Understanding the Latest Changes to EMC Compliance Standards and Their Effect on Exporters (Updated January 2026)

2nd March 2026

As global regulatory regimes evolve, electronics manufacturers and exporters must stay ahead of electronics compliance requirements — especially in electromagnetic compatibility (EMC). Since mid-2025, key developments in CE and UKCA marking requirements for exporters, and associated EMC standards have reshaped the landscape for product conformity.

This updated guide explains what these changes mean in practice, how EMC testing and compliance fit alongside RoHS and REACH requirements, and how manufacturers can avoid certification delays as they bring products to market in both the United Kingdom and the European Union. [Update of earlier article on EMC Testing and Compliance Standards]

Why EMC Compliance Still Matters for Electronics Exporters

EMC (Electromagnetic Compatibility) ensures that an electronic product:

Does not emit electromagnetic interference (EMI) above acceptable levels

Is resilient to electromagnetic disturbances in its intended environment

Both CE and UKCA conformity frameworks require EMC compliance before a product can be legally placed on the market.

EMC testing is often one of the most challenging parts of compliance for electronic products — and is consistently one of the leading causes of product redesigns and certification delays.

UKCA vs CE: Updated Regulatory Landscape

CE Marking — Still Mandatory for EU/EEA Markets

CE marking confirms that a product complies with all applicable European directives:

EMC Directive

Low Voltage Directive

RoHS Directive

REACH requirements

Radio Equipment Directive (if applicable)

Manufacturers must produce a Technical File, conduct required testing, and issue a Declaration of Conformity before affixing a CE mark.

UKCA Marking — Current Status for Great Britain

Since Brexit, UKCA marking has gradually replaced CE marking for products sold in:

England

Scotland

Wales

However, recent UK government updates have extended indefinite recognition of CE marking in many cases, meaning CE-marked products may still be marketed in Great Britain without immediate UKCA retesting.

This does not apply universally — products requiring third-party conformity assessment or approvals by a Notified/Approved Body may still require a UKCA route.

The key take-aways:

✔ CE marking continues to be accepted for many products in GB

✔ UKCA marking is required for certain regulated goods now or in the near future

✔ Dual CE and UKCA strategy often gives maximum market flexibility

EMC Standards: What Changed and How It Affects Testing

EMC standards evolve periodically to reflect new technology, test methodologies, and field performance expectations.

Notable Standards Updates

Recent revisions include:

EN IEC 61000-4-2:2025 — Updated electrostatic discharge (ESD) immunity testing

EN IEC 61000-4-3:2020 — RF immunity changes

EN IEC 61000-4-41:2025 — New test methods for certain device categories

EN IEC 61000-3-2:2019/A2:2024 — Harmonic emissions updates

These standards form the basis of EMC conformity testing under both EU and UK regulations. Simply listing revised standards is not enough — manufacturers must understand implementation timelines.

Effective vs Mandatory Dates

Many updated standards have effective dates that differ from mandatory conformity dates. For example:

A new standard may be published in 2025

But previously harmonised versions remain acceptable until later phase-out dates (often 2027–2028)

This means:

Manufacturers can typically choose earlier standards as long as they produce acceptable test evidence

However, planning for future versions reduces the risk of late re-testing

Clear documentation in the Technical File is key to demonstrating conformity during regulatory reviews.

From Design to Compliance: A Risk-Based Approach

Regulatory authorities and guidance documents (e.g., the EU Blue Guide) emphasise that compliance should be based on risk assessment, not just checklist testing.

Key risk-based practices include:

Worst-Case Analysis: Evaluating the most demanding EMC scenarios for the product

Component Evaluation: Understanding how components contribute to EMI emission or susceptibility

Early Simulation: Using predictive tools before physical testing reduces costly redesign cycles

Environment Assessment: Planning tests based on intended product environments (industrial, medical, consumer)

Treating compliance as a design discipline, rather than a certification hurdle, significantly improves outcomes.

RoHS and REACH: Complementary Chemical Compliance

EMC is only one part of the compliance picture.

RoHS Compliance

RoHS restricts hazardous substances in electronics, including lead, cadmium and certain flame retardants. Demonstrating RoHS conformity requires:

Supplier material declarations

Traceability documentation

Test evidence for restricted substances

REACH Compliance

REACH focuses on the safe use of chemicals, particularly Substances of Very High Concern (SVHCs). REACH documentation is often required alongside EMC and RoHS evidence in Technical Files.

While RoHS and REACH do not directly affect EMC performance, regulators expect full conformity across all applicable product legislation.

Common Challenges and Mistakes in EMC Compliance

Manufacturers often encounter compliance issues because:

✔ EMC is treated as a late-stage check

✔ Test labs are selected without considering applicable harmonised standards

✔ Documentation lacks sufficient traceability

✔ Regulatory updates are not continuously monitored

Proactive compliance planning reduces risk and provides greater confidence in market access.

Practical Guidance for EMC Test Planning

When preparing for EMC testing, consider:

Test Lab Selection - Choose labs with accreditation for your product’s scope

Pre-Compliance Testing - Early testing identifies potential failures before formal certification

Documentation Discipline - Maintain records of standards versions, test results, and Technical File components

Continual Update Practices - Standards and regulations change — integrate tools to track revisions

These behaviours minimise delays and reduce redesign costs.

In short, we help clients turn compliance from a regulatory burden into a quality differentiator.

Conclusion

Understanding the latest changes to EMC testing and compliance standards — and how they interact with UKCA and CE requirements — is essential for electronics exporters.

By integrating risk-based planning, continuous standards monitoring, and robust documentation practices, manufacturers can confidently place products in global markets.

Regulatory compliance is not static — but when approached strategically, it becomes a competitive advantage rather than a barrier.
