The IECEx System is the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. The
U.S. National Committee for the IECEx (USNC/IECEx) is the U.S. Member Body for the IECEx System. The USNC/IECEx represents all US stakeholders, and coordinates its activities with the other IEC Conformity Assessment Systems in the U.S. by actively
participating in the USNC/IEC Council and the USNC Conformity Assessment Policy Coordination Committee (CAPCC). The purpose of CAPCC is to develop and coordinate USNC/IEC positions on IEC Conformity Assessment Board (IEC CAB) issues and other
International, Regional or National Conformity Assessment agendas that may impact IEC Conformity Assessment System’s activities or interests within the U.S.
Objectives
The principal objective of the USNC/IECEx is to:
- Serve as the U.S. Member Body of the IECEx System for conformity testing and certification of electrical equipment used in explosive atmospheres.
- Coordinate with U.S. Ex Certification Bodies (ExCBs) to assure that National Differences to Ex Standards for safety that are accepted for use in the IECEx System are uniform for all ExCBs in the United States.
- Process applications for submission to the Secretariat of the IECEx System.
- Develop U.S. viewpoints and comments on all matters pertaining to the IECEx System.
- Provide a structure which is open to all related industry stakeholders.
The principle objective of the IECEx System is to facilitate international trade by providing a global framework for impartial third-party conformity assessment and certification of equipment, services, personnel and other related activities,
eoncompassing the concept of mutual recognition, while maintaining the required level of safety, including:
- Reduced testing and certification costs to manufacturer
- Reduced time to market
- International confidence in the product assessment process
- One international database listing
- Maintaining international confidence in equipment and services covered by IECEx Certification
Educational initiatives
In addition to the principal objectives of the USNC/IECEx as detailed above, our committee is involved in educational initiatives regarding the IECEx System. These initiatives
involve symposiums, presentations, papers and articles in association with organizations interested in international hazardous locations (explosive atmospheres) issues. These USNC/IECEx educational initiatives complement those by the IECEx System,
such as this recent video.
Membership
Membership in the USNC/IECEx is open to all U.S. National interested parties who are directly and materially affected by the committee's activity. Participation is fair and equitable without dominance by any single interest. All U.S. ExCBs are Members
of the USNC/IECEx.

Anyone interested in becoming a Member, including testing and certification bodies, shall make a request in writing to the USNC/IECEx Secretary stating why they believe their organization is directly and materially affected by the committee's activities.
Regarding IECEx System membership, it is by country, with there being
36 Member Body Countries as of June 2021.
IECEx System certification schemes
The IECEx System comprises the following four certification schemes:
Ex Equipment manufacturers, Ex Service providers and Ex Personnel can apply to ExCBs in the United States for certification under any of these four certification schemes. The current U.S. ExCBs under these schemes are:
- FM Approvals LLC: Certified Equipment Scheme (ExCB/ExTL)
- Intertek Testing Services NA, Inc.: Certified Equipment Scheme (ExCB/ExTL)
- UL LLC: Certified Equipment Scheme (ExCB/ExTL), Certified Service Facilities Scheme (ExCB), Certificate
of Personnel Competence Scheme (ExCB), and Conformity Mark Licensing System Scheme (ExCB)
