What is the IECEx certification application process? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
IECEx Member States' certification bodies recognized and authorized by the IECEx System are referred to as IECEx Certified Bodies (ExCB). Only ExCBs are authorized to conduct IECEx System explosion-proof product certification.
ExCB is primarily responsible for the following certification tasks:
1. Accept IECEx certification applications.
2. Organize explosion-proof testing laboratories (ExTL) to conduct explosion-proof type testing on the products applying for certification (including explosion-proof review of technical drawings and documents, as well as prototype testing).
3. Review Explosion Proof Report (ExTR)
4. Conduct factory quality condition inspections for manufacturers applying for certification, 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.
7. Conduct annual supervision for manufacturers already holding an IECEx certification.

What are the differences and connections between the ATEX certification system, the IECEx, and the explosion-proof certification? -- Shenzhen ZhongNuo Inspection Technology Co., Ltd.
Currently, the ATEX and IECEx standards in Europe are almost identical.
A key standard is the EN60079 series, another key standard is IEC60079
Achieve ATEX certification for sale in the EU; obtain IECEx certification.
Theoretically, it can be sold in member countries of the International Electrotechnical Commission (IEC), such as a country that is both a member of the EU and the IEC, where an IECEx certification may not be required.
Apply for ATEX only, as ATEX is a mandatory certification under the CE category.
IECEx is not a mandatory certification. Moreover, a similar situation exists 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.

ATEX Certification Validity -- Shenzhen ZhongNuo 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 it is indefinitely valid?
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 passes.
If the factory inspection is not conducted according to schedule, the certificate will become invalid. If the certification standards are updated and the certificate is not renewed, it will also become invalid.

What documents are required to apply for IECEx certification? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
