Do you need a factory audit to apply for the Coal Safety/Mineral Safety mark?
Needed. Unlike obtaining a explosion-proof certification, stricter regulations apply to the control of mining marks.
Application for Coal Safety and Mine Safety Certification requires a factory audit of the applicant company.
Manufacturing facilities can be production-oriented, assembly-based, or OEM companies.

Coal Safety Certification is the abbreviation for Coal Mine Safety Certification.
In 2007, the Economic and Trade Commission and the Coal Mine Safety Supervision Bureau issued documents such as the "Temporary Measures for the Safety Marking of Coal Mine Products," implementing a safety production certification system for equipment, instruments, and meters used in underground coal mines, effectively preventing substandard products from entering the mines. The safety production marking system is a proven method.
To enhance coal mine safety, there is an increasing emphasis on the development of safety technology. The funding approach for technological development has been reformed. Due to insufficient safety investment, a financial guarantee mechanism for the research and development of safe production should be established.
Therefore, all types of equipment and products used in coal mine underground must pass the safety certification system of the Safety Standardization Center and obtain the corresponding coal safety certification.

How long does it take to apply for the Coal Safety/Mine Safety certification?
Due to the relatively complex process of applying for coal safety/mining safety certification,
Apart from the Testing time being controlled by our lab,
All others are processed through online applications and reviews, with timelines generally adhering to the review periods of the respective institutions.
Under normal application procedures, the certification period for Coal Safety/Mineral Safety usually takes 6-7 months.
Specifically, based on the customer's product structure and the information provided by the customer.

Do I need a Coal Safety Certificate if the product already has an explosion-proof certification?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
Ex-proof certificate generally refers to facilities used for explosive gases and dusts, excluding underground coal mines.
Coal 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-coal mine explosive gas and dust environments, a防爆certificate is sufficient.
If coal mine operations are involved, a coal safety certificate is mandatory; the two certificates are not mutually recognized.
