Class I electrical equipment does not adhere to a specific grading system.

For Class II electrical equipment, classification is determined by the type of flammable gas encountered. This equipment is further categorized into three explosion-proof types: আইআইএ, আইআইবি, এবং আইআইসি.

In environments utilizing Class I electrical equipment, where combustible gases other than methane are present, compliance with both Class I and Class II explosion-proof standards is mandatory.

Based on the specific properties of the বিস্ফোরক dust environment, Class III electrical equipment is segmented into three categories: IIIA, IIIB, and IIIC.
