Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
What 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 mainly consist of three types.
1. Obtain explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines. Simply conduct product testing; upon passing, the certificate is issued.
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 process.
ZhongNuo Inspection is an institution offering explosion-proof certification application and consultation services.
We offer a one-stop service for explosion-proof certification and coal mine safety certification, including防爆 design and modification, drawing evaluation, certification acquisition, and factory inspection.

Do I still need a Coal Mine Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and 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 in underground 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 certificate is sufficient.
If mining operations are involved, a coal safety certificate is mandatory; the two certificates are not interchangeable.
