Which institution can apply for the explosion-proof 3C certification and 3C factory audit?
Inherently safe 3C certification is applicable to electrical products listed in the Inherently Safe 3C Catalog.
Adopt the "Type Test + Factory Audit" approach, where 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 for explosion-proof testing. Upon successful testing, a type examination report is issued.
Firstly, conduct factory audits, which we refer to as "factory inspections," involving on-site assessments of production facilities.
There are numerous 3C certification agencies, but finding one capable of handling explosion-proof 3C certification is crucial.

What explosion-proof certifications are required for explosion-proof products? What are the institutions for applying for explosion-proof certifications?
Currently, the certification models for explosion-proof products entering the Chinese market are primarily three in number.
1. Obtain explosion-proof certificates 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. Conduct explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory audits 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 that offers consultation for explosion-proof certification applications.
We offer a one-stop service for explosion-proof certification and coal safety certification, including product design, modification, drawing evaluation, application, and factory audit.
