Abstract

Overview

ISO 11451-3:2024 - "Road vehicles - Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 3: On-board transmitter simulation" defines standardized methods to test the immunity of passenger cars and commercial vehicles to electromagnetic disturbances produced by on‑board transmitters and portable transmitters with integral antennas. The standard applies across vehicle propulsion types (spark-ignition, diesel, electric) and covers the frequency range 1.8 MHz to 6 GHz. It is the fourth edition and forms Part 3 of the ISO 11451 series on vehicle EMC testing.

Key Topics and Requirements

Scope and test conditions: Specifies frequency range (1.8 MHz–6 GHz), test severity levels (user-specified; suggested levels in Annex D), and references general conditions from ISO 11451-1 (temperature, supply voltage, dwell time, modulation, etc.).
Test locations: Primary use of an absorber lined shielded enclosure (ALSE) per ISO 11451-2; outdoor test site allowed where regulations permit.
Test instrumentation: RF generator with modulation, power amplifier, dual directional coupler, low-loss 50 Ω coaxial cable, vector network analyser (VNA), transmit antennas, and artificial networks (DC charging AN, AMN, AAN).
Power monitoring: Forward/reflected power measurement via power sensors or spectrum analyser. Requirements include sensor VSWR < 1.2 and measurement accuracy < 0.5 dB; guidance for peak/average/pulsed measurements and broadband channel power.
Coupler and cable specs: Coupler coupling factor > 20 dB (40 dB recommended), directivity > 18 dB, mainline VSWR
