The EMC Directive applies to all electrical and electronic products capable of generating or being affected by electromagnetic interference. It directly involves those who design, manufacture, import or distribute such equipment within the European market. It also applies to systems integrators who combine and assemble components to build machinery – such as electrical cabinets, machine-side wiring, operator control panels, motors with inverters and related acutators.
EMC Directive
Full EMC Compliance: testing, analysis and technical documentation to ensure safety and regulatory conformity
What is the EMC Directive?
The Electromagnetic Compatibility (EMC) Directive applies to all equipment containing electrical and electronic circuits. This is because such circuits can emit electromagnetic disturbances during operation or may be sensitive to interference from surrounding systems. The Directive also extends to fixed plants and installations that incorporate such equipment or components, including those installed on machinery. Compliance with this Directive mandates the application of the CE Marking to the product.
Equipment is presumed to comply with the Directive if its emission levels do not interfere with the normal operation of radio and telecommunications devices.
Furthermore, it must demonstrate, under its intended conditions of use, an adequate level of immunity to external electromagnetic interference, ensuring it functions correctly without significant performance degradation.
To demonstrate compliance, products must undergo testing according to applicable international standards. The test results, along with the supporting technical documentation, from the basis for the Technical File and the subsequent application of the CE mark.
EMC Directive 2014/30/EU
EMC: a mandatory requirement for anyone placing electronic devices on the market
Mandatory Compliance
Whether dealing with a simple device or complex machinery, anyone placing electrical and electronic equipment on the market – be they manufacturers, importers or distributors – is required to guarantee compliance with the EMC Directive. This responsibility extends across the entire supply chain, from production to distribution, to ensure a safe and compatible electromagnetic environment.
Industries we serve
Laboratory and in-situ EMC testing to ensure tailored electromagnetic compliance across multiple sectors
A clear workflow to achieve CE compliance
We perform EMC testing on industrial plants, production lines and industrial machinery. We support manufacturers and designers of electrical and electronic equipment throughout the optimization and fine-tuning of their products.
Initial Analysis
We perform an in-depth analysis of the device under test to define its individual components and develop an EMC block diagram. This analysis is essential for identifying the specific technical characteristics of your equipment that impact electromagnetic compatibility.
Regulatory classification of the device under test
Classification of the device under test according to harmonized technical standards under the EMC Directive. This process involves evaluating specific requirement, scopes of application and the appropriate testing methodologies.
Definition of testing activities
Definition of the testing activities to be performed based on the device’s electrical currents and our laboratory instrumentation. This process takes into account operating frequencies, emission modes, required immunity thresholds and the specific environmental test conditions requested.
Laboratory or in-situ testing
Collaborating with the client to determine the most suitable testing location: either at our laboratory or in-situ (at the client’s premises)
Test execution and issuance of the test report
During this phase, emission and immunity tests are performed in accordance with the applicable harmonized standards. The results are documented in detail with the test report, which includes test configurations, instrumentation used, environmental conditions and compliance with regulatory limits
Test report and corrective actions
Should any critical issues arise during the testing phase, further in-depth investigations into specific tests can be conducted. This involves a detailed analysis of the root causes of any anomalies, verifying test configurations, comparing results against regulatory limits and proposing effective corrective solutions.
EU Market access
CE marking under the EMC Directive grants you the right to freely market and distribute your products throughout the European Union.
Regulatory compliance
It ensures your devices meet stringent European requirements for both electromagnetic emissions and immunity
End-User protection
It prevents malfunctions caused by interference, safeguarding both user safety and the overall user experience
Risk mitigation & reliability
It reduces the likelihood of failures caused by electromagnetic interference, significantly increasing the long-term reliability of your product.

FAQ
Is EMC Directive compliance mandatory for industrial machinery? Is the Machinery Directive alone sufficient?
Any machinery containing electrical or electronic components is subject to te requirements of the EMC Directive, To put it simply: only machinery entirely devoid of electrical parts is exempt from EMC obligations.
When can my machinery be classified as a "fixed installation"?
Fixed installations are 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. This definition is established in the Official Guide to the EMC Directive
https://ec.europa.eu/docsroom/documents/33601
Examples of fixed installations include: electric power stations, telecommunication networks, radio and TV networks, airport runway lighting and wind farms. Please refer to the guide for further details.
If i have a fixed installation, does that mean i don't need to perform tests?
Achieving EMC Directive compliance for fixed installations involves developing a tailored testing strategy. Despite their complexity, fixed installations are still required to satisfy fundamental emission and immunity standards.
What do EMC tests actually involve?
Emission tests are performed to verify that any disturbance generated by the device remain below the limits set by the standards. Simultaneously, immunity tests are carried out to ensure the equipment continue to function correctly within the electromagnetic environment in which it is installed.
Are EMC tests destructive?
Some immunity tests involve generating pulses that could potentially damage the equipment; however, thee pulses are typical of what is found in real-world electrical networks. For this reason, performing these tests is essential to prevent costly failures or malfunctions once products have already been deployed in the field.
What does in-situ testing involve?
In-situ electromagnetic compatibility testing is conducted using procedures that mirror laboratory conditions as closely as possible. Any deviations from the standard, necessitated by the specific environmental conditions of the site, are carefully documented and accounted for.
Can in-situ testing be performed on any product?
When machinery is too large to be transported to a laboratory, testing can be organized at the installation site. However, planning this activity requires specific precautions and technical considerations.
How can i determine if my device falls under the residential or industrial class?
It is the manufacturer’s responsibility to define the most appropriate electromagnetic environment based on the installation characteristics and the intended market for the product. Since regulatory limits vary depending on the type of environment, defining this correctly is essential to ensure the so-called compatibility margin.
I have cited the EMC Directive 2014/30/UE in my CE Declaration of Conformity. What are the implications?
By doing so, you are formally declaring that your product complies with the Directive – and consequently with its essential requirements, including all relevant emission and immunity testing. This declaration carries significant legal liability for the manufacturer. Regulatory authorities have the power to request formal evidence demonstrating that the product truly conforms to the claims made in your declaration.
