How to obtain certification for explosion-proof electrical products not listed in the CCC certification catalog for explosion-proof products?
ZhongNuo Inspection: Currently, the product catalog only includes most explosion-proof electrical equipment. However, some explosion-proof equipment, such as large-scale system equipment and explosion-proof lighting, are not listed. These items still need to apply for an explosion-proof certification and obtain the certificate before they can be used in explosive hazardous areas.

What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market, and all equipment and products entering the EU market must pass the relevant CE directive certification.
For instance, there are EMC directives, LVD directives, MD directives, ATEX directives, and so on.
Different products are subject to different certification directives; the ATEX directive is specifically for explosion-proof equipment and products.
ATEX certification can be considered as the CE certification for explosion-proof products.
Each directive has different applicable standards; for the ATEX directive, the applicable standard is the EN60079 series.
Different explosion-proof types are applicable to different standard series.
For example, EN 60079.1 is the standard for explosion-proof, EN 60079.7 is the standard for increased safety, EN 60079.11 is the standard for intrinsic safety, and so on.

Requirements for materials to apply for the explosion-proof CCC certification:
1. Product Documentation: When applying for a防爆 certification for intrinsically safe electrical equipment, the applicant should provide assembly drawings, circuit diagrams, printed circuit board layouts, silk-screening diagrams, material lists for components, and label drawings, among others. 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 products should be written in the specified format, and their content should not only include performance requirements of the product but also cover防爆-related aspects: 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 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 battery specification sheet.

Products with composite explosion-proof types, which have obtained the explosion-proof certification, are not included in the explosion-proof CCC catalog, but the components within them are. 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.
