EX EAC certificate for hazardous atmospheres TR CU 012/2011, Atex for Russia
The EX EAC certificate and the regulation for equipment used in potentially explosive atmosphere, therefore classified explosion proof, is based on the Technical Regulations 012/2011 of the Eurasian Customs Union (TR CU 012/2011), one of the EAC Technical Regulations in force since 2012.
The Custom Union Technical Regulations regulate the quality of the product on the markets of Russia, Belarus, Kazakhstan and soon of Armenia and Kyrgyzstan. The certificate resulting from the compliance with the provisions of the TR CU 012/2011 is the EX EAC certificate, comparable to European ATEX.
The regulation sets the safety standards for devices and equipment used running in potentially explosive atmospheres.
Explosion protection certification EAC confirms that explosion-proof equipment has been tested and meets specific safety standards to prevent ignition in hazardous atmospheres. This certification, often referred to as an explosion-proof equipment certificate of conformity, signifies compliance. The magazine “Ex-equipment,” first published in 2005, provides information on the history of explosion protection.
To understand explosion protection, it’s important to review the characteristics and specifications of relevant equipment. The history of mandatory certification requirements for materials in the Russian Federation provides context for understanding current explosion protection standards.
The foundation of modern explosion protection lies in recommendations from the International Electrotechnical Commission (IEC), adopted by numerous countries worldwide. These international standards have influenced regional requirements. For instance, in Russia, the GOST standards play a crucial role, while the USA follows FM standards, and Europe adheres to ATEX directives. Despite regional differences, these standards share common approaches and classification methods for explosion-proof equipment. Understanding the evolution of these standards is key to navigating the landscape of explosion safety.
In Russia, several GOST standards, including GOST 22782, GOST R 51330, 52350, and GOST R IEC 60079, define the classification and requirements for explosion-proof equipment. These standards cover various aspects, including equipment design, testing procedures, and safety markings. Proper classification of explosion-proof electrical equipment is essential for ensuring safety in potentially explosive environments. For example, product designation 51330.0-99 provides specific information about the type and characteristics of explosion-proof electrical equipment, distinguishing between different protection levels.
Explosion-proof equipment encompasses a wide range of devices designed for use in hazardous areas. These devices may include components for monitoring, controlling, and regulating processes, all engineered to prevent ignition sources in the presence of flammable substances. The history of ignition events has significantly shaped the development and refinement of explosion-proof technologies and standards. Telecommunication equipment intended for use in hazardous areas also falls under the scope of explosion protection requirements.
Obtaining an explosion protection certificate involves specific procedures. Manufacturers typically apply for certification, which, if granted, covers the production and supply of their products for a maximum period, often three years, subject to annual inspection controls. The application process can be initiated by the manufacturer, the supplier, or the buyer of the equipment. The certificate specifies the explosion protection level of the equipment, indicating the types of hazardous environments in which it is safe to operate. Understanding the different explosion protection levels is crucial for selecting the appropriate equipment for a given application.
EX EAC certificate: products subject to the legislation for the safety of appliances in explosive atmosphere
The TR CU 012/2011 EAC is addressed both to electrical devices and their components and to equipment not running on electrical power.
The identification of products meeting the specifications listed in the regulation is done through the presence hte Ex marking, placed on the product and on the product documentation. The EX mark result in the name “Certificate EAC EX” which for instance refers to the EAC certificate of the unified regulations of the Customs Union which Russia, Belarus and Kazakhstan are part with a joint certification system, whereas EX refers to the explosion safety features of the product.
In contrast with the ATEX directive, the EAC TR CU 012/2011 does not apply to devices for medical use.

It is important to note that the certification in accordance with the Technical Regulations 012/2011 EAC is to be achieved on both the sold devices and all the components giving the equipment the special properties. This procedure allow the device to be in potentially explosive atmospheres, and it is to be performed if the components have not been previously certified under the Regulation of the Custom Union.
The certification process depending on the type of product and the temporal validity of the certificate may vary. Furthermore different procedures may be required for single export certificate and longer terms up to a maximum of 5 years. Very often it requires an inspection at the manufacturing plant or specific tests on samples of the equipment, as well as extensive documentation in Russian language.
