Is explosion-proof product certification the same as CCC certification? — Answer from Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
We generally refer to explosion-proof product certification as the safety certification required for explosion-proof products to enter the market, commonly known as explosion-proof certification, and the certificate issued is called an explosion-proof compliance certificate.
CCC Certification, which stands for "China Compulsory Certification," is abbreviated as CCC.
The CCC certification mark is denoted as "CCC," which is a product certification system established by the Certification and Supervision Commission in accordance with the "Regulations for Compulsory Product Certification" (Order No. 5 of the China Quality Supervision and Inspection and Quarantine Commission).
As of October 1, 2019, explosion-proof electrical equipment was officially included in the scope of mandatory product certification under market supervision.
Means that certain explosion-proof electrical equipment must be compulsorily applied for a 3C certification to enter the market and be circulated.
Some explosion-proof products are included in the CCC certification scope.
But explosion-proof product certification is not equivalent to CCC certification.
Only products within the Explosion-proof CCC Certification Catalog need to apply for CCC certification; explosion-proof products outside the catalog only require an explosion-proof qualification certificate.

What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion prevention for electrical equipment.
The housing is designed to withstand explosive mixtures entering through the housing joint surfaces or structural gaps, and to withstand internal explosions without damage.
And causes ignition of an explosive gas atmosphere formed by one or more gases or vapors.
The explosion-proof housing must possess both explosion-proof and anti-explosion capabilities. Generally, the outer casings of products designed for explosion-proof purposes are rather bulky.
Products and equipment suitable for fixed installation and use.
Combustion-proof interface width, gap, and roughness are the three key elements of explosion-proof housing design.
Design requirements for explosion-proof triad elements vary according to different explosive gas environments in Class I mining, non-mining Class IIA, IIB, and IIC.
Refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.
ZhongNuo Inspection has long been dedicated to explosion-proof product design, testing, and certification services.
We have a dedicated team in the explosion-proof field, well-versed in explosion-proof standards and requirements.
We offer explosion-proof housing design, drafting, modification guidance, and certification agency services.

Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, in China, explosion-proof certifications are divided into Explosion-proof 3C Certification and Explosion-proof Certificate Certification.
The explosion-proof certificate and explosion-proof 3C certification are for different types of explosion-proof products, each belonging to a separate certification model.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification.
Products listed in the catalog undergo explosion-proof 3C certification, adopting a "Product Testing + Factory Audit" model.
Both product type testing and factory on-site assessment are required.
Certificate of explosion-proof qualification is for products not listed in the explosion-proof 3C catalog. The certification mode is product testing; upon passing the product testing, the explosion-proof qualification certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for just the explosion-proof certification, but there's a risk of being penalized by market supervision. This is something the client needs to consider on their own. When inquiring, the client should first confirm the type of product and then decide on the certification model.
If you're unsure whether the product is listed in the explosion-proof 3C catalog.

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.
That 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, 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.
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.
