Automotive EMC Testing

Vehicle Component EMC Testing

Component EMC testing is critically important. Trust the experts with the expertise and credentials to get the job done on your schedule.

Component Level EMC Compliance Sets the Stage for Safe and Reliable Vehicle Operation

Car, truck, and commercial vehicle manufactures perform EMC testing on their whole vehicles as a final system verification and before their products can be placed on the market.  Emissions measurements confirm vehicle radios, communications, and navigation equipment are not degraded by the RF noise from electronic subsystems.  High intensity RF fields and ESD (discharge) are directed at the whole vehicle to verify passenger safety and for the protection of other road users.

Component level EMC is critically important because modern vehicles have dozens of microprocessor based modules, a multitude of sensors, communications equipment, and motors.  In addition, whole vehicle EMC testing takes place late in the production process, and when nearly all Electronic Sub-Assemblies (ESAs) and components are designed and on their way to production.  This means compliance of each individual component on the vehicle must be separately assured, and well in advance of the final vehicle testing.

EMC testing of each and every vehicle component is critically important to reduce the risk vehicle level nonconformities.  Elite engineers know this reality and have the equipment, expertise, and qualifications to get the job done on-time and correctly.

Elite's Test Facilities and Chambers

Elite has an impressive installation of EMC chambers to ensure manufacturers can start their validation testing on their schedule.  Our line up includes chambers that vary in size to support a wide range of products and monitoring equipment.   We have more ALSE chambers configured (and OEM approved) for  CISPR 25 testing than any other provider to ensure access to services.

ALSE Emissions Chambers10 ALSE chambers are configurable for CISPR 25 Radiated Emissions Testing.   Of these 6 are listed on our A2LA Scope of Accreditation for OEM accepted test results.
ALSE Immunity ChambersAll 10 of Elite’s ALSE Emissions chambers are configurable for RF Radiated Immunity, BCI, and Portable Tx Testing.
Shielded Chambers5 Shielded Chambers are setup for testing that does not need RF absorbing materials.  These include BCI, Conducted RF Emissions, and Magnetic Fields Emissions.
Reverberation ChambersElite has three Reverberation Chambers to support automotive, military, and commercial aviation testing.
Bench Test Stations12 bench test stations are provisions for Conducted Transient Immunity, electrical stress  testing, and various other unique procedures that don’t require a shielded chamber environments.
ESD LabElite’s ESD lab controls temperature and humidity to meet stringent OEM requirements. Within the lab are 5 ESD test stations, electrostatic voltmeters, and calibration/verification instrumentation.
