NBN ISO 11452-9:2022

This document specifies test methods and procedures for testing electromagnetic immunity of
electronic components for passenger cars and commercial vehicles to portable transmitters in close
proximity, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric
motor). The device under test (DUT), together with the wiring harness (prototype or standard test
harness), is subjected to an electromagnetic disturbance generated by portable transmitters inside an
absorber-lined shielded enclosure, with peripheral devices either inside or outside the enclosure. The
electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields.
