KS R ISO 11452-4:2013 PDF

Scope: KS R ISO 11452-4 specifies wiring excitation methods and procedures for measuring the immunity of electronic components of passenger cars and commercial vehicles regardless of the vehicle propulsion system (e.g. spark ignition engine, diesel engine, electric motor). Total current injection ( The BCI) test method is based on the injection of current into the wiring device using a current probe as a transformer whose wiring constitutes the secondary winding. The Tubular Wave Coupler (TWC) test method is based on the bidirectional coupler concept. It is based on electromagnetic wave coupling inside the wiring device. The TWC test method was developed to test the immunity of automobile components to interference waves emitted in the GHz range (GSM band, UMTS, ISM2.4 GHz). This test method is most suitable for small (relative to wavelength) and shielded devices under test because the dominant coupling mechanism in these cases is through wiring. For devices under test larger than the wavelength (e.g. 0.1 m at 3 GHz), the direct field coupled to the printed circuit board (PCB) is of equal importance. Users of the TWC test method must consider and determine the applicability of this method. The electromagnetic disturbances considered in KS R ISO 11452-4 are limited to continuous, narrow-band electromagnetic fields.
