ATEX Certification Validity -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
ATEX or IECEx certificates are different from the domestic explosion-proof certification (both the domestic explosion-proof certification and the explosion-proof CCC certificate have a validity period of 5 years).
The certificate does not indicate 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 will become invalid immediately.
If the standards for certification are updated and the certificate is not renewed, the certificate will also become invalid.

What are ATEX certification and IECEx certification?
ATEX is the EU's防爆指令 under the CE certification, and all explosion-proof products used in explosive hazardous areas in the EU market must obtain ATEX certification.
It is mandatory; the certification standards are the EN60079 series.
IECEx certification is an international explosion-proof certification applicable to member countries of the IECEx system. Some member countries directly recognize the IECEx certification.
For instance, New Zealand and Australia; some member states can convert their IECEx certification to local explosion-proof certifications.
For instance, China is also a member of the IECEx system.
But China has its own explosion-proof certification system, adhering to the standard GB/T3836.
Therefore, products with IECEx certification still need to obtain domestic explosion-proof certification before they can be used.

Explosion-proof electrical products, also known as Ex products, must obtain explosion-proof certification before they can be used in hazardous explosive areas.
To eliminate unnecessary duplicate inspections and certifications of Ex products across international borders.
The International Electrotechnical Commission's防爆电气产品Certification System, abbreviated as IECEx, was formally established in 1996 to promote international trade.

What is ATEX certification and IECEx certification? What are their uses?
ATEX is the EU's防爆指令 under the CE certification, and all explosion-proof products used in explosive hazardous areas in the EU market must obtain ATEX certification.

IECEx certification is an international explosion-proof certification applicable to member countries of the IECEx system. Some member countries directly recognize the IECEx certification.
For instance, New Zealand and Australia; some member states can convert IECEx certification to their regional explosion-proof certification.
For instance, China, as a member of the IECEx system, also has its own explosion-proof certification system.
The standard implemented is GB/T3836; therefore, products with IECEx certification still need to obtain domestic explosion-proof certification before they can be marketed.
