ATEX certification for explosion-proof equipment assemblies
The importance and challenges of achieving compliance for explosion-proof equipment assemblies
Explosion-proof equipment assemblies have a significant share in the explosion-proof products market and are challenging for assemblers due to the following reasons:
1- The variety of explosion protections available in the sub-assembly equipments;
2- The possibility of the sub-assembly equipment being located in different hazard zones at the installation and operation site of the assembly;
3- Determining the ATEX marking of the assembly in terms of its structure difference from the typical structure of the marking of explosion-proof equipment;
4- Collecting certificates and D.o.Cs for the equipment used in the assembly, given that the equipment, components and protective systems assembled in an assembly must all have a valid ATEX or IECEx certificate;
5- Collecting the technical file of the sub-assembly equipment in full, given that the equipment is manufactured by different manufacturers and in some cases the sub-assembly equipment are purchased from intermediary sellers;
6- Identifying and eliminating possible ignition situations (risks) in the assembly that may arise after the sub-assembly equipment is assembled.
