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 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; 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 explosion-proof, EN 60079.7 is the standard for increased safety, EN 60079.11 is the standard for intrinsic safety, and so on.
