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!
Domestic explosion-proof certifications cannot be transferred to international IECEx certifications. This is because the Chinese explosion-proof certification standard GB/T3836 is essentially a direct citation of the gup ji IECEx explosion-proof certification standard (IEC60079). Therefore, possessing NEPSI certification does not allow for a direct transfer to IECEx certification.

Can ATEX certification be applied for in China? Which institutions can apply for an ATEX certification?
ATEX certification generally refers to the EU's explosion-proof certification; explosion-proof products exported to the EU region must undergo this certification.
To apply for ATEX certification, companies can seek domestic application agencies, and the testing can also be conducted domestically; however, the certification issuing body must be an EU Notified Body (NB).
Currently, commonly seen institutions include Germany's TÜV, Canada's CSA, Slovakia's TI, Italy's ECM, and France's BV, among others.
ATEX certification is divided into different certification models based on the explosion-proof grade.
Certification modes vary, as do the costs and requirements. Customers can choose according to their actual needs.
If you're looking to export explosion-proof products, you can message Shenzhen ZhongNuo Inspection Technology Co., Ltd. for a discussion on specific international explosion-proof certification requirements.

Can IECEx certification be converted to a domestic explosion-proof certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Currently, IECEx certification is driven by standards, which falls under a voluntary certification.
But the IECEx certification is highly recognized in the international market, with most IECEx member states either directly or indirectly acknowledging the IECEx certification.
If the product has obtained IECEx certification, provide an effective Testing Report (Ex Reports and Factory Quality Assurance Reports (QAR) issued by other member countries' Ex certification bodies (Ex CB) within the IECEx system).
Only a portion of the Testing is required for manufacturers from other member states holding an IEC Ex certificate to apply for their regional certification pathways.
For instance, China, as an IEC member, still requires the application of a Chinese explosion-proof certificate or coal safety certification for explosion-proof products.
This cannot be replaced by IECEx. In summary, if a country is a member of the IEC but also has its own mandatory explosion-proof certification,
It's usually mandatory to apply for your own explosion-proof certification, rather than just use an IECEx explosion-proof certification as a substitute.
Of course, at times, it is possible to use the already obtained IECEx Report (additional test items may be required).
To convert into a domestic mandatory explosion-proof certification, but it is essential to pass the confirmation and review by the application authority.
