Shenzhen Zhongnuo Inspection & Technology Co., Ltd. is based in South China, specializing in explosion-proof certification and coal safety certification application consulting services, offering one-stop explosion-proof technology consulting services.
Which certifications are the explosion-proof ATEX and IECEx certifications from?
ATEX certification is a mandatory certification for explosion-proof products in the EU, a specific explosion directive under the CE certification, applicable to the EU and regions.
IECEx is the International Electrotechnical Commission's explosion-proof electrical product certification system, which is voluntary and applicable to member countries of the IECEx scheme.
Most 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 applies to the EU region, IECEx applies 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 marking, the ATEX explosion-proof marking is more complex than the IECEx certification marking. You can see the clarity from our examples.
(5) Conversion Issues: Currently, ATEX certification cannot be converted into other certificates outside the EU. IECEx member countries 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 qualification certificate?
Many customers ask during inquiries what the difference is between obtaining a explosion-proof certification and a explosion-proof qualification certificate for a product?
Flameproof certification and flameproof approval certificate are two different concepts. Once a product undergoes flameproof certification, the result is a flameproof approval certificate.
Explosion-proof certification is the process, and the explosion-proof certificate is the result.
So the customer mentioned the need for a防爆 certification or防爆 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 cast-in types, among other explosion-proof protection styles.
ZhongNuo Inspection boasts a team of explosion-proof engineers who can provide early-stage design services for explosion-proof circuits and structures.
Assist companies in preparing the required drawings, technical specifications, and manuals, as well as corporate standards, for explosion-proof certifications, facilitating their easy 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 must comply with the relevant CE directives.
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 likened to 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 are applicable to different standard series.
For example, 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.
