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 we can provide services such as application assistance and factory audit guidance.
Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, domestic explosion-proof certifications are categorized into Explosion-proof 3C Certification and Explosion-proof Certificate of Conformity.
The explosion-proof certificate and the 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 require explosion-proof 3C certification, following the "Product Testing + Factory Audit" model.
Both product type testing and factory on-site evaluation are required.
Ex-proof certification is applicable to products not listed in the Ex-proof 3C Catalog. The certification model is Product Testing; once the Product Testing passes, an Ex-proof certification can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certifications, but there's a risk of being penalized by market supervision. This is something for the client to consider on their own. When consulting, the client should first confirm what type of product it is, 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.
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 method.
Coal Mine 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.

Explosion-proof electrical 3C certified products include:
Explosion-proof motor
Explosion-proof electric pump
Explosion-proof electrical distribution equipment products
Explosion-proof switches, control and protection products.
Explosion-proof starters
Explosion-proof transformers and related products
Explosion-proof electric actuators, solenoid valve products.
Explosion-proof connector assembly
Explosion-proof surveillance products
Explosion-proof communication and signaling equipment
Explosion-proof air conditioners, ventilation equipment.
Explosion-proof electric heating products
Explosion-proof accessories, Ex components.
Explosion-proof instruments and meters
Explosion-proof sensor
Safety barrier products
Explosion-proof instrument cabinets and related products.
Explosion-proof lighting and control devices.

Requirements for application materials for the explosion-proof CCC certification:
1. Product Technical Drawings: When an enterprise applies for a防爆 certification for intrinsically safe electrical equipment, it should provide assembly drawings, circuit diagrams, printed circuit board layouts, silk-screened diagrams, component material lists, and label drawings, etc. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the sample's explosion-proof performance (including assembly drawings and component drawings). If the assembly drawing clearly indicates the product's explosion-proof parameters and structure, only the assembly drawing needs to be submitted for inspection.
2. Technical Documentation: Includes corporate standards/technical requirements. The corporate standards/technical requirements for the product should be written in the specified format. The content should, in addition to the performance requirements of the product, also include relevant aspects of explosion-proof: such as basic parameters, explosion-proof markings, usage 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 model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For plastic shell products, supply the material type and corresponding performance documents. Battery-equipped products require the provision of battery specifications.
