Shenzhen ZhongNuo Testing Technology Co., Ltd. offers ATEX and IECEx certification consulting services. We are well-versed in international explosion-proof standards such as IEC 60079, EN 60079, and ISO 80079. We are familiar with the factory audit systems for international explosion-proof certification and can provide reference materials, preliminary explosion-proof technology, and factory inspections. We offer robust support for the export certification of explosion-proof products for enterprises!
Where can I check the IECEx certificate? -- Shenzhen Zhongnuo Inspection Technology Co., Ltd.
Many customers, after obtaining the IECEx certification, want to verify the authenticity of the certificate. The IECEx certification is verifiable.
Currently, IECEx certificates can be uniformly queried on the IEC website.

Which certifications are the ATEX and IECEx certifications from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, a specific explosion directive under the CE certification, applicable to the EU and its regions. IECEx is the international certification system for explosion-proof electrical products by the International Electrotechnical Commission, voluntary in nature, and applicable to member countries of the IECEx system.
Most of the world's major economic powers are members of the IECEx system, including China.
In relation to IECEx and ATEX certifications, ZN Testing has summarized the following distinctions:
(1) Application Scope: ATEX certification applies to the EU region, IECEx certification 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 Markings, the ATEX explosion-proof mark is more complex than the IECEx certification mark. You can see it clearly by looking at the examples we provide.
(5) Conversion issues: Currently, ATEX certification cannot be converted to 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.

Can ATEX certificates be used directly in China? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
ATEX certification is applicable to all EU member states but does not serve as a permit for selling explosion-proof products domestically in China.
We have our own explosion-proof certification system. Explosion-proof products sold domestically must pass our explosion-proof certification, not the ATEX certification.
However, this does not imply a lack of recognition for ATEX certification.
Instead, obtaining ATEX certification can enhance the product's competitiveness.
ATEX and explosion-proof certifications often share similar standards, such as extensively adopting the IECEx certification criteria.
If the product has passed the ATEX certification, it is beneficial for applying for the domestic explosion-proof certification.
Of course, domestic explosion-proof products typically undergo explosion-proof certification first before considering export, with ATEX certification being a subsequent consideration.
