Integrated Radio Modules EMC FAQ

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.

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.

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.

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.
