Requirements for防爆CCC certification application:
1. Product drawings and documentation: When a company applies for a防爆 certification for intrinsic safety electrical equipment, they should provide assembly drawings, circuit diagrams, printed circuit board drawings, silk-screened drawings, component material lists, and label drawings, 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 overall drawing can clearly indicate the product's explosion-proof parameters and structure, only the overall drawing needs to be submitted for testing.
2. Technical Documents: Include corporate standards/technical requirements. The corporate standards/technical requirements for the products should be written in the prescribed format, and their content should not only include performance requirements of the products but also cover related aspects of explosion-proofness: 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-proofness.
3. Additional Information: For products with adhesive bonding or casting, please provide the model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For products with plastic casings, please provide the material of the plastic and corresponding performance documents. Products with batteries require the provision of relevant battery specifications.

Composite explosion-proof products with a certificate of conformity for explosion-proof have components that fall under the CCC catalog, but the product itself is not listed in the explosion-proof CCC directory. How should this be handled?
ZhongNuo Inspection: If components are self-manufactured, a CCC certificate must be applied for. If purchased externally, components with a CCC certificate are required.

What are the requirements for obtaining the Coal Safety Certification and Mine Safety Certification?
Coal Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal Safety Certification is for equipment used in coal mines, while Mine Safety Certification is for non-coal mine equipment.
Certificates are all applied for, reviewed, and issued at the Anbang Standardization Center. Validity is 5 years, with annual supervision and review required.
Applying for both Coal Safety Certification and Mine Safety Certification requires passing two stages: product testing and factory inspection.
The applicant must possess design and development capabilities, and provide complete product design drawings.
And require an in-house production factory. Some products can also apply for Coal Mine Safety and Mine Safety certifications through the OEM process.
If distributors or end-users do not meet these requirements, they are unable to apply for the Coal Safety and Mine Safety Certification.
