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 example, there are EMC directives, LVD directives, MD directives, ATEX directives, etc.
Different products are subject to various certification directives; the ATEX directive, for instance, is specific to explosion-proof equipment and products.
ATEX certification can be considered as the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive applies to the EN60079 series.
Different explosion-proof types are applicable to various standard series.
For example, EN 60079.1 is the standard for flameproof, EN 60079.7 is the standard for increased safety, and EN 60079.11 is the standard for intrinsic safety, etc.

Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen Zhongnuo Inspection Technology Co., Ltd.
Based on the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been added 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 means of "type testing + factory audit."
Coal Safety Certification is the abbreviation for Coal Mine Safety Certification, which 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, and there is no mutual recognition between them.
The Coal Safety Certification and Explosion-proof 3C Certification are mutually independent.
The coal safety certification or the explosion-proof 3C certification cannot be substituted or converted for each other; they must be applied for separately.

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
Which certification is required for a company's explosion-proof products to enter the market? What are the requirements for the applicant company, etc.? These are many of the current confusions faced by businesses.
Below, ZN Testing demystifies it for you.
Firstly, both explosion-proof certificates and explosion-proof CCC certifications are certification requirements for explosion-proof equipment.
Whether to apply for an explosion-proof certificate or explosion-proof CCC certification mainly depends on the product category.
Put simply, it's about checking whether your product is listed in the Explosion-Proof CCC certification product catalog.
Yes, you need to obtain the explosion-proof CCC certification; no, just get the explosion-proof compliance certificate.

Requirements for applying for the explosion-proof CCC certification:
1. Product drawings and documents: When applying for a防爆ex-proof certificate for intrinsic safety electrical equipment, the applicant should provide assembly drawings, circuit diagrams, printed circuit board drawings, silk-screened drawings, material lists for components, and label drawings, among others. For non-intrinsic safety 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 overall drawing clearly indicates the product's explosion-proof parameters and structure, only the overall 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防爆 aspects: such as basic parameters, explosion-proof markings, environmental conditions for 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, 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. Products with batteries require the provision of battery specifications.
