What is Russian explosion-proof EAC certification
Russian explosion-proof certification (implementation regulation TR CU 012/2011, the mark is EAC-EX) is one of the mandatory documents, which gives the right to work with certain types of industrial equipment and equipment, and its name is usually added with the explosion-proof letters Ex.
In the fields of petroleum, chemical industry, energy, etc., for products and equipment operating in flammable and explosive environments, and products themselves have flammable and explosive properties, such products will need to do Russian explosion-proof certification when entering the Russian market for sale.
Which products need Russian explosion-proof EAC certification?
Specific classification of explosion-proof products:
Explosion-proof control box type, explosion-proof starter type, explosion-proof control switch type, explosion-proof main command electrical appliance type, explosion-proof junction box type,
Explosion-proof lamps type, explosion-proof connection type, explosion-proof fan type, explosion-proof electrical appliance with heating function type, explosion-proof alarm electrical appliance type, explosion-proof electromagnet type, explosion-proof other types, civil explosion-proof products.
What is an explosion-proof environment?
An environment where explosions may occur. (such as: flammable gas, dust environment, oil refinery, petrochemical plant, gas station, gas station, etc.), explosive gas environment Under atmospheric conditions, a mixture of gas, steam or mist-like flammable substances and air, after ignition in the mixture, the combustion will spread throughout the environment of the unburned mixture
Definition of explosion-proof equipment: electrical equipment that will not cause the surrounding explosive environment to ignite under specified conditions.
Classification of Russian explosion-proof equipment
Class I: Electrical equipment underground in coal mines;
Class II: Electrical equipment for all other explosive gas environments except coal mines and underground.
Class II can be divided into Class IIA, Class IIB, and Class IIC. Equipment marked with Class IIB can be applied to the use conditions of Class IIA equipment; Class IIC can be applied to the use conditions of Class IIA and Class IIB.
Class III: Electrical equipment in explosive dust environments other than coal mines.
Class IIIA: Combustible flying catkins; Class IIIB: Non-conductive dust; Class IIIC: Conductive dust.
Maximum surface temperature: The maximum temperature reached by any part of the electrical equipment that may cause ignition of the surrounding explosive environment when the electrical equipment is operating under the most unfavorable operating conditions within the specified range. The maximum surface temperature should be lower than the flammable temperature. Electrical equipment for explosive environments is divided into groups T1-T6 according to its maximum surface temperature.
