TR CU 032/2013: the regulation for EAC Marking of pressure equipment

The Technical Regulation of the Eurasian Union 032/2013 (“О безопасности оборудования, работающего под избыточным давлением” in Russian, “On safety of pressure equipments” in English) is the reference standard for EAC marking of pressure equipment. Depending on the language, it may be also called TR TS 032/2013, or CU TR 032/2013, or TR ZU 032/2013.

This Eurasian regulation bears many similarities with the European Pressure Equipment Directive 2014/68/EU (PED), in particular with regard to the concept of “group”, which is absolutely essential to define the dangerousness (and therefore the certification procedure to be followed) of the work environment of the pressure equipment.

The “Group 1” work environments includes:

a working environment consisting of flammable, oxidizing, combustible, explosive, toxic and highly toxic gases, liquids and vapors in a single-phase state, as well as mixtures thereof.

All other work environments that are not assigned to Group 1 belong to “Group 2”.

The similarities with the European regulations are not limited to the definition of the working environment but cover all the most relevant aspects. There is a difference that is immediately obvious but that is more formal than substantial: in CUTR 032/2013 the pressures are expressed in Megapascals, so it is worth remembering what follows:

1 MPa = 10 bar

Scope of the Regulation

TR CU 032/2013 applies to:

  • pressure tanks (vessels);
  • pipeline;
  • boilers;
  • fittings;
  • valves;
  • pressure maintenance equipment parts.

The Regulation does not apply to all vessels, to all types of boilers, or to all types of pressure equipment. As a general rule, it is necessary a maximum operating pressure a higher than 0.05 MPa, exactly 0.5 bar, like in European regulation.

Other reasons for exclusion from the regulation lie in the structural characteristics of the equipment: the capacity, for vessels and boilers, and the diameter for valves.

Excluded Equipments

The regulation explicitly excludes the applicability to these types of products and devices:

  • Oil and gas pipelines;
  • Gas distribution and consumption networks;
  • Specific equipment for nuclear energy and that operates in a radioactive environment;
  • Ships;
  • Specific equipment for maritime and river and submarine vessels;
  • Braking systems;
  • Specific equipment for airplanes and other aircraft;
  • Defense equipment;
  • Components other than separate vessels (pump or turbine housings, etc.);
  • Hyperbaric chambers;
  • Aerosol equipment;
  • Housings of various types;
  • Exhaust or gas silencers;
  • Containers or siphons for carbonated drinks.

Categories 1, 2, 3 and 4

Depending on the following variables:

  1. Group (1 or 2)
  2. Capacity or diameter
  3. Maximum operating pressure
  4. Fluid type (gas, liquid, vapor)

The Regulation assigns each equipment/device to a category from 1 to 4. In reality, there is a fifth variable to take into account, temperature, but it only influences when it reaches the creep (metal deformation) level. In this case the category of the team is increased by 1 point.

Category 1 and 2 equipments are subject to the EAC Declaration of Conformity.

Category 3 and 4 equipment are subject to the EAC Certificate of Conformity: this means that it will be necessary to carry out an audit of the manufacturing company and carry out tests in a Russian accredited laboratory. In the case of very bulky equipment, the solution may be to carry out a Certification for a single contract or to audit the final installation.

In both cases, the regulation requires to elaborate a Safety Justification.

Category 0: what’s up?

When a pressure equipment does not fall within the ranges of the 4 categories, it is said to belong to “category 0” and therefore requires an Exemption Letter from TR TC 032 in order to be exported to the Eurasian Union.

It will also be necessary to assess the conformity to CU TR 010/2011 (“Safety of machinery”) which is usually directly applicable to many pressure equipment like valves or mechanical pumps, as well as to pressure equipment “modified” and converted into industrial machinery to all effects.

This is the case of vessels manufactured by a leading Spanish company that, depending on whether vessels will end up being used with or without a membrane for osmotic filtration, requests an EAC Declaration of Conformity based on Technical Regulation 010/2011 or not. The vessels themselves would be exempt from the EAC regulation but the presence of a membrane converts them into a “filtration equipment” and therefore subject to the EAC Declaration and marking.

Required Documentation

According to the CU TR 032/2013, these are the needed documents for the issuance of an EAC Certificate of Conformity:

  1. Technical Manual in Russian of all models to be inspected / tested
  2. Safety Justification
  3. Specific technical passports of all models to be inspected / tested
  4. Technical drawings of all models to be inspected / tested
  5. Test reports performed, either NDT (Non-destructive Test) or DT (Destructive-Test)
  6. Material Certificate 3.1
  7. Welding list
  8. WPS (Welding Procedure Specification)
  9. PQR (Procedure Qualification Record)
  10. WPQR (Welder Performance Qualification Record), if applicable
  11. Strenght calculations
  12. Sales contract and invoice (in the case of single contract certification).
