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 explosion-proof products!
Imported explosion-proof equipment now has an IECEx certification. How can it be converted to a domestic explosion-proof certification?
If the imported equipment has a valid IECEx certification, it can be converted into a domestic explosion-proof certification.
Please provide the original IECEx certification Certificate and Report, as well as product drawings and other relevant documents for review by ZhongNuo Inspection.
Check if any relevant testing is needed.

IECEx certification is achieved through a process of Type Testing (product testing) + Factory Quality System Inspection + Post-Certification Surveillance.
The entire IECEx certification process spans from providing documentation, preparing samples, conducting product testing, factory audits, to issuing the certificate.

ATEX Certification Validity -- Shenzhen ZN Testing Technology Co., Ltd.
ATEX or IECEx certificates differ from domestic explosion-proof certificates (both the domestic explosion-proof certificate and the explosion-proof CCC certificate have a validity period of 5 years).
The certificate does not state an expiration date; does this imply that the certificate is valid indefinitely?
ATEX certificates do not have an expiration date. ATEX certification is 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 becomes invalid immediately.
If the certification standards are updated and the certificate is not, the certificate will also become invalid.

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 within the CE certification for explosion-proofing and is applicable to the EU and its regions.
IECEx is the International Electrotechnical Commission's certification system for explosion-proof electrical products, it 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.
In regards to IECEx and ATEX certifications, Zhongnuo Inspection summarizes the following distinctions:
(1) Application Range: 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) Execution Standards: ATEX certification standards are IEC 60079 series, IECEx certification standards are IEC 60079 series
(4) Explosion-proof Markings, the ATEX explosion-proof mark is more complex than the IECEx certification mark. You can see this clearly by looking at the examples we have provided.
(5) Conversion issues: Currently, ATEX certification cannot be converted to other certificates outside the EU. IECEx member countries recognize IECEx certificates directly or indirectly, such as Australia and New Zealand, which directly recognize IECEx certificates. Other IECEx member countries (such as China) can convert their IECEx certificates into local explosion-proof certificates.
