No. Directive 2014/30/EU covers equipment, and equipment means either apparatus or a fixed installation. Apparatus is a finished appliance, or a combination made available on the market as a single functional unit, intended for the end-user and liable to generate electromagnetic disturbance or be affected by it. A fixed installation is a particular combination of apparatus and, where applicable, other devices assembled and intended for permanent use at a predefined location. The consequence is practical: apparatus normally follows the apparatus route, including conformity assessment, EU declaration of conformity, CE marking, identification, traceability, and instructions. Fixed installations must meet the essential EMC requirements and be installed with good engineering practice, but the Commission guide explains that fixed installations are not subject to CE marking, EU declaration of conformity, or a formal EMC assessment before putting into service. - Treat a sold product, single functional unit, component for end-user incorporation, or mobile installation as potential apparatus. - Treat a permanent site assembly, such as an industrial plant, network, PV installation, or building system, as a potential fixed installation. - For fixed installations, keep installation instructions, good-engineering-practice evidence, component intended-use information, and site boundary assumptions.

Often no, but the reason must be EMC-specific. The Directive excludes equipment that is inherently benign in terms of electromagnetic compatibility. The Commission guide says both sides of the test must be met: the item must be incapable of generating or contributing to emissions above a level that prevents other equipment operating as intended, and it must operate without unacceptable degradation in the normal electromagnetic environment. The guide lists examples that may be excluded when they have no active electronic parts, including cables and cabling considered separately, cable accessories, batteries without active electronic circuits, passive antennas, simple resistive loads without automatic switching, and several passive electromechanical items. That does not mean cable choices are irrelevant: the same guide warns that cable characteristics and installation can significantly affect the EMC performance of equipment. - Do not treat a passive item as in scope merely because it is electrical. - Do not treat a cable as irrelevant when it is part of the EMC installation or apparatus instructions. - Record the active-electronics check, emission/immunity rationale, and whether the item is supplied separately or as part of apparatus. Sources for this answer: - [Directive 2014/30/EU on electromagnetic compatibility](https://data.europa.eu/eli/dir/2014/30/oj?ref=sorena.io) - Excludes inherently benign equipment and defines when components or sub-assemblies are considered apparatus. - [European Commission Guide for the EMCD](https://ec.europa.eu/docsroom/documents/33601?ref=sorena.io) - Gives examples of inherently benign products, including separately considered cables and passive components, and warns that cable installation can affect EMC performance. ## What must an EU importer check before placing apparatus on the market? An importer must place only compliant apparatus on the EU market. Before placing apparatus on the market, the importer must ensure that the manufacturer carried out the appropriate conformity assessment, drew up the technical documentation, applied CE marking, supplied required documents, and met identification and manufacturer-contact requirements. If the importer believes the apparatus is not in conformity with the essential EMC requirements, the importer must not place it on the market until it has been brought into conformity. Importers also need their own name or registered trade name or mark and postal address on the apparatus, or where that is not possible, on packaging or accompanying documentation. - Check CE marking, required documents, instructions, manufacturer identification, and importer contact details before sale. - Keep a copy of the EU declaration of conformity for 10 years after the apparatus has been placed on the market. - Ensure the technical documentation can be made available to market surveillance authorities on request.

A failed EMC test, unresolved deviation, or negative notified-body assessment is not something to paper over with a generic certificate. Under the Directive, if a notified body finds that the essential requirements, harmonised standards, or other technical specifications have not been met, it must require corrective measures and must not issue a certificate. For market surveillance, authorities can require the relevant economic operator to bring apparatus into compliance, withdraw it, or recall it where apparatus does not comply. The Directive also calls out administrative non-compliance such as missing or incomplete technical documentation, missing EU declaration, improper CE marking, and missing manufacturer or importer information. - Capture the failed test condition, configuration, standard clause or essential requirement, root cause, corrective action, and retest result. - Do not place or continue making apparatus available when the responsible operator has reason to believe it is non-compliant. - Where a notified body is used, keep the evaluation report, refusal or certificate decision, and any required additional approval for changes.

Radio equipment normally points away from the EMC Directive and toward radio-equipment legislation for the radio product. The Directive text excludes radio equipment covered by the radio-equipment regime, and the Commission EMC guide explains that equipment falling under the Radio Equipment Directive does not fall under the EMC Directive, even though the radio regime includes EMC essential requirements with the same level of protection. For a combined product, separate the radio module, host apparatus, and final marketed configuration. If a radio product is placed on the market under the Radio Equipment Directive, the EU declaration should not cite the EMC Directive for that radio product. If non-radio apparatus or a final combination remains in EMC scope, assess that apparatus or combination on its own facts. - Identify whether the item intentionally emits or receives radio waves for radio communication. - Check whether the final marketed product is a radio product, non-radio apparatus, or a combination containing radio and non-radio elements. - Avoid citing both regimes for the same EMC requirement unless the source for the product category supports that split. Sources for this answer: - [Directive 2014/30/EU on electromagnetic compatibility](https://data.europa.eu/eli/dir/2014/30/oj?ref=sorena.io) - States scope exclusions for radio equipment and the rule that more specific Union legislation displaces EMC Directive requirements for those requirements. - [European Commission Guide for the EMCD](https://ec.europa.eu/docsroom/documents/33601?ref=sorena.io) - Explains the post-RED scope boundary and says radio products under RED should not reference the EMC Directive in the EU declaration of conformity. ## When do modifications make a product a new EMC Directive responsibility? The Directive treats an importer or distributor as the manufacturer when that operator places apparatus on the market under its own name or trade mark, or modifies apparatus already placed on the market in a way that may affect EMC compliance. That means relabelling and technical changes are not just commercial events; they can move manufacturer obligations to the importer or distributor. The Commission guide also explains that substantial changes that may significantly affect EMC compliance, such as EMC characteristics or identification details, can make the apparatus a new product entering the market. Where an EU-type examination certificate was used, modifications that may affect conformity or certificate validity require additional approval from the notified body holding the technical documentation. - Screen firmware, PCB, enclosure, power supply, cable, filter, connector, radio, and configuration changes for EMC impact. - Update the risk assessment, technical documentation, EU declaration, labels, and instructions where the change affects the compliance basis. - If a notified body certificate exists, check whether the change affects the approved type or certificate conditions before relying on it.

No. Harmonised standards are powerful evidence, but only for the essential requirements they cover and only when the relevant references have been published in the Official Journal. Directive 2014/30/EU gives a presumption of conformity for equipment that conforms to harmonised standards, or parts of them, whose references are published in the Official Journal, for the essential requirements covered by those standards or parts. The technical file still needs to show what was applied. Annex II requires a list of harmonised standards applied in full or in part. If harmonised standards were not applied, or were only partly applied, the documentation must describe the solutions adopted to meet the essential requirements and identify the parts of standards that were applied. - Use the current Official Journal publication or Commission implementing decision to verify the standard reference and any withdrawal date. - State whether each standard was applied fully or partly and what essential requirements it covers. - Document deviations, uncovered phenomena, alternative specifications, and risk assessment conclusions.

For apparatus, the technical documentation must make it possible to assess conformity with the relevant requirements and include an adequate analysis and assessment of risks. The Directive lists expected content such as a general description, design and manufacturing drawings, explanations needed to understand drawings and operation, applied harmonised standards or alternative solutions, design calculations and examinations, and test reports. The EU declaration of conformity is separate evidence. The manufacturer must draw it up for an apparatus model and keep it with the technical documentation for 10 years after the apparatus has been placed on the market. Importers must keep a copy of the EU declaration for the same 10-year period and ensure technical documentation can be made available to authorities on request. - Include the product identification, intended use, configurations assessed, electromagnetic phenomena considered, standards list, deviations, and test reports. - Keep the EU declaration of conformity aligned with the apparatus model, applicable Union acts, standards or other specifications, and responsible signatory. - For fixed installations, retain component instructions, good-engineering-practice evidence, site limits, cable and earthing assumptions, and responsible-person records where national implementation requires them.
