As electrical and electronic products become more connected, compact, and digitally sophisticated, electromagnetic compatibility (EMC) is becoming an increasingly important part of product development. Manufacturers need to understand EMC Regulations to ensure that their equipment does not create unacceptable electromagnetic interference and can continue operating correctly when exposed to electromagnetic disturbances.
For businesses planning product launches or compliance testing during 2026 and 2027, the regulatory landscape deserves close attention. However, it is important to distinguish confirmed regulatory changes from proposed standards work and industry expectations.
The EU continues to operate under EMC Directive 2014/30/EU, while new amendments and ongoing harmonised-standard development are shaping how manufacturers should approach future compliance.
What Is Changing for EMC in 2026-2027?
There is not one single worldwide “new EMC regulation” taking effect in 2026 or 2027. Requirements depend on the market, product type, technology, and applicable legislation.
For the European Union, one confirmed development is Directive (EU) 2024/2749, which amended several product directives, including the EMC Directive, to introduce emergency procedures connected with an internal-market emergency. The amendments were required to be transposed by 29 May 2026 and apply from 30 May 2026.
These provisions are primarily designed for exceptional emergency situations rather than creating a completely new everyday EMC testing regime.
At the same time, the European Commission is working with European standardisation organisations on updating the harmonised standards supporting the EMC Directive.
Key areas manufacturers should watch include:
- Radiated and conducted emissions
- Electromagnetic immunity
- Electrostatic discharge (ESD)
- Electrical fast transient/burst testing
- Surge testing
- Voltage dips and interruptions
- Harmonics and flicker
- Measurement uncertainty
- Test configurations and methods
- Documentation and conformity assessment
- Installation and earthing considerations
The Commission’s 2026 standardisation work specifically identifies these areas for revision and development of harmonised European EMC standards.
Why Harmonised Standards Matter
A major point manufacturer should understand is the difference between legislation and standards.
The EMC Directive establishes the legal requirements. Harmonised standards provide technical methods that manufacturers can use to demonstrate conformity with those requirements.
The European Commission explains that references to harmonised standards need to be published in the Official Journal of the European Union (OJEU) to provide the relevant presumption of conformity.
This means manufacturers should not assume that simply using the newest technical standard automatically provides legal compliance. The status and publication of the applicable standard need to be checked for the relevant product and market.
For manufacturers, this means:
- Review applicable standards regularly.
- Check whether a standard has been newly published or withdrawn.
- Confirm its OJEU status where EU conformity relies on harmonised standards.
- Review existing test reports when applicable standards change.
- Maintain technical documentation.
- Plan compliance testing before product launch.
What Does This Mean for EMC Testing?
EMC testing is likely to remain an important part of product development throughout 2026 and 2027.
A typical EMC evaluation may involve both emissions and immunity testing. Emissions testing determines whether a device produces electromagnetic disturbances above applicable limits, while immunity testing evaluates whether the device continues to operate correctly when exposed to specified disturbances.
The exact tests depend on the product category and applicable standards.
For example, an electronic product may require assessment of:
| EMC Area | What It Evaluates |
|---|---|
| Conducted emissions | Noise travelling through power or signal cables |
| Radiated emissions | Electromagnetic energy emitted into the surrounding environment |
| ESD immunity | Response to electrostatic discharge |
| EFT/burst | Response to fast electrical transients |
| Surge immunity | Response to high-energy transient disturbances |
| Radiated immunity | Performance when exposed to electromagnetic fields |
| Conducted immunity | Response to disturbances entering through cables |
| Voltage dips/interruptions | Behaviour during power-quality disturbances |
Testing should be selected according to the product’s applicable standards rather than using a generic EMC test package.
What Manufacturers Should Do Now
Companies preparing products for European or international markets should treat regulatory monitoring as an ongoing activity rather than a one-time compliance exercise.
First, identify the markets.
Determine where the product will be sold and which legislation applies.
Second, identify the applicable product standards.
The correct EMC requirements depend heavily on the product category, technology and intended environment.
Third, review existing compliance evidence.
Older reports may need to be reassessed if applicable standards or test conditions change.
Fourth, build EMC testing into product development.
Waiting until the final production stage can make EMC failures expensive to correct.
Finally, monitor official updates.
The European Commission’s harmonised-standard publications and OJEU references should be checked rather than relying solely on informal regulatory summaries.
What About the UK?
The UK maintains its own product-regulatory framework. For Great Britain, the current legislation for electromagnetic compatibility remains the Electromagnetic Compatibility Regulations 2016.
The UK Government’s 2026 product-regulations guidance confirms that businesses can use UKCA or CE marking under the applicable arrangements for placing products on the Great Britain market.
Therefore, manufacturers supplying both EU and UK markets should not automatically assume that one compliance strategy covers every regulatory obligation.
The applicable legislation, marking requirements, designated or harmonised standards, and conformity-assessment route should be checked for each market.
How EMC Testing Facilities Can Help
For manufacturers, a controlled testing environment can help identify electromagnetic compatibility problems before products reach the market.
Diamond Microwave Chambers Ltd provides specialist chamber solutions for controlled electromagnetic testing environments. Properly designed EMC test facilities can help reduce unwanted external interference and provide the controlled conditions required for repeatable measurements.
A well-planned test environment is particularly important when manufacturers need reliable measurements during product development, troubleshooting, verification and compliance testing.
Pro Tip
Pro Tip: Don’t wait for a regulation to become mandatory before reviewing your EMC test strategy. Track applicable standards early, perform pre-compliance testing during development, and keep your technical documentation aligned with the standards used for final conformity assessment.
Looking Ahead to 2027
The most important EMC development for manufacturers may not be a single new regulation with a universal 2027 deadline. Instead, businesses should watch the continuing evolution of harmonised standards, technical test methods and conformity-assessment requirements.
The European Commission’s standardisation request indicates work toward updated EMC standards covering emissions, immunity, measurement uncertainty, test setups, documentation and related technical considerations.
For this reason, manufacturers should treat 2026-2027 as a period for regulatory vigilance and proactive compliance planning.
Keeping product designs, test procedures, technical documentation and laboratory capabilities aligned with the latest applicable requirements can help businesses reduce compliance surprises and support smoother market access.
Diamond Microwave Chambers Ltd can support organisations looking for controlled electromagnetic testing environments as they prepare for evolving EMC testing requirements.
Important: EMC requirements vary by jurisdiction and product. This article is an informational regulatory watch, not legal or conformity-assessment advice. Always verify the current legislation, applicable standards and official OJEU/designated-standard status for your specific product and target market.
Frequently Asked Questions
Not one single global EMC regulation. The EU continues to use EMC Directive 2014/30/EU, while amendments and ongoing harmonised-standard revisions are important developments manufacturers should monitor.
Directive (EU) 2024/2749 introduced emergency-related conformity-assessment provisions into several product directives, including the EMC Directive. These provisions apply from 30 May 2026 after the required national transposition.
Specific testing requirements depend on the applicable product standards and their regulatory status. European standardisation work is addressing areas including emissions, immunity, ESD, EFT, surge, voltage disturbances and measurement uncertainty.
They may remain useful, but manufacturers should review them whenever applicable standards, product designs, intended markets or conformity requirements change. The current status of relevant standards should always be verified.
No. Great Britain has its own Electromagnetic Compatibility Regulations 2016, although CE marking continues to be recognised under current UK arrangements. Manufacturers should verify the requirements for each market.
