New Practice of many ATEX Notified Bodies (which are also IECEx ExCB) is to use the elements of IECEx (ExTRs, QAR) to issue a EC Type Examination Certificate , the QA Notification and the IECEx Certificate of Conformity

7. What is IECEx?
The single International IEC System with Schemes covering Certification to Standards that relate to Equipment and Services in areas relating to Explosive Atmospheres, to provide an Internationally accepted means of demonstrating claimed compliance with International Standards
IECEx is a “Conformity Assessment Tool” providing confidence that Products, Services and Personnel covered by an IECEx Certificate meet specified requirements, (International Standards)
What is IECEx?
By the early 1990’s the various industries found that as governments were responding to the concerns of risk in the Ex field, differing national standards were being introduced along with differing certification and approval regimes meaning that if a manufacturer wished to sell a product in more than one country, the manufacturer was required to obtain approval/certification for each. This meant for many countries, the need to repeat expensive and time consuming product testing and assessment. The differing approvals processes, some with factory inspections others not and different intervals between factory inspections all meant additional costs and delays to placing products on the market.
This lead industry to request IEC to provide a forum to enable industry to develop a true international system that provided manufacturers with a single system where testing and assessment would only need to be conducted once and accepted by all members of the system while including measures that ensure operators of the system have the necessary equipment, facilities, systems and competent staff to conduct this work.
The result is IECEx, an International Certification Scheme, modelled on the strict compliance with International ISO/IEC Standards such as 17025, Guide 65 and 67.
As an ISO System No 5 Certification Scheme (according to ISO/IEC Guide 67) Compliance with the standards listed on an IECEx certificate is mandatory.
“IECEx is the International Standard way of doing Ex Certification”

The IECEx Services
While the initial scope of IECEx was the International Certification of Ex Equipment, industry soon realised that the benefits of a single International system covering testing and certification of Ex equipment could equally apply to Ex related Services, e.g. Repair and Overhaul according to IEC and to the assessment and qualification of Persons that operate in or with Ex areas.
The concerns from industry arose from the fact that all the dedication to ensuring Ex Equipment is designed and manufactured then certified as complying with an Explosion Protection Technique, according to the relevant IEC standard, all this work and effort could be in vain if the Ex equipment is not installed correctly or even, when subjected to repair and overhaul, such work compromises the original Ex design feature. Use of Repair Workshops holding an IECEx Certificate, provides industry with the confidence that Ex repair will be conducted according to IEC , as these Workshops are under constant surveillance by IECEx Certification Bodies.
Today, the vast majority of national or regional regulations incorporate systems for the testing and approval of Ex equipment alone and provide little systems to address Ex related Services or the Qualification of Ex Persons.
This prompted industry to expand the IECEx System to now provide the separate Certifications Schemes we see on this slide. In addition, industry identified the need for a dedicated IECEx Conformity Mark and licensing system that currently applies to manufacturers producing Ex products covered by IECEx certificates.
The drive behind the IECEx Services Scheme came from the knowledge that the Ex field is one of the few where in many cases the initial capital cost of Ex equipment is so high that repair and overhaul is by far a more economical option to replacement, especially for large and purpose built equipment, e.g. motors. While there are many companies worldwide offering Repair and Overhaul facilities, a centralised system to verify their compliance with IEC did not exist until IECEx launched its new IECEx Certified Services Scheme a couple of years ago.
With credible certification systems in place covering new Ex Equipment and Ex related Services, attention was drawn to the number of accidents and incidents occurring in and around Ex related installations.
One of the cause that has been clearly identified as a significant contributor to incidents in the oil and gas industry is the varying levels of knowledge and Competence and lack of a structured international system to assess and attribute competence to those working in or associated with Ex areas.
The new IECEx Certificate of Personnel Competency Scheme (CoPC) provides for the assessment of a persons knowledge, their experience and current ability to apply the knowledge. An IECEx CoPC Certificate provides clear attestation that the person is competent to apply the Standards as listed on their IECEx Certificate according the attributed Units of Competency. This Scheme is very new with IECEx currently conducting the first round of assessments of Certifiers seeking to become an IECEx Certification Body to issue IECEx CoPC Certificates. The first three Certifiers currently under assessment include Baseefa (GB), INERIS (FR) and SIRA (GB). Additional bodies such as NEMKO (NO) and KEMA (NL) are preparing for their assessments by IECEx. IECEx expects the first IECEX CoPC Certificates to be issued by mid 2010.

Solely ISO Guide 67 Type 5 certificates (with ongoing surveillance)
Use of Internet “On-Line” Systems for Certificates. Equipment, Services, Personnel
Congruent with ATEX elements
IECEx DNA
Foundation for all IEC Certification Schemes
The four foundation principles listed in this slide apply to all three IEC Conformity Assessment Systems of IECEE, IECEx, IECQ.
These principles provide for a single set of rules, procedures and forms that must be used by all Certification Bodies that participate in these Schemes. One further significant benefit is that all Certification and Test Bodies are subject to the same assessment process regardless of the country they reside or operate or whatever national accreditations they may hold.
The IEC Systems, including IECEx differ from the models used by National Accreditors in that IEC Systems such as IECEx require all Test houses and Certifiers, operating in IECEx, to conduct the testing and assessment the same way to the same procedures and same forms thus providing a greater level of consistency by all Certifiers in the Scheme. Perhaps the best description to describe IEC Systems such as IECEx is that their model aligns with that of a “Franchised Model” so that a manufacturer or an applicant applying for IECEx certification may apply to any IECEx Certifier (ExCB) and have their application processed in the same way.
IEC Systems such as IECEx do in fact support competition among the bodies but competition exists in terms of cost of certification and turnaround times. IECEx does not allow competition on the quality of the certification service offered.
Two significant benefits to industry of IEC Certification Systems are:
that each is managed and operated on a day to day basis by a dedicated Technical Secretariat, meaning that Certifiers, Test houses and industry have a single point of contact to approach on any questions concerning the IEC Scheme, via the dedicated Internet website that each maintain, and
The open and full public access to issued IEC certificates via the “On-Line” Certificate system for instant confirmation of certification status
