After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof qualification certificate?
ZhongNuo Inspection: Since the release in July 2019 of the market regulations concerning explosion-proof electrical products, etc.
Following the announcement of the implementation requirements for mandatory product certification management after the transition from production license to mandatory product certification management,
Many companies producing explosion-proof electrical products have gained a certain understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof qualification certificate?
Actually, a close reading of this notice reveals that only a portion of explosion-proof electrical products are included in the scope of mandatory product certification (for details, refer to the product catalog for mandatory explosion-proof electrical product certification).
There are still a large number of explosion-proof products not included in the market, such as common pressure transmitters, flammable gas detectors, breathing valves, intelligent scanning terminals, dust removal equipment, and mechanical products, etc.
Extraneous explosion-proof equipment installed in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards and obtain the corresponding explosion-proof certification.

Which products can apply for the intrinsically safe explosion-proof certificate? What are the requirements?
Beneath-Arc is one type of explosion-proof protection, which restricts electrical energy so that the equipment will not ignite even in the event of a fault.
A type of explosion-proof protection that the energy produced is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsic safety requirements limit the current, voltage, capacitance, inductance, etc., of electrical equipment, making it only suitable for low-power devices.
Additionally, there are specific requirements for the power supply method of intrinsically safe equipment, plastic housing, and wireless transmission.
To apply for intrinsic safety certification, the product's schematic diagram, PCB layout, and other relevant documents must be provided.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We offer technical consulting services for explosion-proof circuit design, drafting, and modifications. We have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic explosion-proof classifications.

Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Inspection Technology Co., Ltd.
Pursuant to the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been transferred to the mandatory product certification catalog.
This is the CCC certification. Products under the explosion-proof 3C certification category obtain the explosion-proof CCC certification by undergoing a "type test + factory audit" certification process.
Coal Mine Safety Certification, commonly referred to as "煤安认证," is a mandatory certification implemented by the Safety Standardization Center for all types of products and equipment used underground in coal mines.
The certification method combines "type testing" with "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments, and there is no mutual recognition between them.
Coal safety certification and explosion-proof 3C certification are independent of each other.
The coal safety certification or the explosion-proof 3C certification cannot be substituted or converted for each other; they must be applied for separately.

Do imported explosion-proof electrical equipment need to apply for the CCC certification?
The CCC certification is a mandatory product certification in China, meaning that all explosion-proof electrical equipment listed in the CCC product catalog must obtain a CCC certification certificate.
Imported products that are listed in the CCC catalog and are for sale,
You must obtain the CCC certification certificate. The process for applying for a防爆CCC certification for imported explosion-proof electrical equipment is essentially the same as the process for domestically produced products.
All must undergo application, type testing, and factory audit. If the factory is overseas, an on-site factory audit must also be conducted abroad.
