Equipment assemblies and skid packages used in explosive atmospheres must receive IECEx certification for electrical and mechanical features.

IEC TS 60079-46 defines an equipment assembly as a pre-manufactured combination of Ex equipment comprising many items of equipment. These individual items are then integrated as part of the equipment assembly.

IECEx IEC/TS 60079-46 specifies requirements for the design, construction, assembly, testing, inspection, marking, and documentation of individual items that comprise the assembly.
