Abstract

This document specifies general conditions, defines terms, gives practical guidelines and establishes the basic principles of the vehicle tests used in the ISO 11451 series, for determining the immunity of passenger cars and commercial vehicles to electrical disturbances from narrowband radiated electromagnetic energy, regardless of the vehicle propulsion system (e.g. spark-ignition engine, diesel engine, electric motor).

The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields. A wide frequency range (0,01 MHz to 18 000 MHz) is allowed for the immunity testing in the ISO 11451 series.

ISO 11451-2 Road vehicles — Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy — Part 2: Off-vehicle radiation sources

This standard outlines test methods for evaluating the immunity of complete vehicles to radiated electromagnetic disturbances using off-vehicle radiation sources. It builds upon the foundational framework established in ISO 11451-1, providing specific procedures and conditions for testing vehicle performance when exposed to narrowband electromagnetic fields in controlled environments. The goal is to ensure reliable functionality of onboard electrical systems and to support consistent, reproducible assessments across development and compliance testing.
