We can provide reference materials, preliminary explosion-proof technology, and factory inspections for certification, offering robust support for enterprises' explosion-proof product export certifications!
ATEX Certification vs. IECEx Certification -- Shenzhen Zhongnuo Inspection Technology Co., Ltd.
ATEX is a mandatory certification in the EU; all explosion-proof equipment circulating in the EU market must pass the ATEX Directive 2014/34/EC certification before it can be sold.
IECEx is a voluntary certification, not mandatory, and is not currently recognized by the EU or North American markets. Products entering these markets require re-applying for the necessary certifications.

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.
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 IECEx certification.
For instance, New Zealand and Australia; certain member states can convert IECEx certification to local explosion-proof certifications.
For instance, China, also a member of the IECEx system, has its own explosion-proof certification system.
The standard followed is GB/T3836; therefore, products with IECEx certification still need to obtain domestic explosion-proof certification before they can be marketed.
We hope we can assist you.

Where can I check the IECEx certificate? -- Shenzhen ZN Testing Technology Co., Ltd.
Many clients, after obtaining the IECEx certification, want to verify the authenticity of the certificate. The IECEx certification can be verified.
Currently, IECEx certificates can be uniformly queried on the IEC website.

What test items are required to apply for an explosion-proof certification?
Explosive-proof products must pass relevant testing requirements of the explosive-proof standards to obtain an explosive-proof certificate.
Different explosion-proof types, catering to equipment used in various explosive environments, entail different explosion-proof testing items.
Many customers also want to know what testing projects are required for explosion-proof products?
What are the specific requirements for the explosion-proof design of the product? Below, we'll first give some examples of common explosion-proof testing items.
For instance, safety-intrinsic products typically include tests such as appearance and structure inspection, spark ignition tests, dielectric strength, battery and battery pack testing, temperature rise tests, and transient energy tests, among others.
Main test items for explosion-proof products include heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc. Different testing items,
For each module or component of the product, every test item ensures that the product meets the explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products and is unaware of the explosion-proof standards requirements,
ZhongNuo Inspection can provide guidance services for explosion-proof circuit design and explosion-proof structural design.
Including explosion-proof standards, design key points, drawing guidance, and offering agency services for explosion-proof testing and certification.
