Electromagnetic Compatibility (EMC) Tests
Electromagnetic Compatibility (EMC) testing ensures that vehicles and components operate correctly within their electromagnetic environment, meeting emissions and immunity requirements (radiated and conducted).
CSI provides end-to-end EMC testing services for the automotive industry, supporting type approval, certification, and product development.
EMC testing objectives
In the automotive sector, EMC tests ensure:
- Immunity to electromagnetic disturbances for safety-critical systems and vehicle control functions
- Control of unwanted electromagnetic emissions, preventing interference with onboard and nearby devices
- Compliance of electric charging systems, especially at the vehicle-to-grid interface
Regulations and standards
- UNECE Regulation R10 - Homologation tests for vehicles, systems, and components, including:
- electrical transients
- voltage dips on power and signal lines
- International standards (ISO, SAE) and OEM specifications - Testing under real and abnormal operating conditions.
Electromagnetic Emissions Testing
EMC emissions testing verifies compliance with regulatory limits for electromagnetic interference.
Available services:
- Radiated emissions in a 10-meter semi-anechoic chamber
For electric and hybrid vehicles:
- Conducted emissions
- Mains harmonics measurements
- Flicker testing (voltage fluctuations)
Electromagnetic Immunity Testing
Immunity testing evaluates the ability of systems to operate reliably under electromagnetic disturbances.
Testing scope:
For electric and hybrid vehicles:
- Conducted immunity
- Electrical fast transient (Burst) tests
- Surge immunity tests
- Voltage dips and interruptions
- Electrostatic discharge (ESD) tests
