What is the difference between ATEX certification and CE certification?
CE certification is a mandatory certification in the EU market; 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 require different certification directives, with the ATEX directive specifically for explosion-proof equipment and products.
ATEX certification can be likened to the CE certification for explosion-proof products.
Each directive has different applicable standards; the ATEX directive's 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 flameproof, EN 60079.7 is the standard for increased safety, and EN 60079.11 is the standard for intrinsic safety, etc.

Do imported explosion-proof electrical equipment need to apply for the CCC certification?
The CCC certification is a mandatory product certification in China, meaning that all explosion-proof electrical equipment listed in the CCC product catalog must obtain a CCC certification certificate.
Imported products that fall under the CCC product catalog and are for sale.
Also, obtaining the CCC certification is required. The process for applying for the explosion-proof CCC certification for imported explosion-proof electrical equipment is essentially the same as the process for domestic production products.
All must undergo application, type testing, and factory audit. If the factory is overseas, a factory audit must also be conducted abroad.
