Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
Currently, the frequent occurrence of coal safety certification is at the Safety Standard Center. Below the Safety Standard Center, there are various local Testing Institutions.
Responsible for product testing tasks in different product fields.
Generally, when a company applies for a coal safety certification, they cannot directly find a lab to conduct the testing.
Only by the Testing Certification issued by the Anbang Center to Anbang Labs.
Actually, the domestic coal safety certification system is quite strict. It combines type testing with factory production system review.
To ensure the applicant company is capable of ensuring product production and capacity.
Even after obtaining the coal safety certification, the company must still undergo an annual supervision and evaluation by the Safety Standardization Center.

What are the requirements for applying for coal safety certification and mine safety certification?
Coal Mine Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal safety certification pertains to equipment used in coal mines, while mine safety certification applies to non-coal mine equipment, both are applied for, reviewed, and certified by the Safety Standard Center.
Certificates are valid for 5 years and require annual supervision and review.
Applying for Coal Safety and Mine Safety certifications requires passing two stages: product testing and factory inspection. Applicants must possess design and R&D capabilities, provide complete product design drawings, and have their own manufacturing facility.
Some products can also apply for Coal Safety Certification and Mine Safety Certification through OEM.
If dealers or users do not meet these qualifications, they are unable to apply for the Coal Safety and Mine Safety certification.
Shenzhen ZhongNuo Inspection, as a coal safety and mine safety certification body, is well-versed in the standards and requirements. We have a team of experienced engineers and factory audit services, capable of providing services from online application, product design and modification, drawing and documentation revision, to factory audits, helping businesses smoothly obtain coal safety and mine safety certifications.

What test items are required to apply for an explosion-proof certification?
Explosive-proof products must pass relevant tests according to the explosive-proof standards to obtain an explosive-proof certification.
Different explosion-proof types, catering to equipment used in various explosive environments, entail different explosion-proof testing projects.
Many clients also want to know which test items are required for explosion-proof products? What specific requirements are there for the explosion-proof design of the product?
Next, let's provide examples of common explosion-proof testing items.
For example, in intrinsically safe products, typical testing items include appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, and more.
Flameproof products mainly undergo tests including heat and cold resistance tests, internal ignition without propagation of explosion, shell pressure resistance, IP testing, temperature rise tests, etc.
Various test items, tailored to different modules or components of the product, each test ensures the product meets the explosion-proof standards and achieves the required explosion-proof performance.
If a company is designing explosion-proof products and is unaware of the explosion-proof standards requirements,
ZhongNuo Inspection offers guidance services for explosion-proof circuit and structure design, including explosion-proof standards, design key points, drawing guidance, and can also act as an agent for explosion-proof testing and certification services.

Do I need a Coal Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
The explosion-proof certificate generally refers to locations where explosive gases and dusts are present, excluding underground coal mines.
Coal Mine Safety Certificate refers to the safety certification mark for equipment and products used underground in 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certification is sufficient.
If coal mine operations are involved, a coal safety certificate is absolutely necessary; the two are mutually non-transferable.
