Can ODM/OEM companies apply for explosion-proof certification and explosion-proof 3C certification? What are the requirements?
Many customers are asking whether their products are OEM manufactured, ODM branded, or purchased.
Can I apply for an explosion-proof certificate or explosion-proof 3C certification?
Here, Zhongnuo Inspection introduces the requirements and conditions for applying for the explosion-proof certification and the explosion-proof 3C certification.
To apply for an explosion-proof certification, the company only needs to provide product design drawings and samples.
No requirement for a production factory.
So, whether it's an OEM, ODM, or a product purchased directly,
As long as the required drawings and samples for certification are provided, a防爆合格证 can be applied for.
Of course, the provided drawings and samples must comply with the explosion-proof certification standards.
To obtain the explosion-proof 3C certification, in addition to the explosion-proof certificate, there is a requirement for factory audit and an annual supervision and evaluation.
Therefore, the applicant must have their own manufacturing factory/OEM/ODM factory.
The application process is also more complex and the cost higher, with a longer duration, compared to obtaining the explosion-proof certification.
Zhenuo Inspection has been dedicated to the explosion-proof field for many years, well-versed in the requirements of the GB/T 3836 series standards.
Extensive experience in design and modification guidance for explosion-proof products.
Offer a one-stop service for explosion-proof certification, including design modification, drawing evaluation, certification acquisition, factory audit, and explosion-proof 3C certification consulting.
We boast a wealth of evidence collection cases and experience. Feel free to send us a private message!

The Difference Between Applying for an Explosion-Proof Certificate and an Explosion-Proof 3C Certification:
This should be for products under the explosion-proof 3C catalog, such as motors, fans, intercoms, etc., all of which fall under the explosion-proof 3C catalog.
Previous applicants for explosion-proof certification need to convert to the explosion-proof 3C certification.
The application for explosion-proof 3C certification adopts the "Product Testing + Factory Audit" approach.
The requirement is that the applicant must have a manufacturing factory or an OEM/ODM factory.
Products not listed in the explosion-proof 3C certification catalog only require an explosion-proof qualification certificate.

What test items are required to apply for an explosion-proof certificate?
Explosion-proof products must pass relevant testing requirements of the explosion-proof standards to apply for an explosion-proof certificate.
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 testing projects are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Next, let's take a look at some common explosion-proof testing items.
For instance, with intrinsic safety products, the general test items typically include appearance and structure inspection, spark ignition tests, dielectric strength, battery and battery pack testing, temperature rise tests, and transient energy tests, etc.
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, tailored to different modules or components of the product.
Each test item ensures that the product meets 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 essentials, drawing guidance, and offering explosion-proof testing and certification consulting services.

List of Domestic Explosion-Proof Certification Institutions:
1. Nanyang CNEX
2. Shanghai Coal Research Institute
3. National Electrical Appliances Quality Supervision and Inspection Center
4. Guangdong CQCEx National Explosion-Proof Equipment Quality Supervision and Inspection Center
5. National Coal Mine Explosion-Proof Safety Product Quality Supervision and Inspection Center
6. Jiamusi Explosion-Proof Institute
7. Tianjin PCEC
8. Shanghai NEPSI
9. Beijing Coal Research Institute CCRI, etc.
For applicants, the type of explosion-proof and the level of explosion-proof required are essentially the same across all recognized institutions. They are all authorized by the state after recognition, possessing testing conditions that meet standard requirements, adhering to the same standards, and conducting the same testing. Under identical conditions, the trend towards choosing institutions offering more cost-effective services with more competitive prices is inevitable. This is also a significant reason why new explosion-proof enterprises are increasingly popular.
