Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. We have an extensive portfolio of consulting cases in the field of explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide services such as application assistance and factory audit guidance.
Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, in China, explosion-proof certifications are categorized into Explosion-proof 3C Certification and Explosion-proof Compliance Certificate Certification.
The explosion-proof certificate and the explosion-proof 3C certification are for different types of explosion-proof products, belonging to separate certification models.
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 the "Product Testing + Factory Audit" model.
Both product type tests and factory on-site evaluations are required.
Certificate of Compliance for Explosion-Proof Products outside the Explosion-Proof 3C Catalog. The certification model is Product Testing; upon successful completion of Product Testing, the Certificate of Compliance for Explosion-Proof Products is issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certification alone, but there is a risk of being penalized by market regulation. This is something for the client to consider on their own. When consulting, the client should first confirm the type of product and then decide on the certification model.
If you're unsure whether the product is included 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.
As per 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 is a shorthand for Mine Safety Certification, which is a mandatory certification taken 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.

Requirements for applying防爆CCC certification:
1. Product Drawings and Documents: When an enterprise applies for a explosion-proof certification for intrinsically safe electrical equipment, it should provide assembly drawings, circuit diagrams, printed circuit board diagrams, silk-screening diagrams, material lists of components, and label diagrams, etc. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the explosion-proof performance of the sample (including assembly drawings and component drawings). If the assembly drawing can clearly indicate the explosion-proof parameters and structure of the product, only the assembly drawing needs to be submitted for inspection.
2. Technical Documentation: Includes corporate standards/technical requirements. The corporate standards/technical requirements for products should be written in the prescribed format, and their content should not only include performance requirements of the product but also relevant aspects of explosion-proof: such as basic parameters, explosion-proof markings, operating environmental conditions, explosion-proof performance requirements, relevant tests for explosion-proof performance, and markings related to explosion-proof.
3. Additional Information: For products with adhesive bonding or casting, provide the型号 and name of the adhesive and casting agent, along with performance descriptions and relevant process documents. For plastic shell products, supply the material and corresponding performance documents. Battery-equipped products require a battery specification sheet as well.
