EMC Directive 2014/30/EU: Electromagnetic Compatibility for Industrial Equipment and CE Marking.

The EMC Directive 2014/30/EU applies to electrical and electronic equipment (apparatus) that can cause electromagnetic disturbance or whose performance can be affected by such disturbance. It covers a very wide range of products: from industrial machinery and drives to household appliances, IT equipment, and professional radio equipment. The Directive does not apply to: radio equipment covered by RED 2014/53/EU, aeronautical equipment, radioactive material, implantable medical devices, large fixed installations (but components used in them must still comply if sold separately), equipment specifically designed for military or classified purposes, and equipment designed for research use in laboratories.

Article 3 of the EMC Directive excludes fixed installations from CE marking requirements. A fixed installation is defined as a particular combination of several types of apparatus and, where applicable, other devices, which are assembled, installed and intended to be used permanently at a predefined location. The exclusion conditions are: (1) the installation must conform to good engineering practices and respect the relevant essential requirements, (2) a competent person must assess conformity, (3) documentation identifying the installation and the competent person’s details must be held by the responsible person and made available to market surveillance authorities. Individual components used in the installation must still bear CE marking if they are placed on market as separate products.

Several harmonised standards cover industrial equipment under EMC 2014/30/EU. Product-specific standards (type A) take precedence: EN 55011 / CISPR 11 for industrial, scientific and medical equipment; EN 61800-3 for adjustable speed drives; EN 62477 for power electronics. Generic standards (type C) apply when no product-specific standard exists: EN 61000-6-4 for emissions in industrial environments, EN 61000-6-2 for immunity in industrial environments. Generic residential standards (EN 61000-6-3 and EN 61000-6-1) apply for equipment intended for residential use. Always check the Official Journal for the latest published harmonised standards and their applicability dates.

Under EMC 2014/30/EU, a Notified Body opinion (Annex III) is only required in specific circumstances: when the manufacturer chooses not to apply any published harmonised standard, or when the manufacturer applies harmonised standards only partially. In these cases, the manufacturer must submit the technical file to an EMC Notified Body, which issues a technical opinion. If the manufacturer applies published harmonised standards in full, no Notified Body involvement is needed — internal control (Annex II) is sufficient. Note that Notified Bodies under EMC Directive do not issue certificates — they issue opinions. The manufacturer retains responsibility for the CE marking.

The EMC technical file must enable conformity assessment and must include: (a) a general description of the apparatus and its intended use, (b) design and manufacturing information: drawings, diagrams, component lists, (c) references to harmonised standards applied or, if not applied, descriptions of solutions to meet the essential requirements, (d) results of design calculations, examinations or tests carried out, including EMC test reports with test setup, configuration, frequencies measured, limits and results, (e) a statement that the apparatus conforms to the essential requirements of EMC 2014/30/EU when placed on the market. Test reports must include sufficient detail to allow the test to be reproduced — this includes equipment configuration, cable arrangement, and test layout photographs.

Many products must comply with multiple CE marking directives simultaneously. Industrial machinery typically needs both the Machinery Directive 2006/42/EC (or Machinery Regulation 2023/1230 from 2027) and EMC 2014/30/EU. Electrical equipment in the LVD voltage range needs both LVD 2014/35/EU and EMC 2014/30/EU. Radio equipment falls under RED 2014/53/EU which covers both EMC and radio spectrum requirements — not the separate EMC Directive. When multiple directives apply, a single CE marking and a single DoC (listing all applicable directives) can be used. The technical file must demonstrate compliance with all applicable directives.
