Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. We have an extensive portfolio of consulting cases in the field of explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide clients with consulting services such as application assistance and factory audit guidance.
Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, domestic explosion-proof certifications are categorized into Explosion-proof 3C Certification and Explosion-proof Certificate Certification.
The explosion-proof certificate and explosion-proof 3C certification are for different types of explosion-proof products and fall under different certification models.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification.
Products listed in the catalog undergo explosion-proof 3C certification, following the "Product Testing + Factory Audit" model.
Both product type testing and factory on-site evaluation are required.
Ex-proof certification is applicable to products outside the Ex-proof 3C catalog. The certification model is Product Testing, and upon successful Product Testing, an Ex-proof certification can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certifications alone, but there is a risk of being penalized by market supervision. This is something for the client to consider on their own. When consulting, the client should first confirm the type of product and then decide on the certification model.
If you're unsure whether the product is listed in the explosion-proof 3C catalog.

Can ODM/OEM companies apply for explosion-proof certificates and explosion-proof 3C certifications? What are the requirements?
Many customers are asking whether their products are OEM manufactured, ODM branded, or purchased.
Can we apply for an explosion-proof certification or explosion-proof 3C certification?
Here, ZN Testing introduces the requirements and conditions for applying for explosion-proof certification and explosion-proof 3C certification.
If applying for an explosion-proof certification, the company only needs to provide the product's design drawings and samples.
No requirements regarding the presence of a production factory. Therefore, whether it's OEM, ODM, or products purchased directly, only
Provide the required drawings and samples for certification, and they can all apply for the explosion-proof qualification certificate.
Of course, the provided drawings and samples must comply with the requirements of the explosion-proof certification standards.
Applying for the explosion-proof 3C certification requires an additional factory audit and an annual supervision and evaluation, compared to the explosion-proof compliance certificate.
Therefore, the applicant must have their own production factory/OEM/ODM factory.
The application process is also more complex and costly, 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 the design and modification guidance for explosion-proof products.
Offer one-stop explosion-proof certification and explosion-proof 3C certification services, including design modification, drawing assessment, application, and factory audit for explosion-proof products.
