Application Summary AI generated

This standard specifies test methods for evaluating the immunity of automotive electrical/electronic components to electrical transients coupled into signal and control lines (non-supply lines) via capacitive and inductive coupling. It is applied in the automotive industry to validate that vehicle subsystems, such as sensors, ECUs, and communication buses, can withstand transient disturbances from adjacent wiring harnesses without malfunction. The standard is used during component development and type-approval testing to ensure electromagnetic compatibility (EMC) in road vehicles.
