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.
Abstract
Overview
ISO 11452-9:2021 - "Road vehicles - Component test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 9: Portable transmitters" specifies laboratory methods to evaluate the electromagnetic immunity of automotive electronic components when exposed to continuous narrowband fields from portable transmitters in close proximity. Tests are performed with the device under test (DUT) and its wiring harness inside an absorber-lined shielded enclosure (ALSE) using simulated portable transmitters and controlled RF generation. The applicable frequency range is 142 MHz to 6 GHz. Safety and exposure guidance follows ICNIRP recommendations.
Key topics and technical requirements
- Test scope: Component-level immunity for passenger cars and commercial vehicles regardless of propulsion (ICE, diesel, electric).
- Test environment: DUT + harness in an ALSE; peripheral devices may be inside or outside the enclosure.
- Disturbance type: Continuous, narrowband electromagnetic fields from simulated portable transmitters.
- RF generation & instrumentation:
- RF generator with modulation per ISO 11452-1
- Power amplifier, dual directional coupler, power sensors or spectrum analyzer
- Low loss 50 Ω coaxial cable (VSWR
