EMC Testing Standards for CE Marking: Which Ones Apply

Which EMC testing standards apply to your product? Start with its function and intended environment, then check power supplies, connected ports and any radio features. Product-specific or product-family standards usually come before generic standards.

Quick answer: EMC compliance is mandatory for equipment within scope; using harmonised standards is voluntary. A cited harmonised standard can provide a presumption of conformity only for the requirements it covers, subject to the applicable Official Journal reference and restrictions.

EMC standards describe emissions limits, immunity requirements or test methods. They help you establish how a product behaves around other electrical equipment. Passing an EMC test alone does not complete every requirement for CE marking.

This guide covers standard selection, practical product examples and what to prepare before booking a laboratory. For the wider process, see our EMC Directive compliance guide.

When Do You Need EMC Testing for CE Marking?

First establish which legislation covers the finished product. Electrical and electronic apparatus within the EMC Directive's scope must satisfy its emissions and immunity requirements. An EMC assessment determines the evidence and testing needed; battery operation alone is not an exemption.

Typical assessment candidates include consumer electronics, industrial controls, lighting and power supplies. Scope exclusions and special cases still need checking. Radio equipment, including many Wi-Fi and Bluetooth products, is assessed under the Radio Equipment Directive rather than the EMC Directive for its EMC requirements.

Use the European Commission's EMC guidance to establish the applicable route before selecting tests.

Types of EMC Standards

EMC standards fall into three main categories.

Basic Standards

These describe how to perform specific EMC tests (e.g., electrostatic discharge, surge immunity). They are rarely used alone.

Generic Standards

Used when no dedicated product-family standard exists. They are based on the intended environment:

• Residential
• Industrial
• Commercial

Product (Family) Standards

These take priority. They apply to defined product categories and environments. Examples include:

• EN 55032: multimedia equipment emissions
• EN 55035: multimedia equipment immunity

Emissions vs Immunity: What’s the Difference?

EMC compliance is divided into two technical pillars:

Emissions Testing

Measures the electromagnetic energy your product releases into its surroundings. Excess emissions can interfere with nearby equipment.

Examples:
• Radiated emissions
• Conducted emissions

Immunity Testing

Assesses how well your product continues to operate when exposed to electromagnetic disturbances.

Examples:
• Electrostatic discharge (ESD)
• Surge immunity
• RF field immunity

Both are required under the EMC Directive.

For common failure patterns and how engineers resolve them, see Common EMC Test Failures and How to Fix Them.

How Do You Know Which EMC Standard Applies?

Selecting the correct EMC standard depends on:

1. Product category
2. Intended use environment
3. Functional characteristics

The hierarchy is:

1️⃣ Product standard (if available)
2️⃣ Generic standard
3️⃣ Basic standards supporting test methods

A report against an unsuitable standard may leave relevant requirements unassessed. Record why each selected standard covers your product and intended use.

Choosing the right standard is closely linked to choosing the right lab, explained in How to Choose an EMC Testing Lab.

EMC standards reference table: which standard covers which product

Use these references as starting points, not a universal test specification. Check the scope, dated EN edition, amendments and current Official Journal citation before commissioning tests. The Commission's EMC standards page links to the relevant decisions. Its summary also includes withdrawn references and is informational; a newer IEC edition is not automatically a harmonised EN edition.

Product-family standards (use these first)

Generic and mains-connection standards

Use the generic standards only when no product-family standard fits. Check whether additional EN 61000-3 harmonic-current or flicker requirements apply to the product's mains connection, rated current and the scope of the relevant standard.

Basic standards (test methods)

Basic standards define how a test is run. They are not cited on their own in the Commission's list; product-family and generic standards call them up and set the test levels.

Radio products are different. Anything with Wi-Fi, Bluetooth, cellular or another radio function falls under the Radio Equipment Directive 2014/53/EU, not the EMC Directive, and its EMC requirements are normally shown with the ETSI EN 301 489 series.

Scope of this table: it covers common electronics categories. It does not cover medical devices, automotive, railway, marine or sector-specific machinery standards, which the Commission's list also includes.

Which EMC standards apply to common product types?

These examples help you brief a laboratory. They do not replace checking the exact standard scope and current cited edition for your finished product.

Multimedia equipment: do I need EN 55032 and EN 55035?

For non-radio multimedia equipment within their scope, EN 55032 addresses emissions and EN 55035 addresses immunity. A monitor or audio device may therefore need both parts of the assessment. Confirm the intended environment, emissions class, cables and connected peripherals. The CISPR 32 scope explains the underlying multimedia emissions category; EU citation status must be checked separately.

Industrial instruments: EN 61326-1 or generic EN 61000-6 standards?

For measurement, control and laboratory equipment, check EN 61326-1 and any applicable particular requirements first. Selling a product for industrial use does not automatically make generic industrial standards the right choice. Describe the instrument's function, installation environment and measurement performance to the lab. See the IEC 61326-1 scope for the equipment category.

Wi-Fi or Bluetooth products: does an EMC report cover the radio requirements?

No. Radio equipment has a separate assessment under the Radio Equipment Directive, including EMC requirements. The relevant ETSI EN 301 489 parts may form part of that assessment. Identify the radio technologies and final product configuration before agreeing a test plan; a module report alone should not be treated as proof that the finished product meets every applicable requirement.

Battery-powered products: can I skip EMC testing?

Battery power does not establish an EMC exemption. Tell the lab whether the device operates while charging, which external cables it uses and what accessories are supplied. Those configurations can change the relevant assessment. A device used without a mains connection will not have the same mains-port test scope as a mains-powered product.

Is EMC testing mandatory for CE marking?

EMC conformity is mandatory for apparatus within scope, but the EMC Directive does not impose a universal third-party laboratory certificate. Manufacturers must assess conformity and retain adequate supporting evidence. Harmonised standards are voluntary; alternative technical solutions need a documented justification.

Internal production control is an available conformity assessment route under the EMC Directive. This does not mean declaring compliance without an assessment. Agree which tests, calculations and existing evidence support your product. Other applicable legislation may impose different procedures.

How should I prepare my product for EMC testing?

Use this practical checklist with your chosen lab before dispatching samples. The lab should confirm the setup and test programme for your specific product.

1. Define the product and variants. Send the model list, intended use, target environment and differences between variants. Agree which samples represent the range.
2. Record the tested build. Identify hardware and firmware versions, enclosure, shielding and key components. Log any modifications made during testing.
3. Supply a complete operating setup. Include the intended power supply, chargers, cables, peripherals, loads and fixtures. Explain installation and grounding arrangements.
4. Make operating modes reproducible. Provide instructions or test software for sustained operation. Agree representative worst-case modes, such as active data transfer or maximum load, where relevant.
5. Define immunity performance. Tell the lab which functions must be monitored and how faults are detected. Agree the performance criteria required by the selected standard before testing begins.
6. Confirm logistics and support. Agree sample quantity, dimensions, power needs, access credentials and an engineer who can answer questions. Include safe operating instructions.
7. Agree report and retest scope. Confirm exact standards and editions, ports and modes covered, exclusions, report deliverables and how failures or design changes will be handled.

Before you book: ask the laboratory to return a written test plan. It should connect your product configuration to the selected standards and explain any tests excluded from scope.

For large equipment tested on site, preparation also includes access, space and operating conditions; see Intertek's in-situ preparation guidance. For design troubleshooting, use our EMC failure and fixes guide.

EMC Standards and Your Technical File

EMC test evidence must be included in your CE Technical Documentation, including:

• Test reports
• Standard references and versions
• Test setup configuration
• Product variants covered
• Deviations and justifications

Keeping this documentation organised and version-controlled is critical. Many manufacturers use structured compliance workflows (like EcoComply) to track evidence and detect documentation gaps before market surveillance requests.
