Understanding ATEX Ex Marking

All ATEX-certified equipment must be clearly marked with the appropriate Ex marking to demonstrate compliance with the ATEX Directive and identify the conditions under which the equipment can be used safely in potentially explosive atmospheres.

A typical ATEX Ex marking includes information such as:

• Equipment group

• Equipment category

• Type of explosion protection

• Gas or dust classification

• Temperature class

These markings provide essential information for selecting the correct equipment for hazardous areas, helping ensure regulatory compliance, safe installation, and reliable operation.
