An EAC certificate for a pressure vessel cannot be selected from the product name alone. The decision starts with the vessel’s working pressure, volume, temperature, medium, material, intended use and supplied assembly. These details are used to establish whether the relevant regulation applies, whether an exclusion is relevant and which conformity assessment form should be considered.
For pressure equipment supplied to the EAEU market, the practical route is to verify the product boundary first, classify the equipment using its actual design information and then identify the applicable assessment form. Site-level industrial safety obligations must be considered separately. They are not replaced by conformity assessment for the supplied product.
Does the EAEU conformity process apply to this vessel?
The first question is not whether the equipment is called a vessel, tank or pressure vessel. The first question is whether the product falls within the relevant technical regulation and whether an exclusion affects the assessment. That decision depends on the equipment’s technical characteristics and intended use.
A name used in a catalogue or purchase order is not enough to establish the route. The same general product description may cover equipment with different pressure, volume, temperature or medium characteristics. The supplied assembly can also change the product boundary that needs to be reviewed.
Do not treat every tank as pressure equipment. Do not treat every pressure vessel as a storage tank. The assessment must follow the actual design and operating information. This avoids a threshold calculation based on assumptions and prevents pressure equipment from being conflated with storage tanks that are not under pressure.
Which product information determines the decision?
The review requires a defined set of product inputs. The supplier should provide the information as it applies to the exact model or supplied configuration.
- Working pressure, showing the pressure for which the equipment is intended to operate.
- Volume, referring to the relevant vessel or equipment configuration.
- Temperature, including the operating conditions needed for the assessment.
- Medium, identifying what the vessel contains or handles.
- Material, covering the materials used in the pressure-containing equipment.
- Intended use, explaining how and where the equipment is designed to be used.
- Supplied assembly, describing whether the vessel is supplied alone or as part of a wider assembly.
These inputs are not a formality. They provide the basis for checking scope, exclusions and classification. If one of them is missing, the assessment route may remain unresolved. A product drawing without operating data may describe the shape of the equipment but not establish the conformity path.
What should the supplier prepare before requesting a review?
Prepare a consistent technical information set before asking for an EAC assessment. The information should describe one defined product or one clearly identified product family. If several versions are involved, separate the differences that affect working pressure, volume, temperature, medium, material, intended use or supplied assembly.
The supplier should check that the technical description, operating data and supply configuration refer to the same product. Inconsistent information can make the classification uncertain. For example, a vessel described as a standalone unit in one document but supplied as part of an assembly in another requires clarification before the route can be selected.
Provide the information in a form that can be reviewed without guessing. State the working pressure and temperature rather than using a general description such as “standard service”. Identify the medium rather than describing it only as a process fluid. Explain the intended use in practical terms. State whether the supplied item includes associated equipment that forms part of the delivered assembly.
How is the applicable assessment form selected?
The assessment form is selected after the regulation and any relevant exclusions have been checked. Classification follows from the actual product information. It should not be chosen solely because the supplier has used the same form for another vessel.
The decision path is straightforward:
- Define the product and the supplied assembly.
- Collect working pressure, volume, temperature, medium, material and intended use.
- Check whether the relevant regulation applies to that product.
- Review possible exclusions before making a classification decision.
- Use the verified design information to determine the classification.
- Select the applicable conformity assessment form for the established route.
This order matters. Classification cannot be treated as a starting assumption when the scope and exclusions have not been checked. Equally, the existence of pressure in a system does not by itself establish that a particular certificate is required.
Is an EAC certificate always the correct route?
No conclusion should be made from the phrase “EAC certificate for pressure vessels” alone. The correct assessment form depends on the applicable regulation, the product’s classification and any exclusions. The review may therefore confirm that a certificate is the relevant form, or it may identify another applicable assessment form.
The safe commercial approach is to request a route review rather than order a document by name. This prevents the supplier from paying for an assessment that does not match the product. It also avoids presenting a certificate as a substitute for information that is still needed to establish the equipment’s status.
Where the supplier already has a proposed assessment route, it should be checked against the actual pressure, volume, temperature, medium, material, intended use and assembly. A previous route may be relevant background, but it does not replace the product-specific review.
What is the difference between conformity and site safety?
Conformity assessment concerns the product placed on the EAEU market under the applicable technical requirements. Site-level industrial safety obligations concern the use and operation of equipment at a particular site. These are separate questions.
A completed product conformity assessment does not, on its own, answer every question about installation, operation or industrial safety at the site. Conversely, a site safety review does not establish the product’s conformity route. The supplier should keep these workstreams separate when defining the scope of the service.
This distinction is particularly important where the vessel is supplied as part of an assembly. The product assessment should identify what is being supplied. Site-level questions should then be considered separately for the place and conditions of use. Neither part should be inferred from the product name alone.
What does the conformity review service do?
The service starts by converting the supplier’s product description into a defined assessment question. The review team checks the supplied information, identifies gaps and considers the regulation and exclusions relevant to the product. It then uses the verified inputs to support classification and selection of the applicable assessment form.
The service can cover the following work:
- Reviewing the product description and supplied assembly.
- Checking whether the information covers working pressure, volume, temperature, medium, material and intended use.
- Separating pressure equipment from storage tanks that are not under pressure.
- Identifying where missing design information prevents a reliable classification decision.
- Reviewing the regulation scope and relevant exclusions.
- Setting out the conformity route that follows from the verified product inputs.
- Keeping product conformity separate from site-level industrial safety obligations.
The output should be practical. It should explain what has been established, what remains open and which product information supports the decision. It should not replace missing design data with a guessed threshold calculation or an assumed product category.
Who provides the information and who makes the assessment decision?
The supplier controls the accuracy of the product information. It must describe the equipment as it will actually be supplied and used. The supplier should also identify differences between models, configurations or assemblies instead of presenting them as one identical product when their operating inputs differ.
The conformity review team examines the information against the relevant scope, exclusions, classification logic and assessment form. Its role is to structure the decision and identify information that needs clarification. It cannot establish a reliable route from a product name where the technical inputs are absent.
Where the equipment is supplied as part of a wider assembly, the parties should agree what is included in the review. The supplied assembly must be described clearly enough to determine the product boundary. This prevents a vessel being assessed in isolation when the commercial supply covers a wider configuration, or a wider assembly being assumed when only the vessel is supplied.
What affects a quotation for this service?
A quotation depends on the information available and the scope of the product review. It should be based on the actual equipment rather than on the generic phrase “pressure vessel”. The following factors normally shape the quotation discussion:
- Whether the product is a single vessel or a supplied assembly.
- Whether the working pressure, volume, temperature, medium, material and intended use are already available.
- Whether the product boundary is clear or requires clarification.
- Whether exclusions need to be reviewed.
- Whether one configuration or several product variants are included.
- Whether the supplier needs only a route review or also support with the selected conformity assessment process.
- Whether separate site-level industrial safety questions have been included in the requested scope.
Give these details when requesting a quotation. A clear scope reduces rework because the service can be planned around the actual product inputs. If the information is incomplete, the quotation should identify the assumptions or information gaps instead of treating them as resolved technical facts.
How should a supplier decide between two similar products?
Compare the products by their assessment inputs, not by their commercial names. Two vessels may have similar dimensions but different working pressure, temperature, medium, material or intended use. Those differences can affect the classification and the applicable assessment form.
Decision example. A supplier has one vessel design offered in two configurations. In the first configuration, the vessel is supplied alone. In the second, it is supplied with associated equipment as a defined assembly. The supplier should not assume that one review automatically covers both. It should submit the operating inputs for each configuration and explain what is included in each supply. The review can then determine whether the product boundary, classification or assessment route differs.
This example does not require a threshold calculation. It shows why the supplied assembly is a specific decision input. The same approach applies when the medium, temperature or intended use changes between variants. Provide the differences first, then ask for the route to be confirmed.
What should be checked before the assessment is started?
Use the following preparation check before sending the product for review:
| Check | What to confirm |
|---|---|
| Product identity | The description refers to the exact vessel or product family being supplied. |
| Operating data | Working pressure, volume and temperature are stated for the relevant configuration. |
| Contents | The medium is identified clearly. |
| Construction | The relevant material information is available. |
| Use | The intended use is described in practical terms. |
| Supply boundary | The supplied vessel or assembly is defined. |
| Scope | Potential exclusions and the applicable regulation are ready for review. |
| Safety distinction | Site-level industrial safety questions are kept separate from product conformity. |
If a row cannot be completed, mark it as open. Do not insert an estimated value merely to complete the table. Actual design information is needed before a classification or threshold-related decision can be made.
What mistakes can delay the route decision?
The most common problem is treating the product name as the complete technical description. A second is requesting a certificate before checking whether that is the applicable assessment form. A third is using a classification from another product without confirming that the pressure, volume, temperature, medium, material, intended use and supplied assembly are the same.
Another risk is combining product conformity with site-level industrial safety. These areas may be connected in practice, but they answer different questions. Keeping them separate makes the requested service clearer and prevents a conformity document from being presented as a complete site compliance decision.
Finally, avoid calculations based on missing design information. If the actual inputs are not available, the correct next step is to request them. A precise-looking result based on assumptions is not a reliable assessment basis.
What does the supplier receive from a completed review?
The service should give the supplier a documented route for the defined product scope. It should identify the product inputs used, the regulation and exclusions considered, the classification basis and the applicable assessment form indicated by those facts.
Where information is missing, the outcome should state what needs to be supplied before the decision can be completed. Where the product is part of an assembly, the outcome should make the reviewed boundary clear. Where site-level industrial safety matters fall outside the product review, they should be identified as a separate area rather than silently included.
This gives the supplier a practical basis for the next conformity step. It also provides a clearer scope for any quotation, technical file review or further assessment work that follows.
Frequently asked questions
Can I request an EAC certificate using only the vessel name?
No. The vessel name does not establish the applicable route. Provide working pressure, volume, temperature, medium, material, intended use and supplied assembly. The regulation and exclusions must then be reviewed before the applicable assessment form is selected.
Do I need to calculate a threshold before supplying the product data?
No threshold calculation should be made without actual design information. First collect the product inputs and confirm the scope. A calculation based on assumed pressure, volume, temperature or other data may lead to the wrong classification.
Are pressure vessels and storage tanks assessed in the same way?
They should not be conflated. The review must establish whether the equipment is under pressure and whether the relevant regulation and exclusions apply. A storage tank that is not under pressure should not be treated as pressure equipment merely because it is called a tank.
Does product conformity cover industrial safety at the installation site?
No. Product conformity and site-level industrial safety obligations are separate. The product review addresses the conformity route for the supplied equipment. Site-level obligations require separate consideration for the place and conditions of use.
Start with the actual product inputs, define the supplied assembly and confirm the assessment route before requesting an EAC certificate.
a welded compressed-air receiver
Use the receiver’s design pressure and volume, its medium and design temperature to establish the pressure-equipment category. Match the welding and pressure-test records to the vessel and its serial identification before assembling the technical file.
Use the applicable classification tables in TR CU 032/2013 once the medium and design data are confirmed. Then check the conformity form for the resulting category and whether the vessel is supplied as part of a larger assembly.
