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 the export certification of explosion-proof products for enterprises!
What is the IECEx certification application process? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Members of the ECEx system, whose certification bodies are recognized and authorized by the IECEx system, are referred to as IECEx Accepted Application Bodies (IECEx Certification Body, abbreviated as ExCB). Only ExCBs are authorized to conduct explosion protection product certification work within the IECEx system.
ExCB is primarily responsible for the following certification tasks:
1. Accept IECEx certification applications.
2. Organize Explosion-Proof Testing Laboratory (ExTL) to conduct Explosion-Proof Type Testing for the products applying for certification (including explosion-proof review of technical drawings and documents, as well as sample machine testing).
3. Review Explosion-Proof Report (ExTR)
4. Conduct factory quality condition inspections for manufacturers applying for certification and compile and review the Factory Quality Condition Report (QAR).
5. Make the decision on certification.
6. Correspond with the IECEx Secretariat for issuance of IECEx certification certificates.
7. Conduct annual supervision for manufacturers already holding an IECEx certification.

Domestic explosion-proof certifications cannot be transferred to international IECEx certifications. This is because the GB/T3836 explosion-proof certification standards in China are essentially direct references to the gup ji IECEx explosion-proof certification standards (IEC60079). Therefore, even with NEPSI certification, it cannot be directly transferred to an IECEx certification.

What are the differences and connections between the ATEX certification system and the IECEx for explosion-proof certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Currently, the ATEX and IECEx standards in Europe are almost identical in content.
A primary standard is the EN60079 series, another primary standard is the IEC60079
Achieve ATEX, eligible for sale in the EU; obtain IECEx,
Theoretically, products can be sold in member countries of the International Electrotechnical Commission (IEC), such as those that are both EU members and IEC members, where IECEx certification may not be required.
Just apply for ATEX, as ATEX is a mandatory certification under the CE category.
IECEx is not a mandatory certification. Additionally, similar situations exist for other IEC member countries.
For instance: China, also a member of IEC,
However, explosion-proof products require a Chinese explosion-proof certification or coal safety certification, and cannot be substituted with IECEx.

Imported explosion-proof equipment now has an ATEX certification. How can it be converted to a domestic explosion-proof certification?
If the imported equipment has a valid ATEX certification, it cannot be converted to a domestic explosion-proof certification.
You must apply for the domestic explosion-proof certification or explosion-proof 3C certification according to the new product and application procedures.
