For Ex equipment for explosive dust atmospheres, this temperature appears on the outer surface of the enclosure and includes the specified dust layer conditions:
426-01-05
temperature group temperatureclass
The method of classification based on the maximum surface temperature of Ex equipment is related to the specific explosive gas atmosphere in which the Ex equipment is intended to be used:
