BS ISO 11452-9:2021

This standard BS ISO 11452-9:2021 Road vehicles. Component test methods for electrical disturbances from narrowband radiated electromagnetic energy is classified in these ICS categories:

• 33.100.20 Immunity
• 43.040.10 Electrical and electronic equipment

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.
