Electromagnetic compatibility (EMC) means that a device/vehicle is compatible with its electromagnetic (EM) environment and also it does not emit EM energy that causes electromagnetic interference (EMI) to the other devices/vehicles. Electromagnetic compatibility tests for commercial vehicles are radiated electromagnetic emission tests and immunity tests to radiated electromagnetic disturbances. Electromagnetic emissions can be divided in two parts: Broadband emissions and narrowband emissions. “Broadband emission” means an emission, which has a bandwidth greater than that of a particular measuring apparatus or receiver.

“Narrowband emission” means an emission which has a bandwidth less than that of a particular measuring apparatus or receiver. Radiated broadband electromagnetic emissions from vehicles are generated by electrical or electronic systems fitted to the vehicle (e.g. ignition system or electric motors).

Radiated narrowband electromagnetic emissions from vehicles are such as might emanate from microprocessor-based systems or other narrowband source. Radiated narrowband and broadband emission limits from vehicles are set by commercial standard called ECE R10.  Limits apply throughout the frequency range 30 MHz to 1,000 MHz for measurements performed in a semi anechoic chamber or an outdoor test site.

ATS Group, thanks to an efficient Network of ISO 17025 accredited test laboratories, or qualified by ATS, is able to perform Electromagnetic Compatibility tests of Vehicles, Components and Technical Units, in compliance with the main National and International Standards or in accordance with specific requests from customers.
