Overview

For apparatus under the EMC Directive, the manufacturer must demonstrate compliance with the Annex I essential requirements, choose the applicable assessment route under Article 14, prepare , draw up the EU declaration of conformity, affix CE marking, and keep the required evidence available for authorities. Technical documentation is the controlled file that makes the apparatus's conformity assessable by connecting its design, operation, EMC risk analysis, standards or other solutions, calculations, examinations, test reports, and production controls. A laboratory report can support this work but does not replace it.

Section 1

Choose the EMC conformity assessment route

Article 14 gives the manufacturer two routes for apparatus. The first is Annex II internal production control, where the manufacturer performs the EMC assessment, establishes , controls manufacturing, affixes CE marking, and issues the EU declaration of conformity on its own responsibility.

The second route is Annex III: EU-type examination by a notified body, followed by conformity to type based on internal production control. The manufacturer may restrict the notified-body application to specified aspects of the essential requirements and use Annex II for other aspects. The EU-type examination certificate covers only the aspects examined; the manufacturer remains responsible for production conformity, the declaration, and CE marking.

  • Start with the product category: this page addresses apparatus placed on the market, not a fixed installation file.
  • For Annex II, record the EMC phenomena considered, intended operating conditions, representative configurations, standards or other specifications used, and test or examination results.
  • For Annex III, keep the notified body application scope, EU-type examination certificate, annexes, additions, and the later manufacturing controls that show production remains consistent with the approved type. The Directive defines this as a review of technical design documentation without examination of a specimen, and the manufacturer may request coverage of only specified essential-requirement aspects.
  • Do not treat a voluntary test laboratory report or an unregulated voluntary certificate as a substitute for the manufacturer's assessment, declaration, CE marking decision, and . A body is relevant to Annex III only when it is notified for the EMC Directive and the assessment work falls within its notified scope.
Section 2

Build the technical documentation file

Annex II and Annex III both require that makes it possible to assess apparatus conformity. The file must include an adequate analysis and assessment of EMC risks and cover the design, manufacture, and operation of the apparatus as far as relevant.

A practical EMC technical file should connect the apparatus identification in the declaration, the product drawings and circuit information, the EMC assessment, the standards or alternative specifications used, the test reports, and the manufacturing controls. That link is important because Article 7 requires the manufacturer to keep the and EU declaration of conformity for 10 years after the apparatus has been placed on the market.

  • Identify the apparatus model, type, batch, serial number, or other traceability element used on the product, packaging, or accompanying document.
  • Include a general description of the apparatus plus conceptual design and manufacturing drawings, schemes of components, sub-assemblies, and circuits where relevant.
  • Add descriptions and explanations needed to understand the drawings, schemes, and operation of the apparatus.
  • List harmonised standards applied in full or in part, using references published in the Official Journal, and specify which parts were applied when the standard is only partly used.
  • Where harmonised standards are not used or do not cover all relevant requirements, describe the other technical solutions and specifications used to meet the Annex I essential requirements.
  • Keep design calculations, examinations, EMC test reports, and evidence that manufacturing and monitoring keep produced apparatus aligned with the .

Section 3

Use harmonised standards and test reports carefully

Article 13 gives a presumption of conformity only for equipment that conforms with harmonised standards, or relevant parts of them, whose references have been published in the Official Journal of the European Union. The technical file should therefore show the exact dated standard references used and which essential requirements they cover.

Commission Implementing Decision (EU) 2019/1326 publishes and withdraws EMC harmonised-standard references. Because the published list changes, a release review should confirm the standard reference still supports presumption of conformity for the apparatus and should preserve any transition or withdrawal rationale used for that model.

  • Match each emission and immunity phenomenon to a harmonised standard, part of a standard, or other documented technical solution.
  • Keep complete test reports and not only a pass/fail summary, because Annex II lists test reports as part of the .
  • When a standard is applied partly, record the applied clauses or parts and explain how the remaining essential requirements are met.
  • When the product can operate in different configurations, document the representative configurations assessed for intended use.
Section 4

Prepare the EU declaration, CE marking, and user information

The EU declaration of conformity must state that fulfilment of the Annex I essential requirements has been demonstrated, follow the model structure in Annex IV, contain the elements from the relevant modules, and be kept continuously updated. Where multiple Union acts require an EU declaration for the same apparatus, Article 15 requires a single declaration covering all of them, with the Union acts identified.

CE marking is the visible result of the conformity assessment process. Under Article 17 it must be affixed visibly, legibly, and indelibly to the apparatus or data plate; where that is not possible or not warranted because of the apparatus nature, it goes on the packaging and accompanying documents. The marking must be affixed before the apparatus is placed on the market.

  • Include the Annex IV declaration fields: apparatus model or product identification, manufacturer or authorised representative name and address, sole-responsibility statement, object identification, relevant Union harmonisation legislation, standards or specifications applied, notified body details where applicable, and signing information.
  • Make the declaration traceable to the apparatus and the , including the model, type, batch, serial number, or other identifier used for the apparatus.
  • Provide instructions and information needed for intended use, including specific assembly, installation, maintenance, or use precautions needed to preserve conformity when the apparatus is put into service.
  • If compliance with the Annex I general requirements is not ensured in residential areas, give a clear restriction of use and, where appropriate, put that restriction on the packaging.
Section 5

Keep retention and authority-response evidence

The manufacturer must keep the and EU declaration of conformity for 10 years after the apparatus has been placed on the market. Importers must keep a copy of the EU declaration of conformity for the same period and ensure the technical documentation can be made available to market surveillance authorities on request.

The record should also support formal non-compliance checks. Article 40 lists missing CE marking, missing or incorrect EU declarations, unavailable or incomplete , and absent, false, or incomplete manufacturer/importer information as formal non-compliances that authorities can require the economic operator to end.

  • Keep the final technical file, EU declaration of conformity, CE marking evidence, user instructions, standards list, test reports, and manufacturing-control records for each apparatus model.
  • Preserve supplier and economic-operator traceability records so the supply chain can identify who supplied apparatus and who received it for the required 10-year periods.
  • Track design, component, firmware, manufacturing-process, intended-use, and harmonised-standard changes that could require the EMC assessment, technical file, declaration, marking, or instructions to be updated.
  • For apparatus intended only for incorporation into a particular fixed installation and otherwise not made available on the market, keep the installation identification, EMC characteristics, incorporation precautions, and responsible-person documentation instead of forcing an apparatus CE-marking file where Article 19 provides the specific rule.
