The energy, chemical, oil and gas processing equipment such as pressure vessels, industrial piping, steam generators, boilers and pressure accessories belongs to the category of overpressure operated devices called pressure equipment.
The pressure equipment is a separate group, which includes potentially dangerous equipment, for which particularly high safety requirements are defined. For this reason, a technical regulation has been developed in the Eurasian Economic Union (EAEU), which sets strict requirements for industrial safety and reliability of pressure equipment.
Legal framework
On July 2, 2013 the technical regulation TR CU 032/2013 On safety of pressure equipment came into force and established standard safety requirements for pressure equipment and its marking. This regulation has been developed in accordance with the European Directives on Pressure Equipment 97/23/EG, 2009/105/EU and 2010/35 /EU.
Application area
The TR CU 032/2013 applies to:
- vessels
- piping
- boilers and steam generators
- pipeline valves
- indicators
- parts of equipment with a safety function
- pressure-bearing components
The TR CU 032/2013 does not apply to:
- main pipeline
- gas distribution network
- equipment for use in the field of nuclear energy
- equipment for use on sea and inland waterways
- brake systems of rail vehicles
- container for use on airplanes
- munitions
- parts of machines which are not self-contained containers (housings of pumps, turbines, compressors or motors)
- medical individual pressure chambers
- sprayers
- housing of high voltage equipment
- non-metallic flexible containers
- muffler and silencer
- containers for carbonated beverages which are intended for final consumption
Conformity assessment
In order to import the pressure equipment to Russia and countries of the Eurasian Economic Union, a certificate of conformity of compliance with the requirements of the Technical Regulation TR CU 032/2013 is required. The pressure equipment is subject to EAC Certification or EAC Declaration according to the TR CU 032/2013.
The equipment and the corresponding conformity assessment procedure are divided into 4 groups of hazard. Less hazardous equipment is classified in category 1, particularly hazardous pressure equipment in category 4. The following criteria are decisive for classification:
- maximum permissible pressure (PS)
- volume (m3) or nominal width (mm)
- the product of maximum permissible pressure and volume or nominal width
Depending on the processing medium (gas or liquid) or group of applied substances are assigned to group 1 or 2 as follows:
- Group 1: hazardous substances (Flammable, oxidizing, combustible, explosive and toxic gases, liquids and vapours)
- Group 2: other substances not mentioned in Group 1

The EAC Certification according to TR CU 032/2013 is needed for pressure equipment of hazardous classes 3 and 4, that are listed in Appendix 1 of the technical regulation.
The EAC Declaration according to TR CU 032/2013 is required for pressure equipment of hazardous classes 1 and 2.
The certification process depends on whether it is a contract delivery, serial production or delivery of components. In case of serial production, a manufacturing audit is usually required.
If pressure devices or assemblies are subject to conformity assessment according to several technical regulations of the EAEU, in which a proof of conformity is required, the products must be certified or declared according to all related technical regulations.
For example, the industrial accessories for pressure equipment are subject to the confirmation of conformity according to TR CU 032/2013, as well as it is subject to the EAC declaration according to TR CU 010/2011 On safety of machinery. If these accessories are equipped with electrical controls, they should also conform to the requirements of TR CU 004/2011 On safety of low voltage systems and TR CU 020/2011 On electromagnetic compatibility.
In contrast to many other technical regulations, TR CU 032/2013 does not provide the possibility to replace the EAC declaration by the EAC certification at the request of the applicant.
The proof of conformity is issued for up to five years.
Required documents:
- general description of the pressure equipment
- vessel passport
- safety justification with risk assessment
- instruction manual
- strength calculations
- technical passport of protective device
- technical drawings
- test reports
- quality certificates and approvals at hand
- ISO 9001 Certificate
EAC conformity assessment schemes
Schemes of EAC declaration
| Scheme | Description |
|---|---|
| 1D | is intended for series production for equipment of the hazard class 1,2. This scheme requires the type examination of product samples. Type examination of product samples is carried out by the manufacturer. |
| 2D | is intended for a batch delivery or a single delivery for equipment of the hazard class 1,2. This scheme requires the type examination of product samples. Type examination of product samples are carried out by the manufacturer. |
| 3D | is intended for series production for equipment of the hazard class 1,2. This scheme requires product samples to be tested by a laboratory accredited by the EAEU. |

Conformity assessment of parts of equipment with a safety function and indicators
Parts of equipment with a safety function and indicators are also subject to the requirements of TR CU 032/2013.
Parts of equipment with a safety function are devices that are designed to protect the pressure equipment if the permissible pressure or temperature limits are exceeded. Parts of equipment with a safety function belong to the 4th category and are subject to EAC certification according to TR CU 032/2013.
Indicators are such devices as sight glasses, level indicators, gas and liquid flow indicators and other similar technical devices that are not measuring devices.
Measuring devices such as termometers, barometers, vacuum meters and gas meters are not subject to any EAC conformity assessment. An exemption letter must be issued for these devices instead. Please note that measuring devices may require a metrological approval certificate.
Conformity assessment of pressure equipment, the working media of which is in the liquid and gaseous state
When assessing the conformity of pressure equipment, the question often arises of how to choose the form of conformity confirmation if the working medium is in two states: liquid and gaseous. Rostekhnadzor answered this question.
The main danger for pressure equipment is the energy reserve of the working medium, which is located in the closed space of the container body, the value of which depends on the pressure, temperature, volume, properties and physical state of the medium.
The greatest risk is the working medium in the gaseous state. A medium in the gaseous state has the property of reducing its volume with increasing pressure up to a liquefied state and increasing the pressure with increasing temperature. If the pressure equipment is destroyed during operation, an uncontrolled process of pressure drop occurs with an increase in the volume of the media pressurized in it in a gaseous, liquefied or dissolved state, which leads to further destruction and the formation of a pressure wave.
Since the main criterion in the Technical Regulation TR CU 032/2013 is pressure, the conformity assessment of pressure equipment is determined as follows:
- The category of devices that are under the pressure of media in two aggregate states (liquid and gas) should be determined according to the part of the medium that gives the highest category and poses the greatest risk
- The category of equipment operating under the pressure of liquefied gases is determined by gas
Authorized representative
The manufacturer, which is not based in one of the member states of the Eurasian Economic Union, is not entitled to request the conformity assessment of pressure equipment and pressure vessels to comply with the requirements of TR CU 032/2013 On safety of pressure equipment.
In order to be able to carry out a conformity assessment, the foreign manufacturer must commission an authorized representative in one of the member states of the Eurasian Economic Union. This then represents the foreign manufacturer's interest in working with the certification bodies of the Eurasian Economic Union with regard to the safety and quality of products and compliance with technical regulations.
EAC Marking
The pressure equipment that conforms to the requirements of TR CU 032/2013 should be marked with the EAC mark of the EAEU. The placing of products on the market without relevant mark can be punished with a fine and confiscation.
Period of validity of EAC conformity assessment certificates for pressure equipment
The validity period of the EAC certificate or EAC declaration for pressure equipment differs depending on the applied technical regulations, the selected scheme, the type of production (serial production, individual delivery, etc.) and equipment and ranges on average from one to 5 years. Those parameters are determined in the respective technical regulation.
Duration and costs for EAC certification
The duration and costs associated with an EAC certificate application for pressure equipment depend on several different factors, such as the classification of the product, any required laboratory checks and the complexity of all examinations. As such the exact conditions of the EAC certification are always determined individually based on the required documentation.
Please note that an application for an EAC certificate can takeseveral weeks to process.
Delivery of the documentation
If you order the EAC Certificate on Pressure Equipment, you will receive a copy of it via email immediately after our successful certification procedure. The original document and two certified copies will be sent by post.
