# EMC for products with integrated radio modules

FAQ on when RED or the EMC Directive applies to products with radio modules, and what host-product evidence, technical documentation, DoC records, and test assumptions to keep.

*FAQ* *EU*

## Integrated Radio Modules EMC FAQ

A radio module certificate or supplier declaration does not automatically close EMC for the host product.

Use this FAQ to separate RED from EMC Directive coverage, test the host configuration assumptions, and keep the technical documentation and declaration evidence reviewable.

When a product includes a radio module, start with the final product placed on the EU market. If the final product is radio equipment covered by the Radio Equipment Directive, RED normally covers the electromagnetic compatibility requirements for that radio equipment. If the product has no radio function covered by RED, or another Union act does not lay down the EMC requirements more specifically, the EMC Directive analysis remains relevant for the apparatus or fixed installation.

## Does RED or the EMC Directive apply when a host product includes a radio module?

For current products, the key question is not whether a component is called a module; it is whether the final product made available on the EU market is radio equipment. The Commission EMC guide explains that the EMC Directive no longer applies to products covered by RED, while wireline telecommunications products without a radio function can fall under the EMC Directive if the product is otherwise in scope.

Directive 2014/30/EU also contains the general rule for overlaps: where the essential EMC requirements are laid down more specifically by other Union legislation, the EMC Directive does not apply, or stops applying, for those requirements. That is why a connected host needs a directive map for the final product, not a copy of the module certificate alone.

- Treat Wi-Fi, Bluetooth, cellular, broadcast receiver, and other intentional radio functions as a RED boundary question for the final product.
- Keep the EMC Directive route for non-radio apparatus and for fixed-installation questions where RED does not govern the relevant EMC requirements.
- Do not cite both RED and the EMC Directive as parallel EMC regimes for the same final radio-equipment requirement unless the technical file explains which requirement belongs to which Union act.

Sources for this answer:

- [Directive 2014/30/EU on electromagnetic compatibility](https://data.europa.eu/eli/dir/2014/30/oj?ref=sorena.io) - Supports the EMC Directive scope rule, including the exclusion where more specific Union legislation lays down the relevant essential requirements.
- [European Commission - Guide for the EMCD (Directive 2014/30/EU)](https://ec.europa.eu/docsroom/documents/33601?ref=sorena.io) - Supports the practical RED/LVD/EMCD boundary: products covered by RED are not handled under the EMC Directive for those EMC requirements, while wireline equipment without a radio function can move into LVD/EMCD scope.

## What host-product evidence should be kept?

The host file should let a reviewer connect the radio module evidence to the exact final product placed on the market. Keep the module DoC or supplier declaration, radio and EMC test reports, antenna and installation conditions, integration instructions, bill of materials, photos or drawings, software and operating-mode assumptions, and any deviations from harmonised-standard test methods.

For an unchanged module, document why the host stays within the module supplier's stated installation conditions. If the host changes those conditions, document the technical reasoning, added tests, comparison evidence, or design controls used to cover the changed configuration. The Commission guide states that a final apparatus manufacturer using components from other manufacturers keeps overall control and remains responsible for final-apparatus compliance.

- Map the final product to RED, EMC Directive, LVD, machinery, vehicle, or other applicable Union legislation before drafting the EU declaration.
- Tie each module assumption to host facts: antenna, enclosure, cables, power, ports, grounding, shielding, firmware modes, and intended environment.
- Keep evidence for configurations most likely to cause maximum disturbance and configurations most susceptible to disturbance when multiple normal-use configurations are foreseeable.

Sources for this answer:

- [Directive 2014/30/EU on electromagnetic compatibility](https://data.europa.eu/eli/dir/2014/30/oj?ref=sorena.io) - Supports the manufacturer obligation to draw up technical documentation, carry out conformity assessment, keep the technical file and EU declaration, and account for design, characteristics, and standard changes.
- [European Commission - Guide for the EMCD (Directive 2014/30/EU)](https://ec.europa.eu/docsroom/documents/33601?ref=sorena.io) - Supports host-product responsibility, EMC assessment across intended operating conditions, worst-case configuration documentation, and the need to request component EMC characteristics and incorporation information.

## What should the technical documentation and DoC show?

For an EMC Directive apparatus route, the technical documentation should identify the product covered, describe the apparatus, include drawings or schemes needed to understand the design, list harmonised standards applied and test results, and explain any non-harmonised or partial-standard route used to meet the essential requirements. If Annex III EU-type examination is used, the EU-type examination certificate belongs in the file.

The EU declaration of conformity should identify the apparatus, manufacturer or authorised representative, Union harmonisation legislation, dated harmonised standards or other technical specifications, notified-body information where applicable, and the signer. Where more than one Union act requires a declaration, the EMC Directive allows a single EU declaration covering all relevant Union acts.

- For a RED final product, keep the RED declaration and the supporting file that covers the radio, EMC, safety, and other applicable RED essential requirements.
- For an EMC Directive final apparatus, keep the EMC technical documentation, EU declaration of conformity, CE marking rationale, instructions, traceability information, and any residential-use restrictions.
- For a fixed installation, keep the good-engineering-practice documentation and installation evidence; fixed installations are not handled like ordinary CE-marked apparatus under the EMC Directive.

## How should testing assumptions be documented?

Do not reduce the assessment to a pass/fail test report for the radio module. The EMC assessment should cover relevant emission and immunity phenomena for the final apparatus, its intended use, installation conditions, foreseeable configurations, and electromagnetic environment. Harmonised standards can give presumption of conformity only for the essential requirements and phenomena they cover.

If a harmonised standard is not applied, is applied only in part, or a test is omitted because the manufacturer relies on design precautions, comparison with similar apparatus, physical characteristics, calculations, or other evidence, the technical documentation should explain the deviation and how the essential requirements are still met. For integrated modules, that explanation is where host-specific assumptions belong.

- Record the exact radio modes, power states, ports, accessories, cables, antenna configuration, software version, and loading conditions used in the test or assessment.
- State which phenomena are covered by harmonised standards and which are covered by additional analysis, comparison, design controls, or non-harmonised specifications.
- Reassess when a standard citation changes, the host design changes, or the module supplier changes the allowed installation conditions.
