Familiar with the international explosion-proof certification factory audit system, we provide reference materials, preliminary explosion-proof technology, and factory inspections for certification. We offer robust support for enterprise explosion-proof product export certification!
What are ATEX certification and IECEx certification?
ATEX is the EU's CE certification for explosive atmosphere protection, and all explosion-proof products used in potentially explosive hazardous areas in the EU market must obtain ATEX certification.
It is mandatory; the certification standards are the EN60079 series.
IECEx certification is an international explosion-proof certification applicable to member countries of the IECEx system. Some member countries directly recognize the IECEx certification.
For instance, New Zealand and Australia; some member states can convert their IECEx certifications to local explosion-proof certifications.
For instance, China is also a member of the IECEx system.
However, China has its own explosion-proof certification system, which is implemented according to GB/T3836.
Therefore, products with IECEx certification still need to be converted to domestic explosion-proof certification before they can be used.

ATEX Certification and CE Certification: Relationship and Differences
CE certification is a mandatory product certification in the European Union.
Below are many directives, such as LVD, EMC, MD, RED, ATEX, etc.
Different commands apply to different categories of products.
For example, ATEX is a directive under the CE marking, applicable to explosion-proof equipment and products.
Each directive has different product certification standards. For the ATEX directive, the product certification standards are the EN60079 series.

ATEX Certification Application
The EU has restricted the issuance of ATEX certification to only authorized notified bodies within the EU to control the safety performance of explosion-proof equipment.
As of May 21, 2014, there are now 67 European bodies that have obtained EU notification authorization, up from the previous 24 notified bodies involved in the ATEX Directive.
Commonly compared ATEX notified bodies include TÜV SÜD, TÜV Nord, TÜV Rheinland, DNV, BV, QS, DEKRA, EUROFINS, UL, CSA, ECM, etc.

Which certifications are the explosion-proof ATEX and IECEx certifications from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, serving as a directive for explosion-proof within the CE certification, applicable to the EU and its regions.
IECEx is the International Electrotechnical Commission's explosion-proof electrical products certification system, which is voluntary and applicable to member countries of the IECEx scheme.
Most major economic powers globally are members of the IECEx system, including China.
In relation to IECEx and ATEX certifications, ZhongNuo Inspection summarizes the following distinctions:
(1) Application Scope: ATEX certification is applicable to the EU region, IECEx certification is applicable to IECEx member countries.
(2) Whether mandatory, ATEX certification is mandatory, while IECEx is voluntary.
(3) Standard of Execution, ATEX certification standard is IEC 60079 series, IECEx certification standard is IEC 60079 series
(4) Explosion-proof marking, the ATEX explosion-proof marking is more complex than the IECEx certification marking. You can see this clearly from the examples we provide.
(5) Conversion issues: Currently, ATEX certification cannot be converted to 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.
