Do I need an ATEX certification if I already have an IECEx certificate? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
If explosion-proof products are exported to Europe, an ATEX certification must be applied for.
IECEx certification is the standard certification issued by the International Electrotechnical Commission for the use of electrical equipment in explosive environments.
ATEX certification is the European Union's standard certification for the use of electrical equipment in explosive environments.
They belong to different certifications, and one cannot replace the other.

ATEX explosion-proof certification directive has the following certification modes:
(1) Mode A: Internal Production Control
(2) B Mode: EC Type Testing. Document Review + Product Testing
(3) C Mode: Conforms to type. A method of quality assurance, with annual sampling inspections
(4) D Mode: Explosion-proof system certification. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34-2011 (EN 13980)
(5) E-Mode: Product Quality Assurance System. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34-2011 (EN 13980)
(6) F Mode: Product Verification. A method of quality assurance, where each batch of goods is verified before export.
(7) G Mode: Unit Certification. Batch certification for a specific product

ATEX Certification vs. IECEx Certification
ATEX is a mandatory certification in the EU; all explosion-proof equipment in circulation in the EU market must pass the ATEX Directive 2014/34/EC certification to be sold.
IECEx is a voluntary certification, not mandatory, and is currently not recognized by the EU or North American markets. Products entering the EU and North American markets require a new certification application.
The specific execution standards for explosion-proof certification in the North American market depend on whether the owner opts for the local Division explosion-proof system or the Zone explosion-proof system.

ExCB undertakes the following certification tasks:
1. Accept IECEx certification applications.
2. Organize explosion-proof testing laboratory (ExTL) to conduct explosion-proof type testing on the products applying for certification (including explosion-proof review of technical 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 issuance of IECEx certification.
