DIN EN 55025 VDE 0879-2:2009-03

This standard contains limits and methods of measurement of radio disturbance characteristics for the protection of receivers used on board of vehicles, boats and internal combustion engines against conducted and radiated disturbances produced by components built in the same vehicle. Methods for the measurement of the complete vehicle and for the measurement of components independent from the vehicle are established and limits for the electronmagnetic emission are given. The considered frequency range is 150 kHz to 2 500 MHz. This standard defines a numerous sets of limits as the installation location of the component, the construction of the vehicle chassis and the design of the harness can influence the coupling of radio disturbances in the built-in receiver. The components installed in vehicles are classified by disturbance duration to establish a matched range of limits which additionally are dependant of the selected method.
