Which explosion-proof certifications are required for explosion-proof products? What institutions offer explosion-proof certification applications?
Currently, the certification models for explosion-proof products entering the Chinese market primarily consist of three types.
1. Obtain explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines.
Just need product testing, certificate issued upon passing.
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, featuring product testing and factory audit certification.
ZhongNuo Inspection is an institution offering explosion-proof certification application consulting.
We offer a one-stop consulting service for explosion-proof certification and coal safety certification, including product explosion-proof design and modifications, drawing evaluations, applications, and factory inspections.
Familiar with certification standards and processes, with rich cases and experience. Feel free to DM us!

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
Which certification is required for a company's explosion-proof products to enter the market? What are the requirements for the applying company, etc.? These are many of the current dilemmas faced by businesses.
Below, ZhongNuo Inspection explains in plain language for everyone's clarification.
Firstly, both explosion-proof certification and explosion-proof CCC certification are certification requirements for explosion-proof equipment.
Whether to obtain the explosion-proof certificate or the explosion-proof CCC certification largely depends on the product category.
Put simply, it's to see if your product is listed in the explosion-proof CCC certification product catalog.
Yes, you need to obtain the explosion-proof CCC certification; no, just get the explosion-proof compliance certificate.

Which institution can apply for the explosion-proof 3C certification and 3C factory audit?
Explosion-proof 3C certification is for explosion-proof electrical products listed in the explosion-proof 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 according to the GB/T3836 standard for explosion-proof testing. Upon successful testing, a type inspection report is issued.
Firstly, conducting factory audits, which we refer to as "factory inspections," involves on-site evaluations of the manufacturing facilities.
There are numerous 3C certification bodies, but finding one capable of handling explosion-proof 3C certification is crucial.
