There will always be strong demand for pressure equipment in the Eurasian market: water and energy systems cannot function without them.

What is the scope of CU TR 032/2013 on pressure equipment?
CU TR 032/2013 “On the safety of pressure equipment” sets the rules for the design, manufacture, and circulation of pressure equipment in the Eurasian Economic Union (EAEU). It covers a wide range of products that operate under a pressure greater than 0.05 MPa (0.5 bar) and above specific volume and diameter thresholds defined in the regulation.
The regulation applies to:
- Pressure vessels such as tanks, receivers, and autoclaves.
- Boilers, including hot water and steam boilers.
- Piping systems intended to transport gases, vapors, and liquids under pressure.
- Safety accessories such as valves, rupture discs, and monitoring devices.
- Fittings and assemblies forming part of a pressurized system.
Excluded from its scope are items like medical pressure chambers, equipment for nuclear plants, aviation and maritime pressure systems, and main gas pipelines.
The objectives, basic concepts, and the standards used are essentially the same as those applied under the EU Pressure Equipment Directive (PED).
What are the basic concepts of CU TR 032/2013?
The conformity assessment of pressure equipment under CU TR 032/2013 is based on four key parameters:
- Group (1 or 2) – Group 1 includes hazardous fluids (toxic, flammable, oxidizing, explosive), while Group 2 covers all other media.
- Capacity or diameter – For vessels, the internal volume is considered; for pipelines, it is the nominal diameter.
- Maximum operating pressure – The highest pressure at which the equipment is designed to operate safely.
- Fluid type (gas, liquid, vapor) – The physical state of the medium being contained or transported.
These parameters, when combined, determine the category of the equipment (0, 1, 2, 3, or 4). The higher the category, the stricter the requirements in terms of design validation, testing, and conformity assessment procedures.
Actually, a fifth parameter may also come into play: temperature. It only becomes relevant at creep conditions (metal deformation), in which case the equipment category is increased by one level.
Which EAC certifications apply to pressure equipment?
Category 1 and 2 equipment → subject to an EAC Declaration of Conformity. In some cases, it is possible to follow the 1D scheme, which allows the manufacturer to register the Declaration based on its own test reports or those from a technical laboratory not accredited in the EAEU.
Category 3 and 4 equipment → require an EAC Certificate of Conformity. This involves an audit of the manufacturing company and testing in an accredited laboratory in the EAEU. For very large vessels or installations, alternatives may include a single-contract certificate or auditing the final installation on-site.
In both cases, CU TR 032/2013 requires a Safety Justification (Обоснование безопасности), a technical document that demonstrates compliance with safety requirements.
Category 0 equipment → when a vessel or component falls outside the thresholds of categories 1-4, it is assigned to “Category 0.” These products are not directly regulated under CU TR 032/2013, and this condition must be confirmed with an Exemption Letter.
This document is normally sufficient for customs clearance, provided that CU TR 010/2011 (Machinery Safety) is not applicable. CU TR 010 often applies to pressure-related components such as valves or pumps, or to equipment that incorporates membranes, filters, or other devices that effectively transform a simple vessel into industrial machinery. In such cases, an EAC Declaration of Conformity under CU TR 010/2011 is required.
What documents are required for EAC certification of pressure equipment?
To certify pressure equipment under CU TR 032/2013, you’ll need a comprehensive documentation package, which includes:
- Technical Manual in Russian of all models to be inspected / tested.
- Safety Justification.
- Specific technical passports of all models to be inspected / tested
- Technical drawings of all models to be inspected / tested.
- Test reports performed, either NDT (Non-destructive Test) or DT (Destructive-Test).
- Material Certificate 3.1.
- Welding list.
- WPS (Welding Procedure Specification).
- PQR (Procedure Qualification Record).
- WPQR (Welder Performance Qualification Record), if applicable.
- Strenght calculations.
- Sales contract and invoice (in the case of single contract certification).
