EMC Testing & Standards

Complete EMC Testing

EMC testing ensures that electronic products comply with regulatory standards for electromagnetic emissions and immunity. Compliance is mandatory for market access and is defined by organisations such as IEC, CISPR, ISO, IEEE, CENELEC, ETSI, FCC, ANSI, RTCA, and MIL-STD committees. As a trusted distributor working with leading EMC suppliers, we help companies align with these standards by providing expert guidance and high-quality testing solutions. These standards are divided into:

Basic Standards– Define test methods (e.g., EN/IEC 61000-4-3 for radiated immunity).

Generic Standards– Set test levels, limits, frequency ranges, and modulation criteria.

Product Standards– Outline test conditions for specific product types.

Manufacturer Standards– Specify unique test levels and conditions.

Internal Company Requirements– Define additional margins and tolerances.

Different industries require adherence to specific EMC standards:

Commercial Electronics:CISPR 11-35, IEC/EN 61000-X-X series

Medical Devices:IEC 60601-1-2, ISO 14708-X

Automotive Systems:CISPR 12, CISPR 25, ISO 11451, ISO 11452

Military & Aerospace:MIL-STD 461, MIL-STD 464, RTCA DO 160

The EMC Testing Process

Pre-compliance Testing

Pre-compliance testing is crucial for identifying and resolving EMC issues early in the design process. It helps improve first-pass compliance rates and reduces costly delays. We support companies by recommending EMC equipment that meets industry standards, ensuring compliance before entering formal testing. Our EMC specialist 'James' works closely with you to select the right tools for your needs and provide expert guidance for the testing process.

Compliance Testing

Compliance testing follows strict protocols and is usually conducted in certified labs using specialised equipment and facilities such as anechoic chambers. It ensures full regulatory approval and market readiness. We help businesses by providing compliant EMC test solutions, ensuring the equipment we suggest aligns with the necessary regulatory requirements and industry standards.

EMC Testing Methods

Electromagnetic Interference (EMI) Testing– Ensures a device does not emit excessive electromagnetic radiation.

Electromagnetic Susceptibility (EMS) Testing– Measures a device’s resistance to external electromagnetic interference.

Key EMC Tests:

Conducted Emissions & Immunity:Analyses unwanted signals through power lines.

Radiated Emissions & Immunity:Measures unwanted radiation from devices and their ability to resist interference.

Additional Tests:Flicker, harmonics, ESD, surge, magnetic field immunity, EFT/burst testing.
