Certification under TR CU 020/2011 “Electromagnetic Compatibility of Technical Means”

TR CU 020/2011 is a key EAEU technical regulation that establishes electromagnetic compatibility (EMC) requirements for technical means. If a product falls within its scope, conformity assessment becomes a mandatory condition for lawful import and sales in the EAEU countries.

We work with European manufacturers, brands, and trading companies seeking access to the EAEU market. It is important to understand that the familiar European compliance logic, including CE, and the EAEU logic are different systems. Therefore, our task is not to “issue a document”, but to build the procedure so that it remains robust during inspections: the correct form – certificate or declaration – the correct scheme, testing to the required standards, and a technical file without weak points.

What is TR CU 020/2011 and what is it for?

In practical terms, electromagnetic compatibility answers two questions: does the product create inadmissible interference, and is it resistant to external influences that are possible during normal operation? This matters not “in theory”, but at specific points: at the border, during market surveillance, at the B2B client’s site, in tenders, and in procurement.

A correctly issued document under TR CU 020/2011 is not a “tick-box”, but an instrument of market access and risk management: it must be verifiable and logically consistent – from product identification to test reports and correct registration in the register.

Which products are subject to assessment under TR CU 020/2011?

Mistakes most often begin with oversimplification “by product name”. In the EAEU, intended purpose, the electronic part, configurations, completeness, and supply format matter more: the product is supplied as an individual unit, as a set, as a module, or as part of equipment. Even closely named positions may require different conformity assessment logic – this is normal practice for EMC.

To determine whether the regulation applies and which form of assessment is required, at the outset a minimum is sufficient: what the product is, how it is used, which modifications exist in the range, and how supplies are organized. After that, it becomes clear which requirements actually apply and how to build the procedure without rework.

Typical product examples

• Drives
• Inverters
• Controllers
• Power supplies
• Servers
• Routers
• Control panels
• etc.

Exceptions and borderline cases

There are product categories and scenarios in which the applicability of TR CU 020/2011 is better confirmed by actual intended purpose and configuration. This is especially important when the product is supplied as part of a system, has several configurations, or the set of accessories/cables changes.

In practice, we check this by the following indicators:

1. Not by name, but by intended purpose
2. Configurations and operating modes matter
3. Cables and accessories are taken into account
4. Modules require correct identification
5. A model line requires separate logic

Certificate or declaration: which to choose under TR CU 020/2011?

The key point is to determine the form of conformity assessment correctly. The legal mechanics are straight forward:

• EAEU Certificate of Conformity issued through an accredited certification body, which issues the certificate.
• EAEU Declaration of Conformity issued in the applicant’s name, the declaration is registered by the applicant, and responsibility for the correctness of the evidence lies with the applicant.

We help select the form and scheme so that you do not end up in a situation where “the document exists, but it is weak”: an unsuitable scheme, disputable wording, irrelevant testing standards, or an incomplete technical file.

When is a certificate of conformity required?

A certificate is chosen when certification is specifically required for the given type of product and regulatory requirements, and also when the business scenario implies increased attention to the evidence base, for example supplies to large facilities or under strict procurement procedures. In practice, the decision is always tied to product identification, the supply scenario, and the selected scheme.

When is a declaration of conformity sufficient?

A declaration is suitable when the regulation allows declaration for your category of technical means. Here it is critical not to “oversimplify” the process: even with a declaration, the robustness of the document is determined by how correctly the evidence is assembled and how completely EMC testing is covered.

Conformity assessment schemes: how to choose without errors

Under TR CU 020/2011, the choice of scheme is not a “formality”, but a link to your supply scenario and evidence base. In practice, we start from how exactly you place the products on the EAEU market:

• Batch supply – when the document is needed for a specific contract and a specific batch.
• Serial supplies – if you plan regular import/sales and need a scheme for stable production.
• Single product – when the supply is one-off, for example for a project or for a specific customer.
• Importer as applicant – relevant if the manufacturer is not present in the EAEU and an applicant/representative is required.
• OEM / rebranding – if the brand/marking changes and it is important to link the documents to the product correctly.
• Model line – when there are modifications/versions and it is necessary to describe the model boundaries correctly so that the document “holds up” during inspection.

How we determine exactly what you need

We start with diagnostics. It is a quick stage that saves weeks of corrections: we define the intended purpose and characteristics of the product, the scope of supply, the supply scenario – batch or serial production – the state of the documentation, and the project roles, including who will act as the applicant and whether an authorized representative in the EAEU is required.

Diagnostic outcome

We define the requirements for your product before the work begins:

• Required document
• Suitable scheme
• Scope of testing
• Document package
• Marking requirements
• Risks and corrections
• Timeline plan

Stages of obtaining a certificate/declaration under TR CU 020/2011

We build the procedure consistently and in a verifiable way. At the start, we collect the basic package and compare it with the requirements of the regulation and the selected scheme. If the documentation is still rough – which is typical for new models or OEM supplies – we help bring it into working shape, because this is faster and more reliable than correcting errors after testing.

Next, we organize testing in an accredited laboratory: we agree the test program, support preparation of the sample, and define configurations and operating modes so that the reports cover the EMC requirements specifically for your product and supply. The final step depends on the form: the certificate is issued by the certification body, and the declaration is registered by the applicant in accordance with the established procedure.

EMC registration process

We control the correctness of the information so that the document is valid and verifiable in the register.

EMC testing: what is checked and what is important not to miss

For EMC, details that often get “lost” without proper support are critical: product configurations, the set of cables and accessories, operating modes, test conditions, and assessment criteria. If a report formally exists but the configuration does not correspond to the supply, or the operating modes do not reflect real operation, the document becomes vulnerable during inspections.

To ensure that the reports really cover the requirements of TR CU 020/2011, we define the following checkpoints in advance:

Test program
We select tests for the product and scheme so that the EMC requirements are covered without unnecessary steps.

Sample configuration
We define the completeness, cables, and accessories so that the report corresponds to the supply and the application.

Operating modes
We check the most heavily loaded modes that influence emissions and immunity in real life.

Compliance criteria
We make sure that the reports contain correct criteria and conclusions suitable for document registration.

Management of modifications
If changes are needed, we coordinate them so that repeated testing is minimal and justified.

Timing and cost: what affects the price?

We do not tie the service to a specific country – we work with European clients “for the EAEU market”. Therefore, timing and cost are determined not by geography, but by the volume of work and the evidence required.

In practice, the price is affected by the form of assessment – certificate or declaration – the scheme – batch or serial – the scope of testing, and the readiness of the technical documentation. The more accurately the applicability of the requirements is defined and the better the source materials are, the fewer unnecessary steps there are and the faster the project moves.

Advantages of correct registration under TR CU 020/2011

A correctly issued EMC document is not a “tick-box”, but practical protection of the supply and sales chain. It reduces the likelihood of stops and questions where the consequences are most tangible: at the border, during inspections, and at the client’s site.

What the document provides

It simplifies market access and reduces risks at every stage of supply:

Legal placing on the market

Fewer risks at the border

Calmer market surveillance

Easier B2B sales

More transparent for distributors

More reliable in tenders

How to choose an accredited body and laboratory?

The quality of the result largely depends on who performs the conformity assessment and how the evidence base is assembled. The guideline is simple: accreditation in the required field, practical experience with your type of product, clear communication, and the ability to work with configurations and modifications.

If you are promised “everything in one day without documents”, this almost always means the risk of a weak result. In the EAEU, weaknesses show up later – when the document starts to be checked against the reports, marking, and the logic of product identification.
