Do I need an ATEX certification if I already have an IECEx certificate? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
If you are exporting explosion-proof products to Europe, you will need to apply for ATEX certification.
IECEx certification is the standard certification issued by the International Electrotechnical Commission (IEC) for electrical equipment used in explosive environments.
ATEX certification is the EU standard certification for the use of electrical equipment in explosive environments.
They fall under different certifications; one cannot replace the other.

Which certifications are the ATEX certification and IECEx certification from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, part of the CE certification's explosion protection directive, applicable to the EU and its regions.
IECEx is the International Electrotechnical Commission's explosion-proof electrical products certification system, which is voluntary and applicable to member countries of the IECEx system.
Most of the major economic powers globally are members of the IECEx system, including China.
In relation to IECEx and ATEX certifications, ZN Testing summarizes the following distinctions:
(1) Application Scope: ATEX certification is applicable to the EU region, while IECEx 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 markings are more complex than the IECEx certification markings. You can see this clearly by looking at the examples we provide.
(5) Conversion issues: Currently, ATEX certification cannot be converted to other certificates outside the EU. IECEx member states recognize IECEx certificates directly or indirectly, such as Australia and New Zealand, which directly recognize IECEx certificates. Other IECEx member states (such as China) can convert their IECEx certificates into local explosion-proof certificates.

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 hazard 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 the explosion-proof certification of their respective regions.
For instance, China is also a member of the IECEx system.
However, China has its own explosion-proof certification system, which follows the standard GB/T3836.
So products with IECEx certification still need to be converted to domestic explosion-proof certification before they can be used.
