EU EMC Directive Test Plan Selection

Select EMC tests by starting with the apparatus, its intended use, its electromagnetic environment, and the for emissions and immunity.

This page helps document which harmonised standards, configurations, phenomena, deviations, reports, and technical-file outputs support a Directive 2014/30/EU conformity decision.

Overview

An EMC test plan should explain why the selected standards and assessments cover the apparatus as placed on the EU market. A supports a presumption of conformity only for the covered by the published reference or relevant part; using one is voluntary, but meeting Annex I is mandatory. The manufacturer selects the evidence route and remains responsible for the assessment even when a laboratory or notified body contributes. The plan should identify normal intended operating conditions, , relevant electromagnetic phenomena, and any gaps that need justification in the technical documentation.

Section 1

Start with product function, scope, and essential requirements

First identify whether the item is equipment covered by Directive 2014/30/EU and whether it is apparatus, a component or sub-assembly liable to create or be affected by electromagnetic disturbance, a mobile installation, or part of a fixed installation. Do not select standards before this scope call is made.

Then translate Annex I into test-plan questions: what disturbances can the product generate, what disturbances can it reasonably face in its intended use, and what level of immunity is needed so it operates without unacceptable degradation of that intended use.

  • Record the product name, model or family, hardware and software revisions where they affect EMC conformity, power inputs, ports, cable types, installation assumptions, and intended users.
  • State the intended electromagnetic environment, such as residential, commercial, industrial, power-station, vehicle-related, laboratory, or fixed-installation use, only when supported by product facts and instructions.
  • Check whether another Union act sets more specific EMC requirements for the equipment; if so, separate those requirements from the EMC Directive assessment instead of double counting them.
  • Exclude inherently benign equipment only when the file explains why it cannot generate relevant emissions and can operate without unacceptable degradation under normal intended disturbance.
Section 2

Select standards in the right order

Use harmonised standards as evidence only when the references have been published for the EMC Directive and the selected parts actually cover the product's . A standard can support presumption of conformity only for the requirements it covers.

For a test plan, list the standard reference, edition or dated reference used for the declaration, product function it covers, phenomena covered, ports or interfaces covered, and any left outside its scope.

  • Prefer product-specific standards when they exist for the apparatus and intended environment, then product-family standards, then generic standards for the relevant environment.
  • Use more than one standard when one standard does not cover emissions, immunity, ports, functions, environments, or frequency ranges relevant to the apparatus.
  • For multi-function products, map each primary function to the relevant standard or assessment method instead of assuming one family standard covers the whole product.
  • Check OJEU evidence before release and again when a cited standard is revised, withdrawn, or replaced; if the declaration continues to rely on another technical specification, document why it still meets the without claiming OJEU presumption.
  • Record the Official Journal decision, publication date, withdrawal date if any, and the dated edition actually assessed. A standards owner's newer edition does not by itself change which edition gives presumption of conformity under the EMC Directive.

Section 3

Choose tests from phenomena, ports, and representative configurations

The EMC assessment must consider all normal intended operating conditions. If the apparatus can run in different configurations, the plan should identify the selected by the manufacturer and explain why they cover the relevant emission and immunity risks; different phenomena can require different worst-case configurations.

Take limits, test levels, measurement methods, performance criteria, and setups from the applicable standard or justified technical specification. Identify the source and clause for each value in the test plan, and check that the laboratory procedure implements that basis.

  • Map emissions and immunity separately for mains power, DC power, signal and control lines, telecom or network ports, enclosure/radiated paths, cables, accessories, and installation interfaces.
  • Include low-frequency mains phenomena where the apparatus connects to public low-voltage distribution, high-frequency conducted phenomena for relevant ports, radiated phenomena for electronic or electrical apparatus, transients for mains or nearby-cable conditions, and ESD where the environment can create electrostatic discharges.
  • Define operating modes, loads, software states, communication states, peripherals, cable lengths, earthing, enclosure conditions, and accessories used during testing.
  • Use a worst-case rationale for product families or variants, and keep the rationale separate for phenomena that have different worst cases.
Section 4

Handle partial standards, deviations, and no-standard cases

A test plan should make partial use of a visible. If a standard is applied only in part, the technical documentation needs to specify the parts applied and describe the solutions used for the remaining .

Where no exists, a harmonised standard is not fully applied, the product is too large for the prescribed facility, in-situ testing is used, or another technical method is selected, the plan should show the technical methodology and evidence rather than implying presumption of conformity.

  • Create a deviation table with the omitted or modified clause, reason, affected phenomenon, alternative evidence, responsible approver, and conclusion on how the essential requirement remains met.
  • Do not omit a test merely because it is inconvenient; justify non-performance with design evidence, comparison to similar apparatus, physical characteristics, or another documented assessment method.
  • Use pre-scan results only as screening evidence unless the applied standard or technical method supports that role in the assessment.
  • Escalate to notified-body only when the manufacturer chooses that conformity-assessment route for some or all ; the manufacturer remains responsible for the conformity decision.
Section 5

Outputs to keep in the technical file

The final test-plan package should let a reviewer trace the path from product facts to standards, tests, results, deviations, and declaration language. Keep it with the technical documentation, not only in laboratory email threads.

When the product changes, the standards list changes, or a new variant is added, reopen the test-plan selection record and decide whether the change affects the EMC assessment, reports, declaration of conformity, instructions, or CE marking basis.

  • Scope record: apparatus identification, intended use, intended environment, roles, markets, interfaces, variants, and fixed-installation assumptions.
  • Standards matrix: OJEU publication evidence, standard edition, covered , product functions covered, phenomena covered, and uncovered gaps.
  • Test plan: operating modes, , ports, accessories, cable types and setup, performance criteria, laboratory method references, and acceptance evidence.
  • Deviation and residual-risk record: partial standards, omitted tests, alternative methods, calculations, design precautions, comparison evidence, and approval.
  • Technical-file outputs: risk analysis, design and manufacturing drawings where relevant, test reports, examinations or calculations, EU declaration of conformity references, instructions or restrictions for use, and change-control history.
