TR CU 032/2013: What It Is and What It Requires
TR CU 032/2013 governs equipment operating under excess pressure above 0.05 MPa across the EAEU: pressure vessels, boilers, pipelines, safety devices, fittings and assemblies containing pressure components. It binds manufacturers, importers, suppliers and operators alike, and conformity is confirmed by certificate or declaration according to hazard category.
What does the regulation govern?
Equipment operating under excess pressure above 0.05 MPa, anywhere in the EAEU. That covers pressure vessels, boilers, pipelines, safety devices, fittings, and assemblies that include pressure components.
It binds four groups: manufacturers, importers, suppliers, and the organisations operating such equipment.
Its purpose is stated in terms of what it is trying to prevent, accidents, ruptures, leaks and hazardous situations arising from the use of pressure equipment. That matters because the equipment is concentrated in high-risk industries: energy, oil and gas, chemical production, heat power engineering, mechanical engineering and municipal systems. A design or operational error there does not stay small.
What does it require?
| Area | Requirement |
|---|---|
| Materials | Chemical resistance, durability, stability under temperature and pressure variation |
| Design | Strength calculations, load modelling, structural validation across operating modes |
| Integrity | Tightness, correct functioning of safety valves, stability of welded joints, reliability of fittings |
| Testing | Hydraulic, pneumatic, climatic, vibration and others by purpose |
| Marking | Working and maximum pressure, temperature, hazard category, date of manufacture, serial number |
| Protection | Mandatory installation of protective devices |
| Quality | Control systems, stability of characteristics, documentation kept current |
Materials and strength
The regulation is specific about material selection criteria, chemical resistance, durability, and stability when temperature and pressure vary. Alongside that sit the strength calculations: load modelling and structural validation across the different operating modes the equipment will see.
Strength is not the only property assessed. Tightness, the correct functioning of safety valves, the stability of welded joints and the reliability of fittings are all in scope.
Testing
All equipment undergoes mandatory testing, hydraulic, pneumatic, climatic, vibration and others depending on purpose. The point of the range is to evaluate real-world performance rather than a single design case.
Marking
Each product must show its working and maximum pressure, its temperature, its hazard category, the manufacturing date and the serial number. This is the information that prevents errors during installation and maintenance, when whoever is working on the equipment has the nameplate and nothing else.
How is conformity confirmed?
By certification or declaration, according to the hazard category.
- Certification applies to the higher hazard categories. It brings inspection control, expert visits, and regular confirmation that production remains stable.
- Declaration serves the less dangerous categories. It still requires a full documentation package and successful testing.
In both cases accredited laboratories run the tests and the conformity assessment, and the results go into protocols and the technical documentation.
What does the manufacturer have to do afterwards?
Three obligations that outlast the certificate: implement quality control systems, keep the characteristics of the equipment stable, and update the documentation in good time. Conformity under this regulation is a state the manufacturer keeps up after the certificate is issued.

Frequently asked questions
Who does TR CU 032/2013 bind?
Manufacturers, importers, suppliers and the organisations that operate the equipment within the EAEU. It is not only a market-entry rule: an operator running pressure equipment inside the union is subject to it as much as the company that built or imported the item.
What decides certificate versus declaration?
The hazard category of the equipment. Certification applies to the higher categories and brings inspection control, expert visits and periodic confirmation that production remains stable. Declaration serves the less dangerous categories, but still requires a full documentation package and successful testing.
What must the marking show?
Working and maximum pressure, temperature, hazard category, manufacturing date and serial number. The purpose is practical: it prevents errors during installation and maintenance, when the person handling the equipment has no access to the technical file.
