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 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; simply conduct product testing, and a certificate is issued upon passing.
2. Conduct explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory audit are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, involving product testing and factory audit certification.

The normal application process typically takes 6-7 months to obtain coal safety/mining safety certification.
Specifically, it is based on the customer's product structure and the information provided by the customer.

Do I still need a Coal Safety Certificate if the product has a防爆 certification?
The explosion-proof certificate and the coal safety certificate are applicable to different locations.
Explosion-proof certificates generally refer to facilities used in places where explosive gases and dusts are present, excluding underground coal mines.
Coal Mine Safety Certificate refers to the safety certification mark for equipment and products used underground in coal mines.
So, whether to apply for an explosion-proof certificate or a coal safety certificate depends on where the product is used.
If used only in non-mining explosive gas and dust environments, a防爆 certification is sufficient.
If used in underground coal mines, a coal safety certificate is required; the two certificates are not mutually applicable.
