What Is the Certificate?
The Electromagnetic Compatibility Directive (EMC — 2014/30/EU) imposes a two-way requirement: equipment must NOT EMIT electromagnetic interference at a level that would disturb other devices around it (emission), and it must itself be able to operate as expected against interference from the environment (immunity). It is concerned not with the product's safety but with its compatible operation in the electromagnetic environment.
Who Needs It?
- Manufacturers of electrical and electronic equipment
- Manufacturers of industrial control and automation systems
- Manufacturers of IT equipment and power electronics
- Firms installing and integrating fixed installations
- Those importing these products into the EU
Is It Mandatory?
Mandatory for equipment within scope. When the manufacturer fully applies the harmonised standards, it can self-declare through internal production control (Module A); when it does not, or applies them only in part, it must choose the route involving a notified body's opinion (Module B — EU type examination). Radio equipment is outside EMC's scope; its EMC requirements are addressed within RED.
Scope of the Standard
- Scope and definitions: apparatus, fixed installation, electromagnetic disturbance, immunity
- Essential requirements (Annex I): emission limits and the immunity level
- Radiated emission and conducted emission
- Immunity tests: ESD, radiated-field immunity, electrical fast transients (EFT/burst), surge, conducted RF, magnetic field, voltage dips and interruptions
- Specific provisions and documentation for fixed installations
- Conformity-assessment routes: Module A and Module B+C
- The EMC assessment and the content of the technical file
Certification Process
- 1Determining the LegislationIt is determined which EU legislation applies to the product. A product can fall within scope of more than one piece of legislation at the same time; all of them must be met.
- 2Selecting the Conformity Assessment ModuleThe legislation determines the module to follow according to the product's risk class. The manufacturer self-declares under some modules, while a notified body is involved under others.
- 3Testing Against Harmonised StandardsConformity with harmonised standards published in the EU Official Journal is demonstrated through testing; this provides a presumption of conformity with the legislation.
- 4Risk Analysis and the Technical FileThe risk assessment, design calculations, test reports, instructions for use and sample labels are compiled in the technical file.
- 5The EU Declaration of ConformityThe manufacturer or its EU-based authorised representative signs the declaration of conformity. Responsibility rests with the signatory of the declaration.
- 6Affixing the CE MarkThe mark is affixed to the product in the form and size the legislation prescribes; the notified body's identification number is added if one is involved.
- 7Retaining the Technical FileThe technical file is retained for the period the legislation sets from the product's placing on the market (10 years under most legislation) and presented to the competent authority on request.
Period of Validity
The CE mark is not a certificate but the manufacturer's declaration of conformity, and it has no expiry. However, the declaration remains valid as long as the product and the legislation do not change: the technical file must be updated if the legislation or the harmonised standard is updated. Notified-body certificates (e.g. an EU Type-Examination Certificate) are subject to a validity period.
Required Documents
- The product description, model list and technical drawings
- Risk assessment
- The list of harmonised standards applied
- Test reports
- Instructions for use and warning labels (in the target market's language)
- A draft EU Declaration of Conformity
- The product's block diagram, wiring and earthing arrangement
- Critical-component and filter information
- The list of harmonised standards applied (e.g. EN 55032, EN 55035, the EN IEC 61000-6 series)
- Emission and immunity test reports
- The product's operating mode during testing and the definition of the performance criterion
Certification Cost
There is no fixed list price; the cost is calculated based on the following variables and provided in writing in the quote.
- The number of pieces of legislation applicable to the product
- The conformity-assessment module — whether a notified body is involved
- The required test scope and number of samples
- The current state of the technical file
- Translation and documentation needs
Accreditation
A Notified Body under CE is registered in the European Commission's NANDO database for the relevant EU regulation and carries a four-digit identification number. Notified body authority is based on legislation and product scope; The authority granted for one regulation does not extend to another. Testing is within the scope of ISO/IEC 17025, product certification is within the scope of ISO/IEC 17065.
The scope under which this scheme can be offered varies according to your product and activity; it is confirmed in writing at the quote stage.

Frequently Asked Questions
Can I have EMC and LVD tests done at the same time?
Yes, laboratories usually schedule these two together. Both pieces of legislation must be met separately, and both must be listed in the declaration of conformity.
My product contains a radio module — does the EMC Directive or RED apply?
RED (2014/53/EU) applies to radio equipment. Because RED incorporates EMC and safety requirements into its own essential requirements, the EMC Directive does not additionally apply. Using an approved module does not remove the need for the final product to be tested.
In the immunity test, must the product be completely unaffected?
No. The standards define a performance criterion: temporary degradation followed by self-recovery is acceptable in some tests. The manufacturer defines what acceptable behaviour is before the test, and this definition is written into the report.
Who affixes the CE mark?
The manufacturer, or its EU-based authorised representative. A certification body does not affix the CE mark; it only takes part in conformity assessment as a notified body where the legislation requires it, and issues its own certificate. Responsibility for the declaration always rests with the manufacturer.
Is the CE mark a quality certificate?
No. CE is a declaration that the product meets the health, safety and environmental requirements of the relevant EU legislation; it does not show a level of quality or superior performance.
How long do I need to keep the technical file?
For most EU legislation, 10 years from the product's placing on the market. Since the period can vary by legislation, it must be confirmed from the relevant article of the applicable regulation. The file is presented to the market-surveillance authority on request.
