Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for the 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 we can provide clients with consulting services such as application assistance and factory audit guidance.
Which institution can apply for the explosion-proof 3C certification and 3C factory audit?
Intrinsically Safe 3C Certification is designed for electrical products listed in the Intrinsic Safety 3C Catalog.
Adopt the "Type Testing + Factory Audit" approach; the factory can be its own, or an OEM or ODM factory.
This certification is divided into two sections.
Firstly, product Testing is conducted in accordance with the GB/T3836 standard, and a Type Testing Report is issued upon successful completion of the Testing.
Firstly, conducting factory audits, which we refer to as "factory inspections," involves on-site evaluations of production facilities.
There are numerous 3C certification bodies, but finding one that specializes in explosion-proof 3C certification can be challenging.

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof qualification certificate?
ZhongNuo Inspection: Since the release in July 2019 regarding market products such as explosion-proof electrical equipment
Following the announcement of the transition from production license to mandatory product certification management implementation requirements,
Many companies producing explosion-proof electrical products have 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 qualification certificate?
Actually, just by carefully reading this announcement, you can understand that,
The announcement only includes a portion of explosion-proof electrical products within the scope of mandatory product certification.
(For detailed information, please 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, pressure sensors, dust removal equipment, and mechanical products.
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.
