Selection of Ex equipment and design of Ex installations

Manufacturers producing new Ex equipment in accordance with their Ex equipment certification regime cannot be held responsible for the decisions taken in the suitable selection of Ex equipment and the design of Ex installations required during the whole life cycle of the plant.

The IECEx Certified Service Facilities Scheme provides Ex equipment and Ex installations users, regulators and the community with the confidence that the proper selection of Ex equipment and design of Ex installations are performed by an IECEx certified service facility in accordance with this scheme.

Ex service facilities for the selection of Ex equipment and design of Ex installations that achieve IECEx certification are required to demonstrate compliance with stringent IECEx requirements including:

• Operational procedures, selection of Ex equipment, and design of Ex installations methods and criteria that meet IECEx technical requirements encompassing IEC 60079-14
• IECEx Quality Management System (QMS) requirements based on ISO 9001

• Competent responsible persons and operatives (designers) with current competencies related to Ex equipment and Ex selection and design Standards or certification requirements encompassing IEC 60079-14 and Unit of Competency Ex 009 set forth in IECEx OD 504

• Others necessary for proper selection of Ex equipment and design of Ex installations

Applying for "Part 2" service facility certification

Ex service facilities involved in the selection of Ex equipment and design of Ex installations can apply to ExCBs for service facility certification.  At present, there are no U.S. ExCBs approved to provide this "Part 2" service.
