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 market-related regulations on explosion-proof electrical products, etc.
Following the announcement of the transition from production license to mandatory product certification management implementation requirements,
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 announcement reveals that only a portion of explosion-proof electrical products have been 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, combustible gas detectors, breathing valves, intelligent scanning terminals, dust removal equipment, and mechanical products, etc.
Installation and use of explosion-proof equipment in explosive areas, outside of the product catalog, must strictly comply with the requirements of the GB/T3836 series explosion-proof standards and obtain the corresponding explosion-proof certification.

What products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
This is a type of explosion-proof protection, which limits electrical energy, ensuring that the equipment remains safe 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.
Simultaneously, there are clear requirements for the power supply method of intrinsically safe equipment, plastic enclosures, and wireless transmission.
To apply for the intrinsically safe certification of the product, the principle diagram and PCB diagram of the product must be provided.
Zhenuo Testing has dedicated engineers specializing in intrinsic safety 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 intrinsic safety levels ia, ib, and ic.

Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Testing Technology Co., Ltd.
Based on the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been transferred to the mandatory product certification catalog.
It 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 Safety Certification, commonly abbreviated 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, with 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 CCC certification?
The CCC certification is a mandatory product certification in China, which means that all explosion-proof electrical equipment listed in the CCC catalog must obtain a CCC certification certificate.
Imported products that are listed in the CCC catalog and are intended for sale.
Also, obtaining the CCC certification is required. The process for applying for the explosion-proof CCC certification for imported electrical equipment is essentially the same as the process for applying for the certification for domestically produced products.
All must undergo application, type testing, and factory audit. If the factory is overseas, an on-site audit must also be conducted abroad.
