Can OEM models apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
This year, the Anbang Standards Center has gradually expanded the scope of applicants, including OEM production mode enterprises in the Anbang application range. This means that enterprises 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.
For your convenience in declaring, please familiarize yourself with the following requirements prior to product application:
Please first select the production location for the declared product. If the production location database does not contain the production location for the declared product, the applicant should choose "Add New Production Location" and then complete the production location information as required.
2. When the declared product is self-produced, the scope of business in the applicant's legal person business license should include the declared product; when the applied product is in an OEM production model, the OEM production factory should be a legal entity, and the scope of business in its legal person business license 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 pay attention to the validity period of the OEM agency 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.

Coal Safety/ Mine Safety Certification Differences
1. Distinctions in Definitions. Coal Mine Safety Certification, abbreviated as MA Certification, is self-explanatory, intended for use in underground coal mines. Mine Safety Certification, or KA Certification, refers to other metal or non-metal mines that are not coal mines, marking the fundamental difference.
2. The testing is different. During the type testing phase, their testing methods are also distinct. In terms of performance, both coal safety-certified products and mine safety-certified products undergo testing based on the same industry standards. However, when it comes to safety performance, coal safety certification requires explosion-proof testing according to the explosion-proof standard GB/T 3836, while mine safety certification equipment must be tested based on relevant industry standards. Coal safety certification is more inclined to prevent explosions, while mine safety certification focuses more on the safety performance of the product. This is the difference in their type testing.

Coal Mine Safety and Coal Mine Safety Certification Declaration Principles -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
1. Concurrent declaration of similar products
2. Multiple products share the same coal safety components
3. Electrical equipment pre-notification for complete machine declaration
4. Product molding followed by declaration

What explosion-proof certifications are required for explosion-proof products? What are the institutions for explosion-proof certification applications?
Currently, the certification models for explosion-proof products entering the Chinese market mainly include three types.
1. Issue explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines, which only require product testing; upon passing, the certificate is issued.
2. Conduct explosion-proof 3C certification; for products listed in the explosion-proof 3C catalog, product testing and factory inspections are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, featuring product testing and factory audit certification.
ZhongNuo Inspection is an institution offering explosion-proof certification application and consultation services.
