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 international explosion-proof certification factory audit system and can provide reference materials, preliminary explosion-proof technology, and factory inspections for certification. We offer robust support for the export certification of enterprises' explosion-proof products!
Can ATEX certification be used directly in China? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
ATEX certification is valid in all EU member states, but it does not serve as a permit for selling explosion-proof products within 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, products that have passed the ATEX certification can enhance their competitiveness.
ATEX certification and explosion-proof certification share many similar standards, such as the extensive adoption of IECEx certification standards.
If the product has passed the ATEX certification, it is helpful for applying for the domestic explosion-proof certification.
Of course, domestic explosion-proof products typically undergo explosion-proof certification first before considering export, followed by ATEX certification.

What documents are required to apply for IECEx certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.

Which certifications are the explosion-proof ATEX and IECEx certifications from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, which is a directive for explosion-proofing under the CE certification, applicable to the EU and its regions. IECEx is an international certification system for explosion-proof electrical products by the International Electrotechnical Commission, voluntary in nature, and applicable to member states of the IECEx system.
Most major economic powers internationally are members of the IECEx system, including China.
For IECEx and ATEX certifications, ZN Testing summarizes 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 marking is more complex than the IECEx certification marking. You can see it clearly by looking at the examples we have provided.
(5) Conversion issues: Currently, ATEX certification cannot be converted into other certificates outside the EU. IECEx member countries, however, recognize IECEx certificates directly or indirectly. For instance, Australia and New Zealand directly recognize IECEx certificates, while other IECEx member countries (such as China) can convert their IECEx certificates into local explosion-proof certificates.

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 and is not mandatory. It is currently not recognized by the EU or North American markets, so products entering these 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.
