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.
What explosion-proof certifications are required for explosion-proof products? Which organizations handle the application for explosion-proof certifications?
Currently, the certification models for explosion-proof products entering the market in China mainly consist of three types.
1. Obtain explosion-proof certification for equipment used in environments with explosive gases and combustible dust in non-coal mines.
Just need product testing, and a certificate will be issued upon passing.
2. Obtain explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory inspections are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, featuring product testing and factory audit certification methods.
ZhongNuo Inspection is an institution offering explosion-proof certification application consultation.
We offer a one-stop service for explosion-proof certification and coal safety certification, including product design modification, drawing evaluation, application, and factory audit.
Proficient in certification standards and processes, with a wealth of case studies and experience. Feel free to message us!

After the explosion-proof CCC certification has replaced the production license, is an explosion-proof compliance certificate still required?
ZhongNuo Inspection: Since the release in July 2019 regarding explosion-proof electrical products and the like in the market
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, a careful reading of this announcement will reveal,
The notice only includes a portion of explosion-proof electrical products in the scope of mandatory product certification.
(For details, see the product catalog of the mandatory explosion-proof electrical product certification.)
There are still a large portion of explosion-proof products not included in the market.
For example, common pressure transmitters, combustible gas detectors, breathing valves, pressure sensors, 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.

Which institution can apply for the explosion-proof 3C certification and 3C factory audit?
Intrinsically safe 3C certification is for the explosive electrical products listed in the Intrinsically Safe 3C Catalog.
Adopt the "Type Test + 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 the production facilities.
There are numerous 3C certification bodies, but finding one capable of handling explosion-proof 3C certifications is crucial.
