What test projects are required to apply for an explosion-proof certificate?
Explosive-proof products require passing relevant testing requirements of the explosive-proof standards to obtain an explosive-proof certification.
Different explosion-proof types, catering to equipment used in various explosive environments, require different explosion-proof testing items.
Many customers also want to know what types of tests are required for explosion-proof products?
What are the specific requirements for the explosion-proof design of the product? Let's first take a look at some common explosion-proof test items.
For example, with intrinsically safe products, general test items include appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, etc.
Explosion-proof products primarily undergo tests including heat and cold resistance, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, and more. Different testing items,
Each testing item is designed to ensure that different modules or components of the product meet the explosion-proof standards and fulfill the requirements for explosion-proof performance.
If a company is designing explosion-proof products without understanding 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 essentials, drawing guidance, and we can also handle explosion-proof testing and certification services.

What are the requirements for IECEx certification applications? -- Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
IECEx is an international certification, and there are several ExCB and ExTLs in China as well.
It's widely known that the process for applying for IECEx certification is quite complex, and the normal certification cycle takes about 5-6 months.
During the certification process, various certification documents and technical files must be provided and modified. Many companies have indicated they cannot accommodate this.
So there are also numerous IECEx certified agents in the market, such as Shenzhen Zhongnu Inspection Technology Co., Ltd.
We are familiar with the product standards of IECEx certification (IEC 60079 series) and the system standards (ISO 80079-34).
Familiar with the entire, available certified document samples and technical files.
We can also assist with the initial explosion-proof design and rectification, as well as provide factory explosion-proof system training for corporate clients.
To ensure the company applies for IECEx certification.

The ATEX certification directive encompasses several certification models:
(1) Mode A: Internal production control.
(2) B Mode: EC Type Testing. Document Review + Product Testing
(3) C Mode: Conforms to type. A method of quality assurance, with annual sampling inspections
(4) D Mode: Explosion-proof system certification. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34-2011 (EN 13980)
(5) E-Mode: Product Quality Assurance System. Factory explosion-proof system audit, includes annual review, EN ISO-IEC 80079-34-2011 (EN 13980)
(6) F Mode: Product Verification. A method of quality assurance, verifying each batch of goods before export.
(7) G Mode: Unit Certification. Single batch certification for a specific product
