EMC Directive 2014/30/EU — the complete guide

Directive 2014/30/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to electromagnetic compatibility (the EMC Directive) replaced the earlier Directive 2004/108/EC with effect from 20 April 2016. It is part of the EU's New Legislative Framework (NLF) family of product directives, sharing common definitions, conformity assessment modules, and obligations with directives like the LVD (2014/35/EU), the Radio Equipment Directive (2014/53/EU), and the upcoming Cyber Resilience Act.

If your apparatus contains any electronic component that can emit or be affected by electromagnetic disturbance — which in practice means almost every powered product — and it is not exclusively covered by a more specific directive, the EMC Directive applies. The legal text, including all articles and annexes referenced below, is published on EUR-Lex at eur-lex.europa.eu/eli/dir/2014/30/oj.

Scope and exclusions (Article 2)

The EMC Directive applies to equipment, a term that covers both apparatus (any finished appliance or combination thereof made commercially available as a single functional unit) and fixed installations (a particular combination of several types of apparatus assembled in a given location). The list of exclusions in Article 2(2) is short but important:

• Radio equipment covered by the Radio Equipment Directive 2014/53/EU. RED Article 3.1(b) carries the EMC essential requirements forward for radio products, so a connected radio device is assessed under RED, not under 2014/30/EU.
• Aeronautical products in the scope of Regulation (EC) No 216/2008.
• Amateur radio equipment not available on the market.
• Equipment whose physical characteristics make it inherently benign — incapable of generating or contributing to electromagnetic emissions exceeding the level allowing radio and telecommunication equipment to operate as intended, and able to operate without unacceptable degradation in the presence of electromagnetic disturbance.
• Custom-built evaluation kits used by professionals at R&D facilities.

If your product is a connected radio (Wi-Fi, BLE, LoRa, cellular), you will rarely have to read 2014/30/EU directly — see our RED Annex IV walkthrough instead.

Essential requirements (Article 6 and Annex I)

Article 6 is one sentence:

"Equipment shall meet the essential requirements set out in Annex I."

Annex I splits into two parts. Part 1 (Apparatus) requires that equipment be designed and manufactured, having regard to the state of the art, so that:

"(a) the electromagnetic disturbance generated does not exceed the level above which radio and telecommunications equipment or other equipment cannot operate as intended; (b) it has a level of immunity to the electromagnetic disturbance to be expected in its intended use which allows it to operate without unacceptable degradation of its intended use."

Part 2 (Fixed installations) requires that a fixed installation be installed "applying good engineering practices and respecting the information on the intended use of its components" so that the apparatus-level requirements in point 1 are met.

In practice, "the state of the art" is interpreted through the harmonised standards listed in the Official Journal — which confer a presumption of conformity when applied correctly.

Conformity assessment (Article 14, Annexes II and III)

Article 14 of the EMC Directive offers exactly two procedures for apparatus:

For a broader overview of the New Legislative Framework module set (Module D, E, F, G, H), see our conformity assessment modules A to H guide.

Annex II — Module A in detail

Under Annex II the manufacturer (a) performs the EMC assessment of the apparatus taking into account all intended operating conditions, (b) establishes the technical documentation listed in Annex II point 2, (c) ensures and declares that the apparatus satisfies the essential requirements, and (d) affixes the CE marking. The Annex II technical documentation list reads:

• a general description of the apparatus;
• conceptual design and manufacturing drawings and schemes of components, sub-assemblies, circuits, etc.;
• descriptions and explanations necessary to understand those drawings and schemes and the operation of the apparatus;
• a list of the harmonised standards applied in full or in part, the references of which have been published in the Official Journal of the European Union;
• where harmonised standards have not been applied or have been applied only in part, descriptions of the solutions adopted to meet the essential requirements;
• results of design calculations made, examinations carried out;
• test reports.

Annex III — Module B + Module C

When the manufacturer prefers third-party scrutiny, a notified body performs Module B (EU-type examination) and issues an EU-type examination certificate. The manufacturer then applies Module C (conformity to type) for series production, ensuring each item conforms to the approved type.

Technical documentation and the EU declaration of conformity

The 10-year retention rule is set by Article 7:

"Manufacturers shall keep the technical documentation referred to in Annex II or Annex III and the EU declaration of conformity for 10 years after the apparatus has been placed on the market."

Article 15 governs the EU declaration of conformity:

"The EU declaration of conformity shall state that the fulfilment of the essential requirements set out in Annex I has been demonstrated."

The DoC must follow the model in Annex IV, contain the elements specified in that Annex, be continuously updated, and be translated into the language(s) required by the Member State where the apparatus is placed or made available. For a deeper dive see declaration of conformity 101 and DoC translation requirements.

CE marking (Articles 16 and 17)

Article 16 — General principles of the CE marking:

"The CE marking shall be subject to the general principles set out in Article 30 of Regulation (EC) No 765/2008."

Article 17 — Rules and conditions for affixing the CE marking:

"The CE marking shall be affixed visibly, legibly and indelibly to the apparatus or to its data plate. Where that is not possible or not warranted on account of the nature of the apparatus, it shall be affixed to the packaging and to the accompanying documents. The CE marking shall be affixed before the apparatus is placed on the market."

For visual placement requirements and proportionality, refer to our CE marking 101.

Information for the user (Article 18)

Often confused with the user-manual requirements of LVD or RED, Article 18 of the EMC Directive specifically requires that the apparatus be accompanied by information on:

• any specific precautions that must be taken when the apparatus is assembled, installed, maintained or used, in order to ensure that, when put into service, the apparatus is in conformity with the essential requirements set out in point 1 of Annex I;
• where applicable, information on the restrictions of use (e.g. when the apparatus is not intended for residential areas).

Information must be in a language easily understood by consumers, other end-users and market surveillance authorities — as determined by the Member State concerned.

Harmonised standards (CISPR, EN 55032, EN 61000 series)

Harmonised standards published in the Official Journal grant a presumption of conformity with the Annex I essential requirements when applied correctly. The Commission maintains a summary list of harmonised standards under Directive 2014/30/EU as PDF and XLS. The principal families are:

Always check the latest OJEU publication — the harmonised standards list is updated several times a year through Commission Implementing Decisions. Using an older edition is a common cause of presumption-of-conformity loss.

Common mistakes

• Citing a withdrawn standard edition. Especially the EN 55032/EN 55035 series and EN 61000-6-x series have rolled through multiple editions. Verify the exact reference, including amendment year (A1, A11), against the current OJEU list.
• Treating a connected radio product under EMC instead of RED. Article 2(2)(a) excludes radio equipment; you must use RED 2014/53/EU. See RED–CRA overlap on connected radio.
• Forgetting Annex IV elements in the DoC. The DoC must explicitly reference Annex I and the harmonised standards applied — not just "complies with EMC Directive".
• Skipping immunity testing. Many manufacturers test emissions and forget Annex I point 1(b) requires adequate immunity. Both halves of the essential requirements must be demonstrated.
• Missing the "information for the user". Article 18 requires specific EMC-related precautions and any residential-use restrictions — separate from the general LVD safety manual.
• Confusing Module A self-declaration with "no documentation needed". Module A still requires the full Annex II technical file, retained for 10 years.

How Cenitia helps

Cenitia drafts your EMC technical file in the exact structure that Annex II of Directive 2014/30/EU expects: general description, schematics, harmonised standards list cross-referenced to the current OJEU citation, immunity and emission test reports, and the EU declaration of conformity per Annex IV. Every claim is grounded in the relevant article — Article 6, Article 7, Article 14, Article 15, Article 17 — with a citation back to EUR-Lex.

When the Commission publishes a new OJEU implementing decision updating EN 55032 or an EN 61000 reference, Cenitia's regulation watcher flags every DoC in your vault that cited the superseded edition, so you can re-issue them before they lose their presumption of conformity.

Frequently asked questions

What does EMC Directive 2014/30/EU cover?

It covers electromagnetic compatibility for equipment placed on the EU market — both apparatus and fixed installations. Per Article 1 and Article 2, it ensures equipment generates limited electromagnetic disturbance and has adequate immunity. Radio equipment falls under the Radio Equipment Directive (RED) 2014/53/EU instead.

Which conformity assessment modules apply under the EMC Directive?

Article 14 of Directive 2014/30/EU permits two routes: Module A (internal production control, Annex II) where the manufacturer self-declares, or Module B+C (EU-type examination by a notified body plus conformity to type, Annex III). Most manufacturers use Module A when harmonised standards are fully applied.

What essential requirements must EMC equipment meet?

Annex I requires that equipment is designed so that (a) the electromagnetic disturbance generated does not exceed a level that prevents radio, telecommunications or other equipment from operating as intended, and (b) it has adequate immunity to the electromagnetic disturbance expected in its intended use. See the verbatim text on EUR-Lex.

Do I need a notified body for EMC compliance?

Not by default. Module A (Annex II) lets the manufacturer self-assess and self-declare. A notified body is only mandatory if the manufacturer chooses Module B+C (Annex III). Many manufacturers consult a notified body voluntarily to gain a second opinion or because a customer or distributor requests it.

How long must EMC technical documentation be retained?

Article 7 of Directive 2014/30/EU requires the manufacturer to keep the technical documentation and the EU declaration of conformity for 10 years after the apparatus has been placed on the market. The same 10-year retention applies to importers (Article 9).

What is the relationship between the EMC Directive and the Radio Equipment Directive (RED)?

Per Article 2(2)(a) of Directive 2014/30/EU, radio equipment is excluded from the EMC Directive because the EMC essential requirements are folded into Article 3.1(b) of RED 2014/53/EU. A connected radio product is assessed under RED, not under 2014/30/EU.
