ATEX certification is the explosion-proof directive of the EU CE certification. The old directive was (94/9/EC), and the new ATEX directive 2014/34/EU.

The ATEX certification is applicable to a wide range of equipment, including fixed offshore platforms, petrochemical plants, flour mills, and other potentially explosive environments.

The ATEX explosion-proof certification directive has the following certification modes:  

(1) Mode A: Internal production control.

(2) B mode: EC type inspection. Document review product testing

(3) C mode: The type conforms. One way of quality assurance is through annual sample inspections

(4) D mode: Explosion proof system certification. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34

(5) E-mode: Product Quality Assurance System. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34

(6) F mode: Product validation. A way of quality assurance, verifying each batch of goods before export

(7) G-mode: Unit authentication. Single batch certification for a specific product

There are two certification modes for Class 1 products, B D and B F. B is type testing, D is explosion-proof system, and F is product verification. Choosing F, the certification body needs to come to the factory to inspect every product. Long term export incurs high costs, so choosing an explosion-proof system is more reasonable.

For the mode selection of Class 2 products, if the exported product is one (possibly multiple models), it is recommended to choose B C, and if multiple products are exported, it is recommended to choose B E.
