Shenzhen ZhongNuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal mine safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
Which certifications are the ATEX certification and IECEx certification from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, which is a防爆 directive under the CE certification, applicable to the EU and 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 major economic powers internationally are members of the IECEx system, including China.
In regards to IECEx and ATEX certifications, ZN Testing has summarized the following distinctions:
(1) Applicability: ATEX certification is applicable to the EU region, IECEx certification is applicable to IECEx member states.
(2) Whether mandatory, ATEX certification is mandatory, IECEx is voluntary.
(3) Execution Standards: ATEX certification standards are IEC 60079 series, IECEx certification standards are IEC 60079 series
(4) Explosion-proof marking, the ATEX explosion-proof marking is more complex than the IECEx certification marking. You can see it clearly by looking at the examples we have provided.
(5) Conversion issues: Currently, ATEX certification cannot be converted into certificates outside the EU. IECEx member countries, however, recognize IECEx certificates directly or indirectly, such as Australia and New Zealand, which directly recognize IECEx certificates. Other IECEx member countries (like China) can convert their IECEx certificates into local explosion-proof certificates.

Is a product's explosion-proof certification the same as its explosion-proof certificate?
Many clients inquire during consultations: What's the difference between obtaining a explosion-proof certification and a explosion-proof qualification certificate for a product?
Explosion-proof certification and explosion-proof approval certificates are two different concepts. Once a product undergoes explosion-proof certification, the resulting document is an explosion-proof approval certificate.
Ex防爆 certification is a process, Ex proof certificate is the result.
So the customer said the product needs to have a explosion-proof certification or explosion-proof compliance certificate.
The product must pass the explosion-proof standard tests and meet the standard requirements to obtain an explosion-proof certification.
Explosion-proof certifications can be categorized into intrinsic safety types, flameproof types, positive pressure types, and casting types, among others, based on different explosion-proof protection styles.
ZheNuo Inspection boasts a team of explosion-proof engineers capable of providing early-stage design services for explosion-proof circuits and structures.
Assist companies in preparing the required drawings, technical specifications, corporate standards, and other documentation for explosion-proof certification, facilitating their smooth acquisition of the explosion-proof compliance certificate.

What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to different certification directives; the ATEX directive is specifically for explosion-proof equipment and products.
ATEX certification can be considered the CE certification for explosion-proof products.
Each directive has different applicable standards; for the ATEX directive, the applicable standards are the EN60079 series.
Different explosion-proof types apply to different standard series.
For instance, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is the standard for increased safety, and EN 60079.11 is the standard for intrinsic safety, etc.
