Can the foreign explosion-proof certification be converted to the Chinese CCC explosion-proof certification? What documents are required?
ZhongNuo Testing: No, the foreign explosion-proof certification Testing unit is not our CCC laboratory, therefore the issued Report is not recognized.
In the future, all imported products listed in the CCC Catalog must undergo CCC certification in China.

What explosion-proof certifications are required for explosion-proof products? What institutions are available for explosion-proof certification applications?
Currently, the certification models for explosion-proof products entering the Chinese market mainly consist of three types.
1. Provide explosion-proof certification for equipment used in environments with explosive gases and combustible dust in non-coal mines.
Simply conduct product testing; a certificate will be issued upon passing the test.
2. Conduct 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, involving product testing and factory audit certification.
ZheNuo Inspection is an institution that offers consulting services for explosion-proof certification applications.
We offer a one-stop service for explosion-proof certification and coal safety certification, including product design and modification, drawing evaluation, application, and factory audit.
Proficient in certification standards and processes, with extensive case studies and experience. Feel free to DM us for more details!

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof compliance certificate?
ZhongNuo Inspection: Since the release in July 2019 regarding market issues and explosion-proof electrical products, etc.
Following the announcement of implementation requirements for mandatory product certification management after the transition from production permit to mandatory product certification,
Many companies producing explosion-proof electrical products have gained some 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?
In fact, a close reading of this announcement reveals,
The announcement only includes certain explosion-proof electrical products within the scope of mandatory product certification.
(For details, see the product catalog of the mandatory explosion-proof electrical product certification.)
A significant portion of explosion-proof products have not yet been included in the market.
For example, common pressure transmitters, combustible gas detectors, breath valves, pressure sensors, dust removal equipment, and mechanical products, etc.
Explosion-proof equipment installed and used in explosive areas, outside of the product catalog, must strictly adhere to the requirements of the GB/T3836 series explosion-proof standards.
Obtain the corresponding explosion-proof certification.
