Xiamen Low-Voltage Switchgear Mine Safety Certification Assistance: Enterprise Standard Writing

Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
Now that we have the explosion-proof 3C certification, how do we transition to the coal mine safety or mine safety certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
In China, explosion-proof 3C certification/examination certificate and coal safety/mining safety certification belong to different management systems, and the product usage sites are also different. The two certificates belong to different certification systems and are relatively opposing. Regardless of which certificate is held, the other certificate needs to be reapplied for according to the new product application process. Similarly, if a coal safety/mining safety certification is obtained, applying for an explosion-proof examination certificate or explosion-proof 3C certification also requires reapplication according to the new application process.

Coal Mine Safety Sign Certification is a mandatory certification implemented by the Coal Mine Safety Sign Office for items used underground in mines. Any product listed in the Coal Mine Product Safety Certification Catalog must obtain a certification certificate.
Products with coal safety/mining safety certification can affix the MA/KA mark. Individuals and entities are prohibited from selling, purchasing, or using mining products that are included in the safety mark management directory but have not obtained a safety mark.
The manufacturer of the product must go through several steps to obtain a safety mark, including filling out an application form, preliminary review and qualification registration, evaluation, and issuance of the certificate.

What's the difference between applying for ATEX certification and coal mine safety certification for products?
intrinsic safety certification, also known as intrinsic safety explosion-proof certification.
In the explosion-proof industry, there are various types of explosion-proof protection, including flameproof, intrinsic safety, increased safety, positive pressure, and sealed type, etc.
Intrinsically safe is just one type of explosion-proof design. Equipment using this type of explosion-proof design in explosive areas is inherently safe because its operating voltage, current, capacitance, inductance, etc., are restricted. Even if sparks are generated within the circuit, they are not sufficient to ignite the surrounding explosive environment.
The ATEX certification is widely used in low-power, low-energy instruments, handheld terminal products, and other equipment.
Coal Mine Safety Certification is a mandatory safety certification for equipment used underground in coal mines.
Due to the presence of explosive substances like methane in underground coal mines, electrical equipment used in such mines must be equipped with protective measures to achieve explosion-proof performance.
Select appropriate explosion-proof protection types, such as intrinsically safe, flameproof, and encapsulated, based on product structure, electrical parameters, installation method, and usage area.
It's worth noting that electrical equipment applying for the Coal Mine Safety Certification must not only possess explosion-proof capabilities but also meet performance tests for the special underground environment of coal mines.
ZhongNuo Inspection has long been dedicated to explosion-proof certification and coal safety certification, well-versed in certification standards and product explosion-proof design, rectification, testing, certification, and factory audit processes and requirements. We can assist companies in swiftly applying for explosion-proof and coal safety certifications.

Do I need a Coal Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and the coal safety certificate are applicable to different locations.
explosion-proof certificate generally refers to places used for various explosive gases and dusts, excluding coal mine shafts
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-mining explosive gas and dust areas, a防爆 certificate is sufficient.
If the coal mine underground is to be used, a coal safety certificate is absolutely necessary, and the two are mutually incompatible.
