TR CU 012/2011 Hazardous Atmospheres
Also known as ATEX CERTIFICATE
The TR CU 012/2011 EAC was created for electrical devices, their components and to equipment not running on electrical power that operate in fire-hazardous environment (for example, mine shaft).
The certified products carry distinct EX mark indicating ignition/explosive equipment. The EX mark is also known as “Certificate EAC EX” which refers to the explosion safety features of the product.
European Union equivalent of this certificate is ATEX, but, unlike ATEX directive, the EAC TR CU 012/2011 does not apply to devices for medical use.
