Shenzhen ZhongNuo Inspection & Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
Basic Process and Agencies for Coal Safety Certification
Coal safety certification is a mandatory safety certification for equipment and products used in coal mine underground, which adopts the "Product Testing + Factory Audit" approach. This involves both testing the application products and conducting on-site audits and annual supervision reviews of the production factories for the products, which is commonly referred to as factory inspections.
The product testing aspect requires compliance with coal safety standards, such as electrical products needing to meet explosion-proof requirements in coal mine gas environments, as well as product performance standards.
Factory audits primarily focus on the assessment of the factory based on the ISO9001 production quality system, combined with the requirements of the Mine Product Safety Mark Implementation Rules. The Safety Mark Center is the coal safety certification issuing and inquiry institution.
Shenzhen Zhongnuo Inspection offers coal safety certification and consulting services, well-versed in the entire certification process and requirements. We have a team of explosion-proof technology engineers and factory audit specialists to assist companies in conveniently and quickly applying for coal safety certification. Our successful cases include light boxes, remote controls, fiber optic temperature measurement devices, sensors, air compressors, mobile phones, thermal imaging cameras, and patrol robots.

Can OEM models apply for the Coal Mine Safety Certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
This year, the Anbao Center has gradually expanded the scope of applicants, including OEM production mode enterprises in the Anbao application range. This means that enterprises previously adopting 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 legal person's business license should include the declared product. If the application is for OEM production, the OEM manufacturer should be a legal entity, and its business license scope must cover 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 date 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 OEM-manufactured products, applicants should pay attention to the validity period of the OEM commission 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 -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
1. Definition Differences. Coal Safety Certification, abbreviated as MA Certification, is self-explanatory as it's used in underground coal mines. Mine Safety Certification, or KA Certification, is for non-coal mines and other metal or non-metal mines; this is the fundamental distinction.
2. The testing is different. In the type testing phase, their testing methods also vary. 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, following the explosion-proof standard GB/T 3836. Mine safety certification, on the other hand, relies on industry standards for testing equipment safety performance. Coal safety certification is more inclined to prevent explosions, while mine safety certification prioritizes safety performance. This is the difference in their type testing.
