Do you have a product catalog for explosion-proof electrical equipment that has been converted to mandatory product certification (CCC certification)?
ZhongNuo Inspection: Yes. The market has transitioned from production permits to mandatory product certification for explosion-proof electrical equipment at the same time as its release.
Also issued a notice on the transition of explosion-proof electrical products from production license to mandatory certification scope.
Products listed in the product catalog must be manufactured, sold, or engaged in other business activities during the transitional period with a valid production license or CCC certification.
After the transitional period, only products with valid CCC certification can be manufactured, sold, or otherwise engaged in business activities.

Requirements for防爆CCC certification application:
1. Product Documentation: When applying for a防爆 certification for intrinsic safety electrical equipment, the applicant should provide assembly drawings, circuit diagrams, printed circuit board layouts, silk-screening diagrams, material lists for components, and label diagrams, etc. For non-intrinsic safety electrical equipment, the technical documents submitted for testing 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 testing.
2. Technical Documentation: Includes corporate standards/technical requirements. The corporate standards/technical requirements for the products should be written in the prescribed format, with content that not only covers performance requirements of the product but also includes relevant aspects of explosion-proof: such as basic parameters, explosion-proof markings, environmental conditions of use, 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, please provide the型号 names, performance descriptions, and relevant process documents for the adhesives and casting agents. For plastic shell products, please supply the material type and corresponding performance documents. Products with batteries require a specification sheet for the batteries.
