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.
Currently, there were 24 notified bodies involved in the ATEX Directive.
As of May 21, 2014, 67 European institutions have obtained authorization from the EU announcement.
Commonly compared ATEX notified bodies include TÜV Süden, 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 specific explosion directive under the CE certification, applicable to the EU and its regions. IECEx is the certification system for explosion-proof electrical products by the International Electrotechnical Commission, which is voluntary and applicable to member countries of the IECEx system.
Most major economic powers internationally are members of the IECEx system, including China.
In relation to IECEx and ATEX certifications, Zhongnuo Inspection summarizes the following distinctions:
(1) Scope of Application: ATEX certification is applicable in the EU region, while IECEx certification is applicable 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 mark. You can see this clearly from the examples we have provided.
(5) Conversion issues: Currently, ATEX certification cannot be converted to other certificates outside the EU. IECEx member states 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.
