ATEX Certification Validity -- Shenzhen ZN Testing Technology Co., Ltd.
ATEX or IECEx certificates are different from domestic explosion-proof certificates (both the domestic explosion-proof certificate and the explosion-proof CCC certificate are valid for 5 years).
The certificate doesn't indicate an expiration date; does this imply that the certificate is valid indefinitely?
ATEX certificates do not have an expiration date. ATEX certification involves a combination of product testing and factory audits.
The validity of the certificate is maintained after each factory audit and approval.
If the factory audit is not conducted according to schedule, the certificate will become invalid. If the certification standards are updated but the certificate is not, it will also become invalid.

Which certifications are the ATEX certification and the IECEx certification from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, serving as a specific explosion protection 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 of the world's major economic powers are members of the IECEx system, including China.
For IECEx and ATEX certifications, China Nu Inspection summarizes the following distinctions:
(1) Scope of Application, ATEX certification applies to the EU region, 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 mark. You can clearly see this by looking at our examples.
(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.
