ISO 11452-4 Harness Excitation Testing for Components- 3CTEST

ISO 11452-4 Standard Introduction

Inquiry function description Comparison Function Description

ISO 11452-4 defines the harness excitation methods used to test automotive components against narrowband radiated electromagnetic energy. Instead of applying a field to the component, the method injects a defined radio-frequency current into the wiring harness that connects the component, which reproduces the practical situation in which the harness acts as a receiving antenna and carries the disturbance into the module. The standard covers the closed-loop and the substitution versions of bulk current injection, the tubular wave coupler method, and the direct injection of current into the harness with a probe. It defines the frequency range, the calibration of the injection fixture on a reference harness, the current levels that represent the corresponding field strengths, and the method by which those levels are verified during the test. Because the technique requires the harness to be representative, the standard specifies the harness length, the routing and the termination, and it explains how the module operates and how its performance is judged.
