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 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 include the Explosion-Proof 3C Certification and the Explosion-Proof Compliance Certificate.
The explosion-proof certificate and explosion-proof 3C certification are for different types of explosion-proof products and fall under different certification models.
Starting 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, adopting the "Product Testing + Factory Audit" model.
Both product type tests and factory on-site assessments are required.
Ex-proof certificate is applicable to products not listed in the Ex-proof 3C Catalogue. The certification model is Product Testing; upon successful completion of Product Testing, an Ex-proof certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certification alone, but there's a risk of being penalized by market supervision. This is something for the customer to consider on their own. When consulting, the customer 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 Infrasafe 3C Catalogue.

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof compliance certificate?
Since the issuance in July 2019 regarding market supervision over explosion-proof electrical products and similar items
Following the announcement of the transition from production license to mandatory product certification management implementation requirements,
Many companies producing explosion-proof electrical products have gained a certain understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof certificate?
Does the product need an explosion-proof certificate to enter the market?
What are the additional requirements for a company to produce explosion-proof electrical products?
Actually, a careful reading of this announcement reveals that...
The announcement only includes a portion of explosion-proof electrical products in the scope of mandatory product certification.
(For details, refer to the product catalog of the mandatory explosion-proof electrical product certification.)
A significant portion of explosion-proof products remain unincorporated in the market.
For example, common pressure transmitters, flammable gas detectors, breathing valves, dust removal equipment, and mechanical products, etc.
Extraneous to the product catalog, explosion-proof equipment installed and used in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards.
Obtain the corresponding explosion-proof certification.

In July 2019, the market released an implementation announcement regarding the transition from production licenses to mandatory product certification for explosion-proof electrical products, etc.
The announcement clearly states that as of October 1, 2019, explosion-proof electrical equipment, household gas appliances, and household refrigerators with a rated volume of 500L or more will be included in the CCC certification management scope. Additionally, a transition period of 1 year is provided.
As of October 1, 2020, the above products have not obtained the mandatory product certification and are not marked with the mandatory certification logo.
Not for sale, distribution, import, or use in any business activities.
This means that in the future, enterprises applying for explosion-proof certification will become mandatory for the CCC certification, and will be implemented in accordance with the rules of the mandatory CCC certification.

Does a product need to have an explosion-proof design before applying for the explosion-proof 3C certification?
That's a given.
The product undergoes explosion-proof 3C certification, which involves passing the relevant test projects of the explosion-proof standards and the process of applying for the explosion-proof 3C certificate.
To ensure the product passes the explosion-proof standard test items, it is definitely necessary to design the product according to the test requirements, which is to implement explosion-proof design.
For explosion-proof requirements, refer to GB/T3836.1 and GB/T3836.2.
The design must refer to GB/T3836.1 and GB/T3836.4 for intrinsic safety.
The design of positive pressure should refer to GB/T3836.1 and GB/T3836.5.
