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 enterprises seeking export certification for their explosion-proof products!
What are the differences and connections between the ATEX certification system,防爆认证, and IECEx? -- Shenzhen ZhongNuo Inspection Technology Co., Ltd.
The ATEX and IECEx standards in Europe are almost identical in content at present.
A primary standard is the EN60079 series, another primary standard is IEC60079
, Obtain ATEX, sell in the EU; obtain IECEx,
Theoretically, it can be sold in member countries of the International Electrotechnical Commission (IEC), such as a country that is both a member of the European Union and the IEC, where an IECEx application may not be required.
Just apply for ATEX, as ATEX is a mandatory certification under the CE category.
IECEx is not a mandatory certification. Moreover, similar situations exist for other IEC member states.
For instance: China, also a member of IEC,
However, explosion-proof products require a Chinese explosion-proof certification or coal safety certification, and cannot be substituted with IECEx.

Which certifications are the explosion-proof 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 regions. IECEx is an international certification system for explosion-proof electrical products by the International Electrotechnical Commission, voluntary in nature, applicable to member countries of the IECEx system.
Most major economic powers globally are members of the IECEx system, including China.
For IECEx and ATEX certifications, ZN Testing summarizes the following distinctions:
(1) Scope of Application, ATEX certification applies to the EU region, IECEx certification applies to IECEx member states.
(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 it clearly in our examples.
(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.
