TR CU 032: to which products does it apply?

TR CU 032/2013 is the legislation that regulates all aspects of the design, construction, and installation of pressure equipment within the Eurasian Customs Union, in association with national GOSTs and other directives issued by competent bodies. The purpose of the Technical Regulations is guaranteed for specific product categories within the Eurasian Customs Union, which includes Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan.

TR CU 032, specifically, applies to:

  • Containers for liquids and gases with pressure higher than 0.05 Mpa.
  • Flame boilers obtain to obtain water or steam, and the pressure of which is higher than 0.05 Mpa, including vessels with heating a.
  • Obtain pipes for gas, steam, and liquids with a maximum permissible operating pressure of over 0.05 Mpa and a nominal diameter of around 25mm.
  • Elements of the systems (single units) and components for them, designed to be applied on equipment and systems subjected to the impact of pressure.
  • Valves for fluids and gases with a nominal diameter greater than 25mm and maximum operating pressure greater than 0.05 Mpa.
    Hyperbaric chambers are not for medical use.
    Safety devices and pressure safety devices and devices.

The following types of products are exceptions, for which certification of conformity is not required:

  • main conduct;
  • gas distribution networks;
  • equipment for use in the field of nuclear energy;
  • equipment for use on the sea and inland waterways;
  • railway vehicle braking systems;
  • containers for use on airplanes;
  • military equipment;
  • parts of machines that are not self-contained containers (housings for pumps, turbines, compressors, or motors);
  • individual medical pressure chambers;
    sprayers;
  • high voltage equipment housings;
  • flexible containers not of metal;
  • silencers;
  • hot water containers.

TR CU 032/2013 applies to pipes, hydraulic valves, boilers, and vessels, with the exclusion of machines and pipes outside the context of the pipes in which they are installed, which is a relevant factor, especially for manufacturers. Foreigners: what is classified as “pressure equipment” requires an EAC certification for each component, as it is not considered as a single machine, as on the contrary academic, for example, for devices regulated by TR CU 010 (“Safety of industrial machinery and equipment “), TR CU 004 (” Safety of low voltage equipment “) or TR CU 012 (” Safety of equipment in classified areas “). The certification of individual pieces involves a high cost for the manufacturer, who must underestimate this aspect well.

EAC certification: declaration or certificate?

Most of the goods produced in the Customs Union countries must undergo EAC certification, and, about pressure equipment, reference is made to the specifications produced in TR CU 032. remember that those not subject to mandatory certification and/or not bearing the EAC logo are considered illegal and, therefore, are subject to fines and/or confiscation.

For products considered “Pressure equipment” and regulated by TR CU 032, the required EAC certification varies according to the risk category to which the piece in question belongs among the four existing ones, which are classified according to the following parameters: pressure, diameter/volume, liquid or gaseous state of the content and level of danger of the latter. The EAC declaration is required for the two lowest risk categories (1 and 2), while for the highest risk categories (3 and 4), the EAC certificate is required. It should be clarified that the two certificates are different and distinct and, in no case can one replace the other.

TR CU 032 certification: types

TR CU 032 provides, as mentioned, proof of conformity. It is accepted by law and can be of 4 types:

  • contract declaration with open date;

  • serial declaration valid for five years;

  • serial certificate valid for five years;

  • contract certificate valid for five years.

For series certifications, an inspection of the production site and a test on a sample are foreseen. At the same time, for those under contract, it is necessary to subject the pressure equipment to the accredited laboratory judgment that will issue a certificate of approval.
