Importance of EMC Testing
Electromagnetic Compatibility (EMC) ensures that electronic devices operate reliably — without causing interference to other systems and without being affected by external electromagnetic disturbances.
Our ISO/IEC 17025–accredited EMC testing covers all relevant disciplines, from Electromagnetic Susceptibility (EMS) to Electromagnetic Interference (EMI), providing the basis for global market approval under CE, FCC, ISED, UN ECE R10, and other regulatory frameworks.
Immunity Testing
EMS / Electromagnetic Susceptibility
- Radiated immunity (EN 61000-4-3)
- Conducted immunity (EN 61000-4-6)
- Transient immunity: ESD, Burst, Surge (EN 61000-4-2/4/5)
Emission Testing
EMI / Electromagnetic Interference
- Radiated emissions (CISPR 32)
- Conducted emissions (CISPR 32)
Power Quality
Mains Harmonics & Voltage Fluctuations
- Harmonics (EN 61000-3-2)

Frequently Asked Questions
All you need to know about EMC testing
- What does EMC means?
-
Electromagnetic Compatibility (EMC) refers to the ability of an electrical or electronic device to operate as intended within its electromagnetic environment — without causing interference to other equipment and without being affected by external electromagnetic sources.
A product is considered electromagnetically compatible when it emits no excessive interference (EMI – Electromagnetic Interference) and is sufficiently resistant to external disturbances (EMS – Electromagnetic Susceptibility). - What do EMI and EMS stand for?
-
EMI (Electromagnetic Interference) describes unwanted electromagnetic emissions that can disrupt the operation of nearby equipment.
EMS (Electromagnetic Susceptibility) defines a device’s ability to maintain reliable operation when exposed to such disturbances.
Both are key performance parameters in EMC testing.
- Is EMC testing mandatory?
-
Yes. EMC testing is required for placing products on the EU market and forms an integral part of the CE marking process. Compliance is demonstrated through technical documentation and the EU Declaration of Conformity (DoC), confirming that the product meets all applicable directives.
- Which EMC standard applies to my product?
-
This depends on the product category, operating environment, and radio functionality — for example, EN 55032 / EN 55035 for multimedia devices, EN 61000-6-x for generic environments, or ETSI EN 301 489-xx for radio equipment.
Further details are available in the EMC Standards & Regulations section of this page.
- Do you offer pre-compliance testing during development?
-
Yes. IB-Lenhardt AG offers pre-compliance testing in 3 m / 5 m chambers to accelerate design iterations and minimize certification risks.
These tests are part of our development-support services — see the Pre-Compliance section for more information.
