What is the application process for IECEx certification? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
IECEx Member States' certification bodies recognized and authorized by the IECEx system are referred to as IECEx Accepted Application Bodies (IECEx Certification Body, abbreviated as ExCB). Only ExCBs are authorized to conduct IECEx system explosion-proof product certification.
ExCB's main certification services include:
Accept IECEx certification applications
2. Organize explosion-proof testing laboratories (ExTL) to conduct explosion-proof type testing on the products applying for certification (including explosion-proof review of drawings and documents and prototype testing).
3. Review Explosion Proof Report (ExTR)
4. Conduct factory quality condition inspections for manufacturers applying for certification, compile and review the Factory Quality Condition Report (QAR).
5. Make the decision on certification.
6. Correspond with the IECEx Secretariat for the issuance of IECEx certification.
7. Conduct annual supervision for manufacturers already holding an IECEx certification.

Which certifications are the explosion-proof ATEX and IECEx certifications from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, being a specific explosion directive under the CE certification, applicable to the EU and its regions. IECEx is the International Electrotechnical Commission's certification system for explosion-proof electrical products, which is voluntary and applicable to member states of the IECEx system.
Most of the world's major economic powers are members of the IECEx system, including China.
For IECEx and ATEX certifications, ZN Testing has summarized the following distinctions:
(1) Application Scope: ATEX certification applies to the EU region, while IECEx applies to IECEx member countries.
(2) Whether mandatory, ATEX certification is mandatory, while IECEx is voluntary.
(3) Execution Standards: ATEX Certification Standards are IEC 60079 series, IECEx Certification Standards are IEC 60079 series.
(4) Explosion-proof Marking, the ATEX explosion-proof mark is more complex than the IECEx certification mark. You can see this clearly from the examples we provide.
(5) Conversion issues: Currently, ATEX certification cannot be converted into other certificates outside the EU. IECEx member states, however, recognize IECEx certificates directly or indirectly, such as Australia and New Zealand which directly recognize IECEx certificates. Other IECEx member states (like China) can convert their IECEx certificates into local explosion-proof certificates.

What's the difference between ATEX certification and CE certification?
CE certification is a mandatory certification for the EU market; all equipment and products entering the EU market must pass the relevant CE directive certification.
For instance, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to various certification directives, with the ATEX directive specifically targeting explosion-proof equipment and products.
ATEX certification can be likened to the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive applies to the EN60079 series.
Different explosion-proof types apply to various standard series.
For example, EN 60079.1 is an explosion-proof standard, EN 60079.7 is an intrinsic safety standard, EN 60079.11 is a simple safety standard, and so on.
