Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
In explosive environments, explosion-proof electrical equipment must be used, with a valid explosion-proof certificate; electrical equipment intended for use in coal mines must obtain a coal safety certification prior to being brought down into the mine—this is a requirement of our relevant regulations. Beyond the coal industry, the petrochemical, metallurgical, and other industrial sectors must also use explosion-proof electrical equipment to ensure production safety and prevent explosion accidents.
The current safety production situation in our country remains extremely serious, with explosion accidents occurring frequently. It is urgent to strengthen safety production efforts across all industrial sectors. For coal mining enterprises, selecting reliable explosion-proof equipment is one effective means to effectively curb explosion accidents.

Can the OEM model apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
This year, the Anbang Standard Center has gradually expanded the scope of applicants, including OEM production mode companies in the Anbang application range. This means that companies previously operating under the OEM production model can now apply for the Coal Safety Certification themselves. However, there is no actual implementation as of now. The potential issues that may arise during actual implementation remain unknown.
Please familiarize yourself with the following requirements prior to applying for the product for your convenience in declaration.
Please first select the production address for the declared product. If the production address database does not contain the production address for the declared product, the applicant should choose "Add New Production Address" and then complete the production address information as required.
2. If the declared product is self-manufactured, the scope of business in the applicant's corporate business license should include the declared product. If the applied product is produced under the OEM production model, the OEM production factory should be a legal entity, and its corporate business license scope of business must include the declared product.
3. When the production address is leased, the applicant should pay attention to the validity period of the lease agreement. If the declaration time is less than five years from the termination date of the lease agreement, the validity period of the safety mark will be affected by the validity period of the lease agreement.
4. For products manufactured under the OEM model, applicants should note the validity period of the OEM entrustment agreement. If the declaration time is less than five years from the termination date of the OEM contract, the validity period of the safety mark will be affected by the contract's validity.

Have a coal safety certification; how to apply for another mine safety certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
If the product has already undergone the Coal Safety Certification, a new Mine Safety Certification can be applied for using the original Certificate and Report. This requires a new application process, but it will significantly reduce the time and cost. So, how to apply for the Coal Safety Certification if there's already a Mine Safety Certification? If the product has already been certified for Mine Safety and needs to apply for the Coal Safety Certification again, it must be applied for as a new product.

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. Issue explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines, requiring only product testing; upon passing, certificates are 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.
